Uba,

The velocities in your questions are too low. This leads you to conclude that the sum of the mass of the products is equal to the sum of the mass of the initial objects. The unchanging mass and the complete inelasticity of the collision means you can't use conservation of energy, or at least not the simple one that that uses kinetic energy only.

Trippy is able to keep track of all the energy because he's using conservation of energy in a fully relativistic sense, i.e. keeping track of kinetic energy and the energy in the rest mass of the objects.

The fact that the mass isn't invariant in the relativistic collisions seems to be one of your mental stumbling blocks.


Total energy and therefore relativistic mass are still conserved though, even if rest mass need not be. As a result, in an isolated system we should still expect momentum to be conserved, even under relativistic conditions (i.e. the velocity of the COM frame of an isolated system should remain constant to an intertial observer before and after the collision).

Trippy has argued that if rest mass changes, that the COM frame of the system would change relative to an inertial observer), despite no change in the energy/relativistic mass of the system.

And I have explained to you that your result violates the conservation of momentum. The velocity of the COM in your result is clearly different (relative to any inertial observer), post collision to it was pre-collision despite the lack of an external force acting on your system.



Only if you ignore the CHANGE IN MASS of the system.
Or are you closing your eyes and ignoring how I stated that I did the calculations?

A quick calculation suggests that a proton of 1150TeV is traveling at more like (1 - (4*10^-12 m/s)) * c
rather than (1 - (4*10^-6 m/s)) * c

Which means his Lorentz factor is out by a factor of about 1,000.

So his estimated momentum of the cosmic ray is too low by around three orders of magnitude and should be around 5.61x10^-13 kgm/s

We would therefore (according to Trippy's own calculations) expect the actual speed of the MBH to be around 1,000 faster than his v=274,402 m/s according to Newtonian conservation (which gives v=274,402,000 m/s).

Of course at these speeds we can no longer ignore the Lorentz factor associated with the MBH (since, despite Trippy's protestations, the MBH is indeed moving at relativistic speeds in earths reference frame) - so relativistic conservation of momentum is more appropriate, (at these speeds the Lorentz factor is still quite small though so the result isn't wildly different from the Newtonian result).

Not quite the same as your original 239 m/s result huh Trippy?

Mass of proton m = 938.27 MeV/c²

E = 1150 TeV = 1.150 x10⁹ MeV = γ m c² = γ 938.27 MeV

γ = 1.15 x10⁹ MeV / 938.27 MeV = 1.2257 x10⁶

= (1-u²/c²)^-½

1 - u²/c² = 6.6567 x10⁻¹³

u²/c² = 1 - 6.6567 x10⁻¹³

u = .999999999999667 c


Yes, Trippy has made an error. Still doesn't explain why Uba is trying to get us to consider low-energy collisions when the math isn't the same.

And if we set up a spreadsheet, we can determine that between an energy of 699 PeV, and 699.5 PeV, the residual velocity of the resultant blackhole drops from 11,001 m/s to 10,997 m/s (the escape velocity of the earth is 11,000 m/s).

To put that in perspective, particles with energies as high as 300,000 PeV have been observed, and particles with energies on the order of 700 PeV occur on average twice per km^2/yr


This is truly bizarre, do you actually think that the faster the cosmic ray is traveling (relative to earth and the stationary atom), the slower the resulting MBH will be (relative to earth)?
Trippy
Whatever.

Apparently I did make an error in my working as I stated I thought I might have when I attempted the calculations in the first place.

(still not sure where, and I'm not likely to be able to find it for myself (not through a lack of knowledge either).

The point is that my initial contention has been born out - the alleged black hole must be travelling slower then the Cosmic ray proton (and that in some cases, the velocity might be below the escape velocity of the earth).

I'm just glad that someone finally got around to actually doing some maths rather then jaw flapping.

Assume proton is in positive x territory moving in -x direction towards the second proton at rest at x = 0:
E_ is the total energy of the two proton system:

E_ = 1150 TeV + 938.27 MeV = 1150.00093827 TeV

p = γ m u = E/c² * u

From this point on I shall avoid the use of bold, although it is implied for u, p (since we are dealing with 1 dimension, the direction is simply designated by the sign). u1 is the velocity of the moving proton, u2 of the still one.

p_ is the total momentum

p_ = E1/c² u1 + E2/c² u2
= 1150 TeV/c2 * -.999999999999667164 c + 938.27 MeV/c² * 0
= -1149.99999999961724 TeV/c

This time m, u, and γ are the mass, velocity and gamma of the black hole respectively:

p_/E_ = γmu / γmc² = u/c²
= -1149.999999999661724 TeV/c / 1150.00093827 TeV
= -.99999918411/c

u = -.99999918411c (still quite fast, definitely relativistic)

γ = (1-.99999918411²)^-½
= 782.835

m = E_/γc² = 1150.00093827 TeV/782.835c²
= 1.46902 TeV/c² (1566 protons!)

Now the center of mass will have to be dealt with relativistically too. We'll use the relativistic mass M = E/c². Xcm is the position of the center of mass, Ucm is the velocity of the center of mass, M₁ and X₁ are the mass and position of the moving proton, U₁ it's velocity (I simply called it u in my previous post), and M₂ is the mass of the proton at rest:

Xcm = (X₁M₁+ X₂M₂)/(M₁+ M₂)
=(1150 TeV/c² * X₁ + 938.27 MeV/c² * 0) /(1150 TeV/c² + 938.27 MeV/c²)
= 1150 TeV/c² * X₁ / 1150.00093827 TeV/c²
= .99999918411 * X₁
Ucm = dXcm/dt
= .99999918411 dX₁/dt
= .99999918411 * U₁
= .99999918411 * -.999999999999667 c
= -.99999918411 c

And thus I have shown that the velocity of the center of mass before the collision is the same as the velocity of the black hole (and therefore the center of mass) afterwards. Conservation of the center of mass, if you will, as long as you use a relativistic center of mass.

Thanks barakn, as we would expect, the velocity of the COM of the system has remained constant in our frame (and indeed would in any other intertial frame).

This is the same derivation I used (or at least tried to).

But, apparently, I took a wrong step somewhere (check your inbox).

Irrelevant.

Actually, if you bothered to look into the facts before openeing your mouth, you'd realize something.

Ubavontubas first post to me was abusive - I stated that I believed someone else to be correct, he took the wrong end of the stick, got his nose out of joint and started abusing me. My attitude towards Ubavontuba is a direct reflection of his own actions.

Did you bother looking over the post that I linked to? No? Didn't think so, otherwise you'd realize how ridiculous that statement was. Yes, I missed what some may consider an obvious error when I sat down and created a spreedsheet, however when I looked at the way the residual velocity was behaving, while it seemed odd, it didn't seem (neccessarily) completely unusual - i'd explain further, but 1) it's not worth my time, and 2) it's not really relevant.

And if I was 'completely oblivious' to 'how silly it was' why do you think i've commented multiple freaking times that I suspected there might have been an error in it?

You're like a dog with a freaking bone. I have also stated, multiple times, many more times in fact, that "in some cases, the velocity might be below the escape velocity of the earth".

You know, if you're going to hold me to my most recent statements, hold me to all of them, and stop being such a hypocrite. Don't just do it when it suites you. An erroneous derivation does not invalidate my approach.

I may have been a little clumsy in handling the equations (something that even you have to aknowledge is not always the case), however, I was correct in principle.

My approach (and assertions) were correct, however the value I derived was inaccurate because of a clumsy derivation - I'm even willing to admit that the approach I used was not neccessarily the best approach (I had a pm'd conversation with someone else about my approach a long time ago).

I have asked/challenged, multiple times for people who disagree with me to do the calculations to prove it. Did you ever stop to consider, that maybe the tone I have used in some of my posts is a direct reflection of the fact that you haven't done this, and chosen to respond with the same sort of Jaw flapping as Ubavontuba? That in behaving in the same way as him, in spite of numerous requests/demands, that you lump yourself into a group of posters (including Ubavontuba) who like to sit around and prognosticate over physics they barely understand (See Ubavontubas claim that strapping rocket packs onto asteroids and throwing/dropping them at each other from gavitational infinity as proof of this). Did it occur to you in your self-righteous rampage that if you had simply done what Barakn has done and said "Well actually, the calculations show this, this, and this" that much of what has transpired could have been avoided?

No? Didn't think so.

My points are probably lost on you. For someone who has claimed the moral highground, you're doing a really poor job of keeping it.

Edit: As far as I'm concerned, the only person on this thread that gets bragging rights about proving me wrong is Barakn, because he's the only person that actually stepped up to the plate without jaw flapping.
Trippy
I think the most ridiculous thing about some of the things being suggested on this thread, is the way some posters are carrying on, you'd think I had claimed to be a great physicist or something.

I haven't, and never have.

In fact, anybody with the inclination to read my signature (or go through my post history) can see that the opposite is true.

I've stated repeatedly that I am a chemist, not a physicist. A Chemist with a slightly more advanced understanding of physics then most people (having studied it at university for two years).

I've never claimed to have an indepth knowledge of physics. Sure, I can do it, as I have proved, more then once on this forum (a fact that I'm sure Barakn, Alphanumeric, Rpenner, and even Ubavontuba have to admit), but nowhere have I claimed to get it all right all the time.

Almost equally ridiculous is the fact that.

1) These calculations ignore angular momentum.
2) These calculations ignore the fact that it's a collision between quarks (as Rpenner pointed out) and you can't neccessarily say anything about the momentum of the black hole after the collision based on the momentum of the proton before hand.
3) The fact that I might have erred in a derivation doesn't change the fact that if these things are persistent and as easily formed as Ubavintuba would have us believe, then there should be a veritable sea of micro blackholes with their velocities in a thermal distribution, meaning that the earth should have encountered one with a velocity less then the earths escape velocity (by now) and, well, we're still here.

I believe that LHC will produce mini black holes that will not evaporate. Several reasons. First the idea that mini black holes will evaporate is cavalier wishful thinking. Would we accept such assurances from a biotech lab? Suppose the lab reported revolutionary benefits of conducting an experiment where they insert small pox genes into an influenza host--with the solemn assurance that any and all samples will immediately be destroyed. Would we just let them waltz on ahead? I think not.

The other reason I believe that the mini black holes will be stable is because I am advancing a revolutionary new model, the Dominium, that suggests that mini black holes will stay stable as voracious matter compacting beasts. Debate has been hot and heavy on my Scientific American blog. Just go to SciAm.com, then to community, and then serch for my name "Hasanuddin." I invite anyone to come on over and join the “fun.” You wouldn’t believe some of the harsh words that my detractors have against me. The funniest thing is that the people with the harshest words adamantly declare that they have never read the model. Go figure? Of those who have read the model, they have nothing but positive things to say…though they all hope that I am wrong about the stable mini black-holes, or, if I am right, that LHC can be stopped in time.

If you do chose to join in the discussion, please read the model first. You can download the half-version of the model, links to do that are contained within the threads of my SciAm blog or you can purchase the full book (the paperback is more complete) at online bookstores

In retrospect.
Given that the ideas I used were correct (conservation of linear momentum before and after the collision)
Given that the equations I used were correct and applied correctly.
Given that the constants I used were correct.

It would seem that I did something like drop a bracket, or mis type a number when feeding them into my calculator.

Hi guys!

Just dropped in briefly to see what's up....and to point to some aspects I pointed to many times before, but that seem to be easily forgotten in the heat of 'clashes', hehehe.

In such collisions, the kinetic energy is MUCH reduced and dissipated in many ways:

- in overcoming the electromagnetic/coulomb forces even before the masses/partons actually toouh/merge/rebound etc etc;

- in temporarily reducing/cancelling altogether the PRE-EXISTING ANGULAR MOMENTUM of some mass/partons constituents/products as they exit the messy 'event';

- in temporarily increasing (many times?) the PRE-EXISTING ANGULAR MOMENTUM of other constituents/products;

- the ELECTRIC CHARGES of the products/constiruents involved will react with the electromagnetic field lines of the Earth....so 'slowing' some and 'speeding up' others;

- during the collision-phase proper, the ONLY 'mass/energy' DENSITY of any 'unusual value' is that part of the MOST COMPRESSED mass/energy that would FLEETINGLY occur in the EXTREMELY TRANSIENT and only TWO-DIMENSINAL 'film' of REMNANT mass/energy which ITSELF is (before, during, after collision 'event') IMMEDIATELY/ALWAYS vulnerable to all sorts of:-

. CLASSICAL (coulomb/electromagnetic etc) TURBULENCE and;

. QUANTUM PERTURBATIONS...

...... that TOGETHER AND THROUGHOUT act to prevent any LONG TERM 'stable/coherent' properties OTHER THAN for CLASSICAL (NON-'black' density) FEATURES/PARTICLES formed in the collision.



That LAST aspect of MASS/ENERGY DENSITY is, in my opinion, the MOST MISSED aspect in the arguments/stances from BOTH SIDES in these debates.

I say this because it seems that all and sundry appear to 'tacitly accept' without demure the idea that it is the ENERGY DENSITY that determines/defines the 'status' of a GRAVITATIONAL[/b] BLACK HOLE 'feature'.

Nothing could be further from the truth....and it bothers me that BOTH SIDES are 'blithely' accepting the VERY IDEA that:

- 'MICRO-MASSED 'black holes' can EXIST AT ALL; let alone that

- such PUTATIVE ONLY MICRO-MASSED 'black holes' can also FORM AT ALL in STRONG-GRAVITY 'unconstrained' free micro-particle collisions involving ONLY MINISCULE TOTAL CUMULATIVE ABSOLUTE GRAVITY STRENGTHS generated by the constituents/products before/during/after (the Earth's gravity not being involved in the 'event/products' collision/formation 'event' per se...except as a 'background' and NOT 'collision participant' factor!


Let's consider HOW a 'black hole' CAN BE made 'mass/energy' EXTREMELY DENSER than 'classical densities' IN THE FIRST PLACE; and also WHAT it is that KEEPS such 'extreme density' AT ALL:!

The clue is: a TOTAL MINIMUM CUMULATIVE ABSOLUTE GRAVITY and the ASSOCIATED production/presence of a TOTAL MINIMUM MASS/ENERGY ABSOLUTE QUANTITY.

Yes! It is that TOTAL MINIMUM ABSOLUTE which determines whether the body ALREADY creates the 'self-gravity' OVERBURDEN PRESSURES that IS NECESSARY TO COMPRESS the core material into extreme densities and keep them there!

DENSITY is therefore ONLY an [u]incidental
factor in gravitational feature' 'blackness/ stability' properties/behaviour.

The PRIMARY factor is TOTAL NECESSARY MINIMUM CUMULATIVE ABSOLUTE MASS/GRAVITY per se!

Anything that is NOT of that MINIMUM mass/energy TOTAL QUANTITY per se IRRESPECTIVE of 'density', will NOT form/maintain sufficient GRAVITATIONAL CONTAINM,ENT/PRESSURE against all the CLASSICAL coulomb/electromagnetic forces trying to BLOW UP' the MINISCULE MASS/ENERGY TOTAL....simply because these OTHER FORCES are MANY MAGNITUDES STRONGER than the puny miniscule total gravity strength of micro mass/energy features.

This is why FREE NEUTRONS quickly 'decay' into proton-electron and etc etc etc...simply because their TOTAL CUMULATIVE ABSOLUTE GRAVITY STRENGTH is incapable AT ALL of keeping it 'together' against the much greater foprces involved at that scale of mass/energy....irrespective of'density'.

Consider further:

Every NEUTRON STAR (extreme BOTH in mass/energy DENSITY and QUANTITY!) is hit with countless ultra-high energy particles. THAT energy density is ALREADY EXTREME, and any 'putative' 'black film' formed in a collision with its IRON 'shell' and inner neutronic contents SHOULD (ONLY IF others 'speculations/fears' are TRUE) ALSO produce a 'micro-black-hole' in an ALREADY EXTREMELY DENSE 'ENVIRONMENT'....which would produce a LARGER BLACK HOLE if the energy density argument was all there was to it! But there they are, neutron stars STILL.

Simply because, even IF any part of that neutron star was 'transiently' of even greater 'density' in a miniscule PART (where cosmic-ray proton collision occurs), the neutron star STILL HAS NOT the necessary MINIMUM CUMULATIVE ABSOLUTE TOTAL energy/mass QUANTITY/GRAVITY to make it 'collapse'.

And so, if NO neutron star with pre-existing EXTREME DENSITIES but STILL SUB-CRITICAL MINIUM MASS/GRAVITY can form a black feature from being hit with a relativistic high-energy particle, the what hope in heck will a MICRO particle with MINUSCULE mass/energy TOTAL CUMULATIVE GRAVITY have of froming, let alone sustaining a 'black hole' feature whose density (of whatever MINUSCULE/PUNY mass it does have) could NEVER KEEP IT AT those densities simply by its PUNY 'cumulative absolute total' GRAVITY....which after all, is only as strong as the 'rest mass' of the proton irrsepective of its puny gravity well's gradients 'profile'.


Anyhow, that's all I wanted to remind everyone on BOTH 'sides' about.....becuase the arguments seem to be 'skirting' the actual relevant factors (in my opinion from the outset).

Cheers and please forgive the typos as I AM in a real hurry today! Have fun and be polite...both these things needn't cost anyrthing if one goes about it the right and courteous way! hehehe.

Actually, if you bothered to look into the facts before openeing your mouth, you'd realize something.

Ubavontubas first post to me was abusive - I stated that I believed someone else to be correct, he took the wrong end of the stick, got his nose out of joint and started abusing me.  My attitude towards Ubavontuba is a direct reflection of his own actions.

That's not entirely true. You appeared to be rude to me, so I was rude in return. You protested, so I apologized. You've then continued to be consistently rude to me. So, it seems my first impression was correct.

Did you bother looking over the post that I linked to?  No?  Didn't think so, otherwise you'd realize how ridiculous that statement was.  Yes, I missed what some may consider an obvious error when I sat down and created a spreedsheet, however when I looked at the way the residual velocity was behaving, while it seemed odd, it didn't seem (neccessarily) completely unusual - i'd explain further, but 1) it's not worth my time, and 2) it's not really relevant.

Meaning you've no reasonable explanation.

That in behaving in the same way as him, in spite of numerous requests/demands, that you lump yourself into a group of posters (including Ubavontuba) who like to sit around and prognosticate over physics they barely understand (See Ubavontubas claim that strapping rocket packs onto asteroids and throwing/dropping them at each other from gavitational infinity as proof of this).

3) The fact that I might have erred in a derivation doesn't change the fact that if these things are persistent and as easily formed as Ubavintuba would have us believe, then there should be a veritable sea of micro blackholes with their velocities in a thermal distribution,

And I've pointed out that just such a "veritable sea" exists, in the form of dark matter.

Bullocks.

I got to thinking about what is happening, whether it is two protons becoming a black hole or the more likely scenario of two quarks. Black holes are allowed to have a charge and the scenarios involve the combination of two particles of either equal charge or uneven charge so that there's no chance of the charges canceling out to zero. I know of no reason (maybe by ignorance) that the black hole wouldn't acquire this net charge of the two objects. It would then act much like it did in its previous incarnation as a relativistic atomic nucleus, releasing Cerenkov radiation and scattering electrons. It would loose energy and momentum via the interaction of its charge with the Earth that it is passing through. It might be able to slow within escape velocity this way, leading me to again wonder why black holes haven't accumulated and swallowed the Earth up yet.

If you'll recall, I disagreed with BOTH of you, hehehe. I pointed out that in the real world, such messy collisions involving so many 'barrier' energies and possible angular/spin combinations in the eventual products in the 'splatter' event within the Earth's magnetic fields and ambient field will produce MANY 'frames' for practically EACH product. Think of it as the collision 'event' becoming 'practically' STATIONARY ABSOLUTELY for the fraction of a nanosecond that all those energy barriers, energy 'sinks' and quantum properties/effects that come into play CHAOTICALLY. There is no guarantee WHICH product/component will go WHERE and in WHICH direction and LINEAR (straight-line) momentum and ANGULAR (spin) momentum until all those forces/products COMPLETE and SEPARATE their initial interaction(s)......ESPECIALLY IF it IS a mostly INelastic interaction (which it must be for the kinetic energies to come into play....otherwise an Elastic collision would merely transfer kinetic energy to the 'target' proton which would move off IN THE PLACE of the 'incoming' proton....AS PROTONS and other ORDINARY DENSITY products).

Anyhow, you get my drift. BOTH sides are full of ASSUMPTIONS I do not subscribe to in 'free' collision scenarios at such high energies....INCLUDING those assumptions about micro-mass black holes forming/existing AT ALL IN THE FIRST PLACE.

Which reminds me. My last post had a formatting problem and came out much 'underlined' unintentionally. I meant to come back and clean it up but was distracted and never did. I will post it again for your benefit, as follows....

QUOTE (RealityCheck+Feb 23 2008, 12:08 AM)
.
Hi guys!

Just dropped in briefly to see what's up....and to point to some aspects I pointed to many times before, but that seem to be easily forgotten in the heat of 'clashes', hehehe.

In such collisions, the kinetic energy is MUCH reduced and dissipated in many ways:

- in overcoming the electromagnetic/coulomb forces even before the masses/partons actually toouh/merge/rebound etc etc;

- in temporarily reducing/cancelling altogether the PRE-EXISTING ANGULAR MOMENTUM of some mass/partons constituents/products as they exit the messy 'event';

- in temporarily increasing (many times?) the PRE-EXISTING ANGULAR MOMENTUM of other constituents/products;

- the ELECTRIC CHARGES of the products/constiruents involved will react with the electromagnetic field lines of the Earth....so 'slowing' some and 'speeding up' others;

- during the collision-phase proper, the ONLY 'mass/energy' DENSITY of any 'unusual value' is that part of the MOST COMPRESSED mass/energy that would FLEETINGLY occur in the EXTREMELY TRANSIENT and only TWO-DIMENSINAL 'film' of REMNANT mass/energy which ITSELF is (before, during, after collision 'event') IMMEDIATELY/ALWAYS vulnerable to all sorts of:-

. CLASSICAL (coulomb/electromagnetic etc) TURBULENCE and;

. QUANTUM PERTURBATIONS...

......              that TOGETHER AND THROUGHOUT act to prevent any LONG TERM 'stable/coherent' properties OTHER THAN for CLASSICAL (NON-'black' density) FEATURES/PARTICLES formed in the collision.



That LAST aspect of MASS/ENERGY DENSITY is, in my opinion, the MOST MISSED aspect in the arguments/stances from BOTH SIDES in these debates.

I say this because it seems that all and sundry appear to 'tacitly accept' without demure the idea that it is the ENERGY DENSITY that determines/defines the 'status' of a GRAVITATIONAL BLACK HOLE 'feature'.

Nothing could be further from the truth....and it bothers me that BOTH SIDES are 'blithely' accepting the VERY IDEA that:

- 'MICRO-MASSED 'black holes' can EXIST AT ALL; let alone that

- such PUTATIVE ONLY MICRO-MASSED 'black holes' can also FORM AT ALL in STRONG-GRAVITY 'unconstrained' free micro-particle collisions involving ONLY MINISCULE TOTAL CUMULATIVE ABSOLUTE GRAVITY STRENGTHS generated by the constituents/products before/during/after (the Earth's gravity not being involved in the 'event/products' collision/formation 'event' per se...except as a 'background' and NOT 'collision participant' factor!


Let's consider HOW a 'black hole' CAN BE made 'mass/energy' EXTREMELY DENSER than 'classical densities' IN THE FIRST PLACE; and also WHAT it is that KEEPS such 'extreme density' AT ALL:!

The clue is: a TOTAL MINIMUM CUMULATIVE ABSOLUTE GRAVITY and the ASSOCIATED production/presence of a TOTAL MINIMUM MASS/ENERGY ABSOLUTE QUANTITY.

Yes! It is that TOTAL MINIMUM ABSOLUTE which determines whether the body ALREADY creates the 'self-gravity' OVERBURDEN PRESSURES that IS NECESSARY TO COMPRESS the core material into extreme densities and keep them there!

DENSITY is therefore ONLY an incidental factor in gravitational feature' 'blackness/ stability' properties/behaviour.

The PRIMARY factor is TOTAL NECESSARY MINIMUM CUMULATIVE ABSOLUTE MASS/GRAVITY per se!

Anything that is NOT of that MINIMUM mass/energy TOTAL QUANTITY per se IRRESPECTIVE of 'density', will NOT form/maintain sufficient GRAVITATIONAL CONTAINM,ENT/PRESSURE against all the CLASSICAL coulomb/electromagnetic forces trying to  BLOW UP' the MINISCULE MASS/ENERGY TOTAL....simply because these OTHER FORCES are MANY MAGNITUDES STRONGER than the puny miniscule total gravity strength of micro mass/energy features. 

This is why FREE NEUTRONS quickly 'decay' into proton-electron and etc etc etc...simply because their TOTAL CUMULATIVE ABSOLUTE GRAVITY STRENGTH is incapable AT ALL of keeping it 'together' against the much greater foprces involved at that scale of mass/energy....irrespective of'density'.

Consider further:

Every NEUTRON STAR (extreme BOTH in mass/energy DENSITY and QUANTITY!) is hit with countless ultra-high energy particles. THAT energy density is ALREADY EXTREME, and any 'putative' 'black film' formed in a collision with its IRON 'shell' and inner neutronic contents SHOULD (ONLY IF others 'speculations/fears' are TRUE) ALSO produce a 'micro-black-hole' in an ALREADY EXTREMELY DENSE 'ENVIRONMENT'....which would produce a LARGER BLACK HOLE if the energy density argument was all there was to it! But there they are, neutron stars STILL.

Simply because, even IF any part of that neutron star was 'transiently' of even greater 'density' in a miniscule PART (where cosmic-ray proton collision occurs), the neutron star STILL HAS NOT the necessary MINIMUM CUMULATIVE ABSOLUTE TOTAL energy/mass QUANTITY/GRAVITY to make it 'collapse'.

And so, if NO neutron star with pre-existing EXTREME DENSITIES but STILL SUB-CRITICAL MINIUM MASS/GRAVITY can form a black feature from being hit with a relativistic high-energy particle, the what hope in heck will a MICRO particle with MINUSCULE mass/energy TOTAL CUMULATIVE GRAVITY have of froming, let alone sustaining a 'black hole' feature whose density (of whatever MINUSCULE/PUNY mass it does have) could NEVER KEEP IT AT those densities simply by its PUNY 'cumulative absolute total' GRAVITY....which after all, is only as strong as the 'rest mass' of the proton irrsepective of its puny gravity well's gradients 'profile'.


Anyhow, that's all I wanted to remind everyone on BOTH 'sides' about.....becuase the arguments seem to be 'skirting' the actual relevant factors (in my opinion from the outset).

Cheers and please forgive the typos as I AM in a real hurry today! Have fun and be polite...both these things needn't cost anyrthing if one goes about it the right and courteous way! hehehe.


RC.

I will be busy for a couple of days, so you and everyone have plenty of time to thionk about (especially) the point about minimum total absolute MASS/GRAVITY strength PER SE) as THE defining factor for forming/maintaining ANY 'black feature' densities against the internal NON-gravity forces that want to 'rip it apart' FROM INSIDE...not to mention the PUNY strength of any 'micro MASSED' object compared to external gravity effects from CUMULATIVE STRONGER gravity filed/strength distortions on any NON-'normal' 'micro-massed' gravity well feature/gradients (as pointed to in an earlier post)...and of course all the QUANTUM effects on such a STILL MUCH PUTATIVE and SPECULATIVE assumed 'feature' as 'micro' black holes.


So, until BOTH 'sides' in these debates can satisfy all my doubts in the areas mentioned, I will continue to disagree with BOTH 'sides' in many aspects of the discussion.

Being obviously wrong in principle means you don't understand what you're trying to calculate, to begin with!

The error you made was in not understanding how nonsensical your results were, before insisting they were correct.

It doesn't matter. Mistakes this large should be easily identified, on basic principles!

Do you?

I wonder this myself, seeing as it's you that's been wrong - all along!

You can't rationalize away such a gross error. There's no explanation that's acceptable beyond admitting you were completely wrong and you should've recognized it much sooner.

Obviously, I understand it better than you. ThePeanut probably understands it better than me though.

Rather, it is you that doesn't get it. Why don't you go away?

This must be some kind of an act, I find it hard to believe that you're genuinely this thick.

You're assertions that the basic principles I was espousing were wrong, is incorrect.
My calculations were based around the conservation of momentum.

I understood what I was trying to calculate.

And actually, I can rationalize the error you #######.

I was not completely wrong, my assertions were correct (and vindicated, even you've had to admit that the black hole slows down).

The fact that you've never attempted the calculations, and weren't able to say "I don't like it, it must be wrong" tells all of us that you don't understand it.

The fact that you can't understand classical results even when they're spoonfed to you tells us that you probably wouldn't understand relativistic results if they stood up and slapped you on the baldspot.

I get it, I understand it, I understand my errors, I understand why I made them, and I understand why I didn't catch them (and no, it's not through lack of knowledge as you've been insisting).

Meanwhile you're still struggling with the fact that my approach was based on the conservation of momentum, and was therefore conceptually correct. In fact, it was more then conceptually correct, because when Barakn used the same approach, he got the same numbers (the correct ones, that you've agreed with already).

So how's about actually reading what's posted on the thread before you go shooting your mouth off you idiot.

Now let's also remember that IF most of the MOMENTUM energies are used in overcoming the repulsive COULOMB forces before the particles can FUSE into a sufficient 'point-concentrated' mass (if we ignore for the moment the very important likelyhood that collision-front deformations would be severe, and result in 2-D 'sideways splatter' pattern of matter/energy which cannot form a central event mass/energy concentration etc), then there is LITTLE or NO MOMENTUM left for a nano-hole product to move off at any great speed (even IF it can be formed as you claim, hehehe).

OH NO! It's the Trippy argument all over again!

Are you trying to suggest that two colliding objects of equal mass and momentum do not collide and stop in the center of their energy/momentum? But rather, they stop relative to some preferred observer? I think not!

QUOTE
So your claim that the earth couldn't capture cosmic-ray induced nano-holes is NOT CONSISTENT with the fact that initial momentum energies have been SPENT in INELASTIC process of 'fusing' the particles into the dangerous energy concentrations you fear.

Spent where? Where's the center of mass/energy for the two colliding bodies? It certainly isn't preferential to the earth.

Hence, since most of the incoming cosmic-ray particle's MOMENTUM/KINETIC ENERGY (and hence 'velocity force') is SPENT in overcoming the COULOMB (REPULSION) electomagnetic forces between itself and the 'target' particle, then (IF such nano-holes can be produced in collisions between high energy 'free' particles), then they would be SLOW-MOVING after the collision.

You're viewing the "target particle" as somehow being fixed, as if it's inert.

QUOTE
After which the ONLY way such a cosmic ray induced nano-hole could speed up again and leave the earth would be if it was THEN accelerated by electromagnetic or other repulsive forces sufficient to overcome earth's gravity effect on the nano-hole.

Oh RC! I am deeply dissapointed in this assessment.

The conclusions from all this?

(1) IF nano-holes can be produced in free collisions, then the earth and every planet/star should have been 'eaten' by such nano-holes formed in their upper atmosphere; simply because most of their momentum/velocity-energy has been used up in its INelastic collision formation processes.

Not true. I suppose it must be natural to have this preferred reference frame bias though. It seems common enough.

QUOTE
BUT we are still here. Hence no nano-holes can form from free collisions. OR they are RE-accelerated away from those bodies.

Or, they smash through the earth like I contend.

You really have no concept do you?

The approach I took was accurate and correct. It fell over because somewhere, when I calculated the velocity of the cosmic ray proton, the figure I calculated was too low.

Ubavontubas first post to me was abusive - I stated that I believed someone else to be correct, he took the wrong end of the stick, got his nose out of joint and started abusing me. My attitude towards Ubavontuba is a direct reflection of his own actions.


Look it's not overly important, the last thing I'll say on the matter is that in my case, I initially posted an example demonstrating that the COM frame would have to move in the case of RealityCheck's scenario where he suggested the MBH would have little or no velocity relative to earth due to some sort of "splatter effect".

You argued there was a glaring error in my example because I was only considering one-dimension, I disagreed because it wouldn't change the conclusion, (COM must move, regardless of the number of dimensions we consider the two particle system in, in order for the MBH to have little or no velocity relative to earth (which violates momentum conservation).

Ok whatever, all I'll say is that increasing the energy of the cosmic ray proton leads to an increase in the velocity of the COM of the system relative to earth. Given the inelastic nature of the collision, the collision result will be moving along with the COM and therefore higher energy cosmic rays results in faster moving MBH's.

From a qualitative perspective, we wouldn't expect a slow moving object hitting a stationary ball in an inelastic collision to result in the two objects zooming off at relativistic speeds nor would be expect an object traveling at relativistic speeds colliding with a stationary object to result in the two balls proceeding at very slow speeds.

You're like a dog with a freaking bone. I have also stated, multiple times, many more times in fact, that "in some cases, the velocity might be below the escape velocity of the earth".

You know, if you're going to hold me to my most recent statements, hold me to all of them, and stop being such a hypocrite.


Even if I did cherry-pick statements (I haven't deliberately), I've never accused you of taking me out of context / cherry picking my statements so hypocrite isn't the correct term.

In any event, your calculation doesn't demonstrate how "in some cases, the velocity might be below the escape velocity of earth" either, in fact in the example you have used, all energy is used in the MBH formation so all black holes would be formed with the same velocity and therefore none would have a velocity below earths escape velocity.

You would need to come up with a different collision model whereby, for example MBH production is formed from the collision of two quarks only (as barakn and rpenner have suggested). You would then have a situation where the velocities of MBH's formed in these events would be distributed, with varying velocities, around a mean velocity co-moving with the COM frame and you could calculate the probability of a particular MBH having a velocity less than earths escape velocity.

I suspect the probability is extremely slim though considering the very high speed of the COM in earths frame.

I've lost count of how many times he's claimed "Fat and lazy doesn't work"


"Fat and lazy doesn't work" is an excellent analogy. The context of it was in response to your line of thinking that increasing the (rest) mass of the MBH automatically implies a decrease in the velocity of the MBH (relative to earth).

I'm not convinced you don't still subscribe to this line of thinking either.

QUOTE
It occurs to me to mention, that when I figured the mass of the (alleged) black hole I assumed that all of the total energy of the proton became the rest energy of the black hole. Another possible interpretation of what I said with the partons is that if only 2% of the total energy of the cosmic ray proton is converted into black hole rest energy, then the result is a black that is light enough, and has sufficient momentum to acheive escape velocity - a point that I have tried to make previously, but managed to mis-state.


This is actually the same line of thinking except the opposite, a lower (rest) mass of the MBH does not imply that the MBH must move faster (relative to earth), in fact, on average, MBH velocity will remain the same even if only a small amount of the total energy of the cosmic ray proton is converted into MBH rest energy.

In this context I could say "small and speedy" doesn't work.

I have asked/challenged, multiple times for people who disagree with me to do the calculations to prove it. Did you ever stop to consider, that maybe the tone I have used in some of my posts is a direct reflection of the fact that you haven't done this, and chosen to respond with the same sort of Jaw flapping as Ubavontuba? That in behaving in the same way as him, in spite of numerous requests/demands, that you lump yourself into a group of posters (including Ubavontuba) who like to sit around and prognosticate over physics they barely understand (See Ubavontubas claim that strapping rocket packs onto asteroids and throwing/dropping them at each other from gavitational infinity as proof of this). Did it occur to you in your self-righteous rampage that if you had simply done what Barakn has done and said "Well actually, the calculations show this, this, and this" that much of what has transpired could have been avoided?


I pointed out the error you made in underestimating the velocity of the cosmic ray proton. I calculated what your velocity meant the cosmic ray would only have an energy of about 1.05 TeV. I then calculated what the velocity of the cosmic ray proton should be (my result was very close to Barakn's - .9999999999996c vs .999999999999667c. I said that this meant your Lorentz factor would be out by a factor of 1,000 and therefore your cosmic ray momentum was underestimated by a factor of about 1,000.

I didn't check your calculations initially because I hoped I wouldn't need to. I tried to get you to see that your result clearly wasn't correct because it violated the conservation of momentum, and that this should've been clear by inspection, (i.e. without the need for me to perform any calculations) - the velocity of the COM relative to earth slowed dramatically after the collision if the MBH has a resulting velocity of just 239m/s. When it was apparent you weren't going to reconsider your calculations I pointed out that the velocity of the cosmic ray was too low, which prompted Barakn to step in and do the calculations.

So now you're going to go back and insist that the black hole stops relative only to the earth again? Haven't you already admitted that this assertion is wrong?

I've maintained that the blackhole slows down the whole dam time, a point that you have fought tooth and nail against.  The point is, that even in ThePeanuts scenario, the blackhole MUST SLOW DOWN.

How does it do that?

This is unacceptable.  Here's a portion of our prior argument on this issue (based on my prior comment to AlphaNumeric; "Like how the earth couldn't capture cosmic ray induced nano black holes.")...  bolds added:


OH NO! It's the Trippy argument all over again!

Are you trying to suggest that two colliding objects of equal mass and momentum do not collide and stop in the center of their energy/momentum? But rather, they stop relative to some preferred observer? I think not!


Spent where? Where's the center of mass/energy for the two colliding bodies? It certainly isn't preferential to the earth.


You're viewing the "target particle" as somehow being fixed, as if it's inert.


Oh RC! I am deeply dissapointed in this assessment.


Not true. I suppose it must be natural to have this preferred reference frame bias though. It seems common enough.


Or, they smash through the earth like I contend.

As can plainly be seen, you were agreeing with Trippy's contention.  You've tried to sidestep this since, but you never admitted the error.  Until you do, we have nothing further to discuss.



Hi uba!

No mate. You are 'understanding' my comments in the contexts/assumptions of both your/others' 'scenarios'....a scenario that I say is NOT to be analysed in the usual manner as both 'sides' are doing.

I claerly said that the 'event' results in MANY 'frames' for all sorts of 'products' issuing from the event.....MEANING that while much mass continues in the original line of the incopming proton, THERE IS NO GUARANTEE that in EVERY CASE any 'putative' black hole is going to 'exit' that event centre in that same direction. In fact, depending on the DYNAMIC INTERPLAY of all the forces/charges/turbulence/quantum uncertainties involved, the 'putative' micro-hole feature may exit BACKWARDS along the original line....or slow to a RANGE of velocities DEPENDING ON WHERE THE OTHER PRODUCTS and LINEAR/ANGULAR (spin) 'kinetic/momentum/other' energy 'sinks' are going after the event is 'settled' and 'explodes' away from the event space.


Also, there are the collision analyses that I disagree with on both sides. Take for example your suggestion to Trippy to understand the basics of momentum in your 'low energy' collision of cae/truck. I say that is totally irrelevant and misleading in that the car/truck have NO ANGULAR MOMENTUM PROPERTIES (no spin) and NO ENERGY BARRIERS (coulomb etc) forces surrounding them as WHOLE BODIES. So whereas the car/truck 'kinetic energies' are absorbed AS 'random LINEAR MOMENTUM 'kinetic energy' HEAT spread over their BULK of MYRIAD particle constituents throughout the two 'merged' bodies, SINGLE 'free' particles have SPIN, and any 'kinetic energy' is dissipated by ANGULAR MOMENTUM kinetic energy' AS WELL as any LINEAR MOMENTUM 'kinetic energy' of the SINGLE PARTICLES.

Moreover, whereas there are REPULSIVE BARRIERS/FORCES associated with EACH WHOLE BODY particle in 'free particle' collisions, there is no analogous WHOLE BODY repulsive 'barrier energy/forces between car and truck...so NO such kinetic energy 'sinks' are involved in low energy, macro body collisions AT ALL.


Still further, at the MACRO SCALE of car/truck collision 'event center', there is NO QUANTUM UNCERTAINTLY FORCES/EFFECTS in the 'absolute' spacetime processes 'location/frame' sense...since the macro body collision event 'starting constituents' and 'product constituents', as well as the overall event 'space' is NOT subject to such 'absolute' spacetime location/frame quantum fluctuations/uncrtainty effects/forces.

See? The car and truck momentum analysis (quite apart from the relativity factors already mentioned by barakn and others) does not involve all these other nano/quantum scale/particle natures/properties or whole-body 'barriers' and 'forces' and 'energy sinks' etc that make INelsatic 'free particle' collisions VASTLY DIFFERENT from, and cannot be analysed like, 'normal' macro-body type collisions which EFFECTIVELY INVOLVE MYRIAD 'BOUND' PARTICLES IN MACRO BULK BODIES way ABOVE the nano/quantum world in which the cosmic ray proton and atmospheric proton collision occurs.

Hint: the analysis in an EXTENDED MACRO-SCALE SPACETIME EVENT CENTRE is QUALITATIVELY DIFFERENT to MICRO is only relevant to MICRO analysis of POINT-LIKE QUANTUM-SCALE EVENT CENTRES where OTHER MORE POWERFUL ENERGIES/BARRIERS are involved that are INSIGNIFICANT in the macro scale collisions/event centres. Not to mention that in macro car/truck event, the Earth;s magnetic fields and other magnetic fields have NO significant ramifications for the 'event centre' and its MACRO BULK starting/product contituents.

Anyhow, please take the time to actually comprehend what I have been getting at that is DIFFERENT FROM BOTH 'sides' so far in these discussions. OK? I disagree with both of you. Any 'apparent' 'agreement' you 'perceive' is due to you 'misreading' what I have been saying re the collision analysis IN ALL ITS FACETS.

.
Now that I have cleared that up, perhaps you will suppress your misplaced indignation and think further on the OTHER even more important aspect of TOTAL MINIMUM CUMULATIVE ABSOLUTE GRAVITY STRENGTH requirement for GETTING AND KEEPING 'extreme' densities PER SE in the first and all cases....that being the DEFINING REQUIREMENT to form/maintain any extreme density 'featurte' AGAINST INTERNAL COULOMB/DYNAMIC ETC FORCES which will in the absence of such cumulative minimum absolute gravity 'containment' effect.

This aspect is the crucial one that you and others must resolve in order to 'allow' micro-holes to form/exist AT ALL as speculated. OK?

The IMPORTANT thing being that, NO MATTER HOW 'sharp' a micro-MASSED partlicle 'density' may have, the overall CUMULATIVE ABSOLUTE GRAVITY STRENGTH is PUNY IN ABSOLUTE CUMULATIVE GRAVITY TERMS/EFFECT/INTERACTION....not to metion that quantum scale effects will IMMEDIATELY make any putative' SHARP' gradient vulnerable and UNCERTAIN at best, and most likely DISRUPTED IMMEDIATELY to 'extend' to normal gradient and allow the particle to 'extend with it to 'normal' particle densities.



So, take a few days to think about all MY OWN posted points AS I MEANT THEM and not as you/others may have 'misread' them, hehehe.

Perhaps next week I will have more time to spare. I will see how things have gone then.

Cheers all!

6) Approach matters, I was correct in principle.
7) See previous discussion with thepeanut in which thepeanut agreed that the blackhole slows down when considered from either the Center of mass frame, or the earths frame.
8) Do not understand that because we're considering things from the earths perspective (because the original question related to the earths frame) that when I use relative terms, it should automatically be considered in that frame, unless otherwise stated? I thought you were smart enough to figure that out for yourself, guess I should have expected less from someone who needed "Perpendicular to the direction of motion" defined for them.
9) My assertions used the conservation of momentum as a starting point. I've lost count of how many times I've stated this.

The fact that you continue to insist that the blackhole does not slow down, suggests that you do not understand anything thepeanut has had to say.

You can't derive classical results.
You can't derive relativistic results.

Trippy
Ubavontuba, here's the point that you miss.

And RC, based on the PM you sent me, maybe you need to pay attention to this as well.

I've admitted that I erred in my calculations. My calculations were conceptually correct - they used the right formulae in the correct contexts, but I made an error somewhere in the execution - wether it was dropping some 9's in transferring information from calculator to paper and back again, misplacing a bracket when feeding the formula to my calculator, at this point, I don't know, and it's largely irrelevant.

The equations I started from were the correct equations.
The premise I started from was a correct premise (conservation of momentum).
The derivations I performed, and the substitutions I made were without error.

Big deal. I botched a calculation. So did Einstein, he corrected his error and moved on, it didn't invalidate his entire paper. I've tried to move on, but because you've taken something I said out of context, you refuse to aknowledge what I got right. This is part of what irritates me, it speaks of small minded pettiness.

You claim that I didn't catch my error because of a lack of knowledge, this is untrue, I've demonstrated that I have a not unreasonable knowledge of physics, elsewhere on this forum, even to you (including my derivation of the conservation of energy for falling bodies - something to this day which you have not aknowledged as being correct). I've explained to you that I never considered the motion of the center of mass of the system because:
1) I considered your claim of considering a single proton over an entire nucleus contentious, but was willing to try anyway.
2) Because of 1, I was uncertain of the behaviour of the COM after the collision, because any considerations of momentum should take the impulse applied to the entire nucleus into consideration (a combination of cololumbic repulsion as the cosmic ray proton approaches the nucleus, and actual 'physical contact' over the duration of the collision).
The reason that this is important, is because if I had considered things from the COM refference frame, I may well have spotted the error that I made in my calculations. I made a conceptual error when considering the mass of the final blackhole while picking my way through the various equations, somewhere along the way I managed to convince myself that there was a non-linearity introduced (althought e=mc^2 is a linear relatioship, e=mγc^2, the correct equation to use for calculating total energy, is not) this, combined with the inverse relationship between mass and velocity (for a constant momentum) predisposed me towards expectnig a particular result, so, when I recieved that result (bar the caveats previously stated) I did not think to question it (in reality there's more to the situation then I've explained, but I feel no compulsion to elaborate any further to you). Dirac also made a conceptual error, however he was allowed to admit it and move on. I've admitted (or alluded to) mine already.

The fact that I have had to labour under your misconceptions about what I have said (not for the first time) has not made things any easier.

Also, in order to try and avoid making some of the errors that I have, I asked you (at least once) to cite values for black hole mass, and collision energy. Something that, to this day, you have not provided.

Greater physicists then I have botched calculations.
Greater physicists then I have had conceptual problems when bending their minds around maths.

So, to sum up.

1) I've admitted (or alluded) to the mistakes that I made, but have not been allowed to move on.
2) The incorrect answer does not invalidate the approach (just as the conversion errors in the mars probe you alluded to in a prior post do not invalidate the use of orbital mechanics).
3) You have yet to aknowledge prior posts made by me that have been proven to be correct and accurate.
4) You have yet to aknowledge that the incorrect answer was not due to an incorrect approach, or lack of knowledge.
5) You have yet to aknowledge that you have erred in other matters.
6) You have been unable to cite pertinent information, in spite of objecting to assumptions made during the calculations.

Niceties of my prior post aside.

Aside from that which I have already aknowledged (that my calculated residual velocity was in error) perhaps you'd care to explain, how, if you were arguing against a point I was never trying to make in the first place (that the blackhole somehow slows down after it has formed), you were still correct (or correct in any form really, because how can I be wrong on a point I was never trying to make).

And before you go off on a tangent - bare in mind that.

1) I have been using the phrase 'residual velocity' the whole time.
2) I've explicitly stated that when I say 'the blackhole slows down' I meant that 'the velocity of the blackhole after the collision is less then the velocity of the cosmic ray proton before the collision' it's just a dam site easier to type.
3) If, instead of making assumptions about what I mean (yet again) based on your own expectations, you had of sought clarification, or even simply said 'if by slow down you mean... then yes.' a lot of the nastiness could be avoided.

And let's face it, you're as guilty of nastiness as I have been, and you haven't just been dishing it back. Take a look at the post I made lastnight - aside from the opening comment, the post as a whole was politely worded (in fact, I thought I had gone back and removed the opening comment, apparently not) and yet your response to it was riddled with snide comments.

For the record, I'm not comparing myself to Einstein, Dirac, Kepler or Hawking, merely pointing out that if we apply the standards that Ubavontuba seems compelled to hold me to universally, then there's a lot of work we should be discarding as wrong, because mis calculations or conceptual difficulties led to erroneous results.

Me byes... I just say frak it.

Even if there's a slim chance that this thing stood the chance of causing untold damage, imagine what we could learn anyways. biggrin.gif

Everyone's just afraid of having their questions answered. And no matter what, playing with reality at this high an energy will tell us something... even if it comes back that we really shouldn't be playing with reality at this energy level on Earth.

Screw it.

Cross your fingers and hope for the best.

At the end of the day, we might get another Fermilab magnet incident that just tells us we really can't manipulate energy levels like these across these distances within a gravity well. Pretty expensive lesson though.

Thats one thing thats lacking in any theoretical understandings of the multi-billion dollar toys we build. If we really don't understand gravity, we don't know if it will set its own energy level limit for these experiments naturally.

QUOTE (Trippy+Oct 26 2007, 11:26 PM)
In otherwords - Some (or all) of the kinetic energy of the proton is transformed into the rest energy of the black hole (This argument alone tells us that the Black hole MUST be travelling slower then the proton).

I'm not the one arguing that the momentum changes, you are.

What part of "The momentum of the black hole after the collision is the same as the momentum of the proton before the collision" equates to "The black hole has more momentum after the collision then the proton did before it".





QUOTE (Trippy+Sep 30 2007, 06:05 PM)
This is completely irrelevant. We could be talking about a Proton with a total energy of 10^19 eV, or an Alpha Particle with a total energy of 10^19 eV, the mass of the resultant black hole would be the same, as would the residual velocity of the black hole (before you start wailing and gnashing your teath, bare in mind that this simple means that the more massive particles are travelling slower).


QUOTE (Trippy+Sep 30 2007, 06:05 PM)
No, it's not. Your analogy actually backs up what I'm saying. Think about it. If the Needle is turned into another hay stack, by the collision with the first hay stack, do you really believe that the new haystack will keep moving at the same speed as the original needle? Conservation of momentum, which YOU bought up says no. This is the point that I've been trying to make (and was making).

Turning something small and fast into something heavy slows it down.



What did you think I meant all this time when I refered to Residual Velocity?


I also originally suggested that the produced blackhole would be stationary in the reference frame of the center of mass, a point which you argued against at the time (the error I made (perhaps) was suggesting that the Center of Mass was stationary, or nearly so in the oxygen atoms reference frame).

for example, here: http://forum.physorg.com/index.php?act=ST&...ndpost&p=278981

QUOTE (Trippy+Nov 1 2007, 11:20 PM)
An observer co-moving in the reference frame of the center of mass sees the oxygen atom almost at rest, but the cosmic ray proton moving at a large fraction of c. The pair collide, energy becomes mass, a singularity is formed, and is now also almost at rest.


Among others.
Trippy
And for the final time ubavontuba you narrow-minded quack - the error that I made was in considering the mass of the blackhole. Nothing more, nothing less.

I also (initially) considered a collision with an entire oxygen nucleus (as free protons in the atmosphere are very hard to come by) considering a proton colliding with an oxygen nucleus requires the center of mass to be 1/16th of the distance between the proton and the oxygen nucleus (and the oxygen nucleus to be moving at 1/16th the velocity of the proton - in the frame of the COM).

Get over it. It was consdieration of the blackholes mass that led me astray. NOTHING ELSE.

You say : You mean to say:
As I have already said, if we were to measure the rest MASS of a Proton with a total energy of 1150 TeV, we would find that it only weighed 4.7 TeV. This includes the other nonsense that you keep blithering about.


You correct Trippy about the need to say 'rest mass' but infact you're wrong. The rest mass of an object is invariant. Doesn't matter what velocity it's moving at, it's the REST mass. It's the mass of the object AT REST.

Staggeringly complicated I know, but obviously too much to grasp.

Besides, if you knew anything about relativity, you'd know that the rest mass of an object is invariant because of the fact Lorentz transforms leave the metric unchanged. You have :

-m² = p_a p^a
Apply a Lorentz transform :
-m² = p_a p^a = p^c p^d L_c^a L_d^b η_ab = (L_c^a L_d^b η_ab) p^c p^d = η_cd p^c p^d = p_c p^c = -m²

Thus p and L(p) have the same rest mass. It's easy to mathematically derive and it's easy to understand due to the name REST mass.

So much for you grasping even the simplest details of relativity.

That's for sure.


Always question your results. Always apply the principles of critical thinking.


No you haven't. You keep telling me your concepts were correct. If you're finally admitting they were not, than I applaud you for your growth as a person.


I'm very sorry it's been difficult for you. How much more difficult do you think your insults have made it for me?



That's right. I've aready said that you're in good company. The fact that you now realize the error, puts you a step above the guys who wrote the CERN safety study.


It is a difficult way to describe the universe. It's too easy to rely on too simple a model. I suppose it'll have to do though, since it's the only tool we have (besides experiment).


Please, do move on. You have my blessing.


This is true, but I think the error was too basic, too contrary to common sense to
so easily dismiss. I hope that in the future you will apply a more critical analysis of your own results. That would be a good thing.


Which ones? As far as I know, we've had only the two entanglements. The first, you didn't get conceptually, and the second is this one.

Perhaps you'd like to make another go of the first? I'd be willing, if you could show a little more maturity and patience.


I've alluded to it. I think you honestly tried to get it right.


Where? When?


That's because I'm one of a few that (independently) recognized the CERN error. There isn't a lot of information available. Most physicists still cite CERN's cosmic ray argument, even though it's clearly invalid. Like I said before, your current level of knowledge places you in the unique position of knowing something many "real" physicists don't. You should be proud.

Oh Bull, I've been admitting for days that the final number for the velocity that was spat out was wrong.



Hmmm. Let me see... When you're saying "You don't understand the conservsation of momentum" How could understanding the conservation of momentum, and being able to manipulate the numbers possibly be relevant.

Gee. I wonder. And no, I would not expect a professor to give high marks for style over content. But I would question any professor that didn't give half marks for 1) Understanding the concepts and knowing which equations to use, and 2) Being able to manipulate those equations correctly - especially when dealing with velocities where calculator error becomes important.



Need I point out that you deride other people for making simplifications in their equations? Wassamatta, your own pill too bitter to swallow?

As far as landing on my face goes? At leat I got up off the couch. I may have got the magnitude of the change wrong, but you argued against the existence of a change at all (therefore, you were wrong).



No. It is exactly untrue. And this contention is precisely why I will not simply let it go.



Pot... Kettle...



Oh FFS, How many times have I told you, I have never been assuming the COM is attached to the earth. I have never been treating the earth as some sort of preferred reference frame. Get a grip.



Once again, you're twisting my words out of context (which makes you a liar). I've stated, multiple times that the conceptual error I made was in considering the mass of the (alleged) blackhole.



Oh give over.



No, I'm not admitting my concepts were incorrect. They were correct, I had the right idea, wrong numbers.



Arrogant much?



Oh Bull. Just take a moment to think about what you're saying.



Admit my approach was correct.



Then, you'd be wrong.



How about... NOT. And again... Pot... Kettle...

And as far as Prior entanglements (and things you have yet to aknowledge I got correct) How about: Feeding rates, Cosmic ray collisions, and conservation of energy in a falling body for a start.



Then say the words "Trippy, you had the right idea, but the numbers themselves were wrong".



Oh, so all of a sudden you're the saviour of physics? That makes You, Farsight, TrueRelativity... Hmmm... So many saviours, which one do I believe?

Black hole mass is irrelevant to the outcome. Collision energies (for the cosmic rays) has always been implied to be equal to or greater than the expected LHC energies.

This is just speshul.

So what you're saying is that the mass of the blackhole is irrelevant when trying to consider the residual velocity of the blackhole with the momentum of the proton before the collision?

When did you last refer to "residual velocty?"


But you insisted the COM would be stationary relative to the earth, which is clearly not the COM!

You also said "You're only saying this now because I corrected you"

A statement which is clearly false, given that I've been saying it since October.

As for the rest of your post, it's just you managing to contradict yourself yet again, and prove my point for me.

Aside from this point: I never claimed the Center of Mass was stationary in the Earths reference frame. The words I used were "Nearly stationary" Stationary is not the same as nearly stationary.

Nearly landed on the runway has a significantly different result from landed on the runway.

You correct Trippy about the need to say 'rest mass' but infact you're wrong. The rest mass of an object is invariant. Doesn't matter what velocity it's moving at, it's the REST mass. It's the mass of the object AT REST.

Staggeringly complicated I know, but obviously too much to grasp.

Besides, if you knew anything about relativity, you'd know that the rest mass of an object is invariant because of the fact Lorentz transforms leave the metric unchanged. You have :

-m² = p_a p^a
Apply a Lorentz transform :
-m² = p_a p^a = p^c p^d L_c^a L_d^b η_ab = (L_c^a L_d^b η_ab) p^c p^d = η_cd p^c p^d  = p_c p^c = -m²

Thus p and L(p) have the same rest mass. It's easy to mathematically derive and it's easy to understand due to the name REST mass.

So much for you grasping even the simplest details of relativity.


I find it hard to believe you can find the mistake in ubavbontuba's post while ignoring the fundamental problem in the initial statement by Trippy. If you are going to accuse ubavontuba of failing to grasp the basics of relativity, shouldn't you also do the same to Trippy?

Hi uba! Back earlier than planned.

Hehehe. Awww, come on now, mate....you and every regular here at Physorg KNOWS by now that I don't play those 'personal' games; nor do I play the 'compounding the misunderstandings and starting futile/irrelevant side-arguments' games either!

Let's not play such 'games' now, shall we, you and I?

You know all my original inputs/arguments contributed so far that were NOT previously considered by EITHER 'side' in these debates.

You know that I disagreed on, and put my OWN dissenting explanation of the real nature/outcomes of 'free particle' collisions/momentums in charged particle relativistic 'collision' events which are NOT as simple re momentum/energy-mass tranfer and 'exit trajectory/velocities as EITHER SIDE is making out.

You know also that I continuously DISAGREE with BOTH side's arguments regarding formation/persistence of MICRO-MASSED (putative) black features because of the QUANTUM UNCERTAINTY and DYNAMIC FORCES involved that would destabilise the collision-front 'extreme density film' before it couls even co-alesce into ANY coherent symmetrical feature AT ALL, even if the puny gravity/gradients ARE considered.

And most important of all, you KNOW that my MINIMUM ABSOLUTE CUMULATIVE GRAVITY REQUIREMENT for getting/maintaining ANY 'black' DENSITIES is MISSING in BOTH 'sides' arguments....which makes BOTH sides arguments MOOT.


So mate, forget your petty 'feuds' with others based on mutual misunderstandings at every turn....and CONCENTRATE ON THE 1000 POUND GORRILLA in the room; namely.....


The ABSENCE of the necessary minimum absolute cumulative gravity STRENGTH required to GET any 'dark' DENSITIES IN THE FIRST PLACE.....and then to KEEP IT THERE against all the INTERNAL STRESSES FROM FORCES many magnitudes GREATER than the particle's PUNY and RELATIVELY INSIGNIFICANT GRAVITY.


See?

There is NO DANGER from any such still PURELY IMAGINARY beasts as MICRO-MASSED black holes....BECAUSE THEY CANNOT FORM OR PERSIST without the minimum cumulative absolute STELLAR-SCALE SELF-gravity required to make and keep the 'black' densities.....which so far in the universe is ONLY POSSIBLE in MACRO STELLAR MASS gravity situations which HAVE the necessary minimum cumulative absolute GRAVITY STRENGTH to make and keep such densities....but ONLY where the MASS INVOLVED IS NOT 'micro-mass' but STELLAR SCALE MASS IN THE FIRST PLACE.

See?

NO WORRIES, mate!

So, UNLESS you can argue THAT minimum requirement away------again yet another source of DISSENT by ME from BOTH sides.....because BOTH 'sides' had so far considered 'extreme density' WITHOUT any thought given as to how such densities would STABLY BE PRODUCED and MAINTAINED AT ALL by such PUNY gravity as was available in free particle collisions------then I have just effectively allayed your and others' fears regarding ANY purely STILL IMAGINARY micro-holes from ANY 'micro-massed' free-collision event.

So both sides in these threads can now relax and move on to more important/immediate problems faced by humanity and this planet.

That's what I will be doing; for I have no wish to be involved further in 'chiuldish' squabbles over things which are NOT allowed by the laws of physics (relativistic micro-body/elementary charged-particle dynamics/energy-barriers; quantum process/uncertainty; AND insufficient absolute minimum CUMULATIVE MACRO-MASS gravity strength).

Hi Solid State Universe!

The minimum cumulative absolute gravity mentioned again in my latest post has to do with the SELF GRAVITY of a particle/body per se.

A FUEL-EXHAUSTED (and so collapsing) stellar+ body has sufficient MASS to provide the SELF-GRAVITY STRENGTH to compress and maintain EXTREME DENSITIES of its collapsed material AGAINST THE USUALLY GREATER INTERNAL REPULSIVE/DEGENERACY-PRESSURE FORCES.......

.....whereas a PUNY GRAVITY 'free' MICRO-MASSED 'particle' does NOT have that SELF-GRAVITY capability to form/keep itself in the 'extreme' density regime against ITS greater internal repulsive forces.

Remeber: Density does not produce 'darkness'....rather it is the GRAVITY that produces the 'darkness' AND also produces/maintains the DENSITY as a SECONDARY CONSIDERATION....the PRIMARY CONSIDERATION is the MINIMUM CUMULATIVE ABSOLUTE SELF-GRAVITY capability that onlt STELLAR-TYPE MASSES have to begin with that DOES produce dark densities when collapsed.


Remember: SELF-Gravity of LARGE MASS FIRST; mere Density of MICRO-MASS second....and NOT the other way 'round, hehehe!


Hence: NO MICRO-MASSED black holes can form/persist FIRST because NO STRONG SELF-GRAVITY to stably form/maintain extreme densities. Period.

Hence NO danger. Period.

All other arguments are MOOT unless we can get over THAT physical/logical hurdle, SSU! hehehe.

Cheers!

Trippy's statement was "As I have already said, if we were to measure the MASS of a Proton with a total energy of 1150 TeV, we would find that it only weighed 4.7 TeV."

The difference is that I've already admitted that I made some errors in my calculations (the early ones particularly).

The difference is that I inadvertantly swapped one word for another (weight and mass).

The difference is that Ubavontuba's statement is grossly wrong - I was referring to the weight, including mass inflation (μ v's m).

Ubavontuba's statement however implies that the restmass, which as you know is invariant, changed from 938 MeV to 4.7 TeV.

I think it's somewhat unfair of you to bring this up, especially given that the point I was trying to make was clear (at least I thought it was anyway), not to mention that earlier in the same post I clearly drew the distcintion between total energy and rest energy.

It also isn't the only example of Ubavontuba failing to grasp the basics of relativity, or classical mechanics. Not to mention the fact that I have already demonstrated to Alphanumeric both in PM's and other threads, that I actually grasp the concepts, even if I am a little clumsy with the math from tme to time.

The point being that Ubavontubas "Correction" not only completely changes the meaning of the sentence, but defies the known laws of physics.

That wasn't really what I was getting at, the relativistic mass of our 1150 TeV proton is simply 1150 TeV (divided by c^2) rather than 4.7 TeV (I assume the relativistic mass is what you were referring to since it is the mass we would measure the proton as having in our reference frame). This is because total energy and relativistic mass are equivalent (as you know).

I reviewed Trippy's equations and starting values -- they were correct. He made a calculator error, pure and simple. I'm willing to bet that every single person reading this post has made numerous calculator errors in his or her lifetime. While Trippy's numbers were off they still showed the correct trend, i.e. that the rest mass of the black hole (i.e. its mass in a reference frame at rest with respect to the center of mass of the black hole) was greater than the sum of the rest masses of two protons, and the velocity of the black hole with respect to the Earth's surface was smaller than the velocity of the incoming proton. If Uba still has an issue with that, for the sake of our sanity and for the revival of a discussion stuck in the mud, please just drop it.

It wasn't necessary to calculate these values in the first place. Various members of this discussion have discovered individual quarks are involved in the initial collision. I've seen a paper (but lost the link to it) that suggested the formative moments of the black hole are messy and a lot of energy is radiated away (which is something that RealityCheck has been trying to tell us). Our back-of-the-envelope (or is it cocktail napkin) calculations of a simple inelastic collision are incapable of describing what is actually occurring. Or maybe not - see this. Somewhere in that page it says the black hole could have a charge, so an assertion I made in a previous post that a black hole formed in this manner would strongly interact with and transfer momentum to surrounding charged particles remains unchallenged.

I think RealityCheck's arguments that these micro black holes don't have enough "SELF-GRAVITY" to actually be black holes is irrelevant. We are discussing black holes that are being produced at extremely low energies only because a small handful of string theorists have produced their own models of spacetime that are so different from the ordinary 3+1 (the phrase bandied about is "large extra dimensions") that small black holes become possible. What's especially funny about this is that not even other string theorists believe these black holes are possible.

Also there are hints of even weirder possibilities like this which suggests the black holes might actually pinch off from the dimensions we're familiar with and disappear into the extra dimensions. If you thought a black hole evaporating via Hawking Radiation was hard to swallow, how about a black hole performing a Cheshire cat routine? smile.gif

Trippy
Ubavontuba also argued that Neutrinos couldn't produce blackholes, inspight of the fact that I was able to produce a paper/talk from one of the authors of XLD who was prposing going searching for the particle cascade associated with the decay of blackholes produced by neutrinos by hawking radiation.

The general idea being that because the neutrinos (can) penetrate so deeply into the atmosphere before they interact, they're capable of forming black holes at very low altitudes, which has the advantage of filtering them out from other cosmic ray spallation events.

So not only does he (seem to) think that the authors of XLD are wrong when they suggest that Hawking Radiation is correct, but he also (seems to) think that they're wrong when they say Neutrinos produce blackholes, but they're correct about low energy blackholes!

I believe the phrase for this is 'cherry picking' (which is precisely what he's done to me, more then once).

That's not true.

I'm not even sure which part you are saying is not true. It is most certainly true that it is the LXD theories that led to TeV scale black holes. And it is true that other string theorists, while they admire LXD, don't believe they are correct. I can say this because I've read the last few paragraphs at the bottom of this link. If you clarify what you think is not true we can discuss it.

Highly probable.

I'd say evidence was demonstrated with the first 3D dark matter gravity map.

Notice the blob in the top right corner that tapers off?

I'd by that as a more respectable answer to the final fate of a black hole than Hawking Radiation, as well as providing the foundation for the white hole vacuum solutions.

(I've mentioned this before, but it usually gets ignored.)

No. Classical black holes are way too large to disappear this way.

Throw in MOND and declare gravity's reach to be finite and we might have to revise that theory.

I reviewed Trippy's equations and starting values -- they were correct.  He made a calculator error, pure and simple.  I'm willing to bet that every single person reading this post has made numerous calculator errors in his or her lifetime.  While Trippy's numbers were off they still showed the correct trend, i.e. that the rest mass of the black hole (i.e. its mass in a reference frame at rest with respect to the center of mass of the black hole) was greater than the sum of the rest masses of two protons, and the velocity of the black hole with respect to the Earth's surface was smaller than the velocity of the incoming proton.  If Uba still has an issue with that, for the sake of our sanity and for the revival of a discussion stuck in the mud, please just drop it.

It wasn't necessary to calculate these values in the first place.  Various members of this discussion have discovered individual quarks are involved in the initial collision.  I've seen a paper (but lost the link to it) that suggested the formative moments of the black hole are messy and a lot of energy is radiated away (which is something that RealityCheck has been trying to tell us).  Our back-of-the-envelope (or is it cocktail napkin) calculations of a simple inelastic collision are incapable of describing what is actually occurring. Or maybe not - see this.  Somewhere in that page it says the black hole could have a charge, so an assertion I made in a previous post that a black hole formed in this manner would strongly interact with and transfer momentum to surrounding charged particles remains unchallenged.

I think RealityCheck's arguments that these micro black holes don't have enough "SELF-GRAVITY" to actually be black holes is irrelevant.  We are discussing black holes that are being produced at extremely low energies only because a small handful of string theorists have produced their own models of spacetime that are so different from the ordinary 3+1 (the phrase bandied about is "large extra dimensions") that small black holes become possible.  What's especially funny about this is that not even other string theorists believe these black holes are possible.

Also there are hints of even weirder possibilities like this which suggests the black holes might actually pinch off from the dimensions we're familiar with and disappear into the extra dimensions.  If you thought a black hole evaporating via Hawking Radiation was hard to swallow, how about a black hole performing a Cheshire cat routine?  smile.gif



Hi barackn!

1. Regarding slf-gravity argument being moot due to 'other dimensions': It should be borne in mind at all times that my arguments are CLASSICAL (relativity/quantum vacuum).....any 'string theory OVERLAYS are actually IRRELEVANT in the FORMATION PHASE of any such imaginary thing as a MICRO-MASSED black hole. ONLY AFTER such imaginary things 'form' AT ALL will there be other speculative considerations.....BUT in any case, at the sub-planck SCALE of such a micro-hole, those 'extra dimensions' ARE EFFECTIVELY A PART OF THE UNDRRLYING QUANTUM VACUUM UNCERTAINTY PROCESSES that are ALREADY IN ACTION while the 'free-particle' collision EVENT ITSELF is playing out and until 'settled'.

So I beg to differ....

.....because from what I can see in my perspectives, that to form in the first place, any 'black-holes' of ANY KIND (ie, their central feature/singularity or whatever) must FIRST satisfy the CUMULATIVE MINIUMUM ABSOLUTE GRAVITY requirement in order for the 'event to BE BROUGHT DOWN TO THAT SCALE.....and only THEN can it AS A WHOLE FEATURE be AFFECTED WHOLESALE by and/or have ACCESS to, the sub-plank scale uncertainty' AND ANY still speculative OTHER DIMENSIONS 'world/processes' AT ALL. See?...my argument can't be avoided....since it takes precedence in the ckain of formative processes BEFORE any such 'micro-hole' GETS DOWN as a 'coherent feature' TO any other dimensions at those scales, hehehe.


2. And about the 'messy' relativistic free particle inelastic collision event analysis: Thanks......I was beginning to think that I was the only one on either 'side' of these debates to see that as obvious given all the factors present (and factors NOT present) in such single particle MICRO-collisions events compared to usual bulk body MACRO-collision events, hehehe!

I also would like to present for everyone's further consideration MORE obvious ramification (to me at least...as highlighted in bolded paragraph and lines/phrases below) of such Cosmic ray Proton to proton etc free-particle collisions on/around NEUTRON STARS:

- If such imaginary micro-holes could form/persist as claimed (in any scenario!), and if its accumulation/deceleration in/by such a PRE-EXISTING extreme density body as a Neurton Star, the it would be stopped almost immediately and very quickly turn the NS into a macro black hole.....

......BUT uba insists (without substantiation) that the (still imaginary) micro-hole would NOT be 'captured' because it would whizz through even such an extreme density NS body.....

......to which I have already countered that the 'free collision' that SUPPOSEDLY 'forms' the imaginary micro-hole in/on a NS (or anywhere) is 'practically stationary'....and that any imaginary micro-hole may come from the collision event in MANY RANDOM DIRECTION and with MANY RANDOM VELOCITIES, such that of the myriad numbers of such inevitable events in/on Neutron Star bodies, at LEAST ONE would have turned EVERY NS into a black hole...

BUT why aren't all NS black holes by NOW?....there could be only two reasons......

EITHER......the PRE-EXISTING absolute minimum cumulative mass/gravity necessary for compressing the Neutron Star body (and the imaginary micro-hole supposedly formed/stopped within) is INSUFFICIENT (or it would have been a macro-black hole already! hehehe), and so NO black-hole CAN BE formed/persist therein EITHER from the existing Neutron Star MASS (insufficient cumulative mass, hence insufficient cumulative gravity to compress to 'black densities) OR from the INPUT MICRO-PARTICLE MASS which definitely also lacked the necessary cumulative mass/gravity.....

OR......any imaginary micro-mass 'black hole' passes right through and escapes the Neutron Star body (which is NOT likely given the PRE-EXISTING extreme neutron Star densities/emag-forces involved in/around the Neutron Star).......

BUT, even allowing (for the sake of further pertinent arguments in THAT unlikely event) that a MICRO-HOLE 'would escape' AFTER IT WAS supposedly formed in particle collision, the time the 'event' occurred over would have the incoming proton colliding witth MORE THAN JUST ONE 'stationary' proton in the NS!....so the COLLISION 'EVENT' ITSELF IS STOPPED QUICKLY and the MASS INVOLVED in the 'collision' is MANY MAGNITUDES MORE than would be involved in Earth's relatively sparely-spaced atmospheric protons....

Which means that ANY COLLISION 'EVENT CENTRE' IN/ON NEUTRON STARS by cosmic ray protons is STOPPED/SLOWED/CAPTURED EVEN MORE EFFECTIVELY and EVEN BEFORE ANY 'BLACK FEATURE' IS FORMED AT ALL.....by the practically IN-LINE SERIAL COLLISIONS THAT WOULD CONTINUE AS LONG AS THE collision event LASTED UNTIL ALL ORIGINAL INCOMING LINEAR KINETIC ENERGY WAS SPENT in colliding with a 'line' of protons as long as the DIAMETER of the neutron star!

Imagine a 'newtons cradle' with a long chain of 'balls' ALREADY COMPRESSED AGAINST EACH OTHER......and a new ball coming in and IN-ELASTICALLY splattering itself against that PRACTICALLY IMMOVABLE (for it) line of balls!

It would be stopped dead (the only way the KINETIC ENREGY would NOT be SPENT IMMEDIATELY is if the collision was ELASTIC....and a'ball' at the opposite end of the 'line' of neutron star protons came shooting out!...BUT THEN there would be NO supposed imaginary micro-black-hole formed! hehehe.


.
In conclusion: There is no way to avoid it.....

EITHER the free particle collision IS practically stationary as per the existing clasical/quantum forces/effects, and any imaginary micro-hole IS ca[ptured by Earth and other more massive dense macro bodies;

OR if the collision is 'moving' all the time, then it MUST ENCOUNTER a veritable IMMOVABLE-LINE OF NEUTRON STAR PROTONS and is PREVENTED from going any distance before being slowed and captured due to the VASTLY INCREASED mass of the in-line NS protons NOW INVOLVED in the event in a NEUTRON STAR (and yet, there exist NEUTRON STARS that haven't been turned into 'black features'....not only because micro-holes cannot form/persist under ANY scenario as already explained...BUT ESPECIALLY becuase even an already extreme-densty feature like a NS should be EASILY TIPPED OVER TYHE EDGE BY ANY SUCH THINGS if thay can form/persist AT ALL without the necessary cumulative gravity strength CONTAINMENT against INTERNAL FORCES that would expand the feature to classical E-MAG AND OTHER CHARGE-INTERPLAY/ENTANGLEMENT body densities like protons etc WHICH I HAD LONG AGO POINTED OUT in earlier threads).

SO.....any 'sub-plank' and STRING THEORY 'other dimensions' considerations must FIRST be preceded by classical/quantum requirements in the 'collision itself' BEFORE any imaginary blavk feature CAN be brought DOWN to the scale AS A WHOLE FEATURE for it to be part of those 'other world' processes/hypotheses.

I am terribly short of time....so instead of writing a whole TREATISE on these things, I have tried to explain BRIEFLY 'piecemeal' as the arguments went on. Whatever the 'understanding' of anyone here about my explanations to date, I think given the record of all my many original inputs since the beginning of this and earlier LHC threads, you will agree and understand WHY IT IS that in many cases I have DISAGREED with BOTH 'sides'....simply because NEITHER 'side's arguments invoked the many RELEVANT and TELLING points/observations I have put...even as others were arguing over 'trifles' and 'speculations' and 'imaginary artifacts' that only tended to exacerbate mis-understandings and 'games' in lieu of proper focused and RIGOROUSLY PHYSICAL/LOGICAL debate of the commonly observable facts/phenomena that I have been trying to infuse into the sometimes 'emotional' and 'cross-purpose' so-called 'debate'! hehehe.

Cheers all! Back in a few days to see if we are finally at the REAL WORLD fair-dinkum 'factual' and 'non-imaginary' stages of this debate yet!

PS: Thanks again, barakn, for your timely/reasoned/calming posts...these 'emotional and/or political' undercurents' threads need more of your posts! hehehe.

MOND is irrelevant.
MOND can not replicate reltavistic results (hence the existence of TeVeS).
MOND can not replicate gravitational lensing (in fact it doesn't predict it, period) (Hence the existence of TeVeS).
