If the European findings are correct, "this would change the idea of how the universe is put together," Columbia's Greene said. But he added: "I would bet just about everything I hold dear that this won't hold up to scrutiny."

Thanks for those comments. There's to much existing evidence that neutrinos speed is < lightspeed. Measuring the distance using the GPS isn't going to get it. They need to measure the distance so the measurement error bar is in the same order as the rest of the experimental error bar. I would do the experiment over a much greater distance so + or - would be pronounced.
Mazulu
Until the results can be confirmed somewhere else, treat it like an equipment problem.

On the other hand, Cern could "make lemons out of lemonaide"; they could try to give the neutrinos more energy and see if they go even faster. That is a sure fire way to figure out what they did wrong.

It also helps to understand how neutrinos are detected.
http://en.wikipedia.org/wiki/Neutrino_detector

Another possibility is that they overestimated the distance the neutrinos were traveling. That's my bet. cool.gif

This is posted on the physics site at Cornell:

Measurement of the neutrino velocity with the OPERA detector in the CNGS beam and .pdf and at a seminar at CERN. So simply because the news is covered in non-scientic media doesn't mean it's not a legitimate item.

Note that the experimenters were looking at three years of data, measuring velocity 15,000 times. Normally this certainty would be counted as a discovery. Since it conflicts with a well established theory, the CERN scientists opened the results to scrutiny.

That being said, I'd be surprised if the results are duplicated. The only fudge factors in the light-speed limit are space and time. And mass. Even if somehow the neutrino could shed its tiny mass, it still couldn't exceed c. Still, data is data.

Nah, there have been obscure neutrino as tachyon models for some time now. Relativity would stay intact. Tachyon physics would go from fringe to mainstream research.
Frankly I doubt they have the timing of the creation event at one lab to the reception event at the other lab down to the 10ns claimed. Even if they do a statistic will have to be run for many trials as that times so small the energy time uncertainty may lead to as much error.
Mazulu
From the article, this is how they define neutrino velocity.

QUOTE
In this paper we report on the precision determination of the neutrino velocity, defined as the ratio of the precisely measured distance from CERN to OPERA to the time of flight of neutrinos travelling through the Earth’s crust.


I'm sure that they checked their software for errors. Mmm... I hope it's true.

It becomes legitimate when the detailed paper explaining the experiment and results are opened to scrutiny. The paper provides literature and the AP sensationalizes. That's how it works with humans. I think it's going to be very difficult to duplicate. I like an experiment which can make a direct comparison between the speed of light and the speed of the neutrino over the same path. The possibility for unrealized systematic error and comparing a measured neutrino time to the assumed time for light makes me think they need to find a better way to confirm or deny the result. Just my opinion which doesn't count anyway. Thanks for the link.

Was just watching the news and it said they original scientists duplicated the faster than light travel over 15 000 times.

Also said they're publishing the work today to let someone else try to duplicate the results.

[UPDATE: The paper is now up on the arxiv preprint server. I took a look, and must say at first glance their reasoning looks solid. They appear to have the baseline distance nailed and the timing as well. However, the devil's in the details, and this isn't my field, so I'll be very curious to see how the pros in this discipline react to the paper.]
So Plait himself is scratching his chin too.
Wasn't I pleased when I read waitedavid137's comment. Tachyon mechanics is the first thing I thought too, if the readings hold (notwithstanding my relative ignorance of the field). Aren't there papers by Ed Witten on this?

If MINOS were to confirm OPERA's find, the consequences would be enormous. "If you give up the speed of light, then the construction of special relativity falls down," says Antonino Zichichi, a theoretical physicist and emeritus professor at the University of Bologna, Italy. Zichichi speculates that the 'superluminal' neutrinos detected by OPERA could be slipping through extra dimensions in space, as predicted by theories such as string theory.

They did do this experiment for a reason. Its not like they did an experiment and just "happened" to notice that the detector at San Grosso were picking up the neutrinos 60ns earlier than light should arrive. They very deliberately planned the experiment for this exact purpose, that tachyon neutrino models have been around for at least a decade and had yet to be tested. If confirmed there will be Nobel prizes in this one. If they screwed up, a lot of embarrassment.

Could the difference be due to the acceleration of Gravity?

What is the relative height of the source and the receiver to sea level. For the receiver I have an average depth of 3800 meters. Don't know if that is to ground level or sea level.

I cannot find the relative height of the source. I might not be looking hard enough.

I think what gets David is the dumb comment the poser made. He acted like relativistic physics is going to get round filed if this is true. That just shows he doesn't know what he's talking about. I know what the adopted speed of light is but I wonder what the measurement error bar was for the measurements themselves. The number they are talking about with the 10ns claim for complete error bar is probably going to bite them in their collective posterior.

worst case scenario relativity becomes like Newtonian physics accurate but not the whole story...and that is worst case mind you.

from the published paper:

The OPERA detector at LNGS, designed for the study of neutrino oscillations in
appearance mode, has provided a precision measurement of the neutrino velocity over the 730 km
baseline of the CNGS neutrino beam sent from CERN to LNGS through the Earth’s crust. A time
of flight measurement with small systematic uncertainties was made possible by a series of
accurate metrology techniques. The data analysis took also advantage of a large sample of about
16000 neutrino interaction events detected by OPERA.
The analysis of internal neutral current and charged current events, and external νµ
CC
interactions from the 2009, 2010 and 2011 CNGS data was carried out to measure the neutrino
velocity. The sensitivity of the measurement of (v-c)/c is about one order of magnitude better
than previous accelerator neutrino experiments. 22
The results of the study indicate for CNGS muon neutrinos with an average energy of 17
GeV an early neutrino arrival time with respect to the one computed by assuming the speed of
light in vacuum:
δt = (60.7 ± 6.9 (stat.) ± 7.4 (sys.)) ns.
The corresponding relative difference of the muon neutrino velocity and the speed of light
is:
(v-c)/c = δt /(TOF’c - δt) = (2.48 ± 0.28 (stat.) ± 0.30 (sys.)) ×10
-5
.
with an overall significance of 6.0 σ.
The dependence of δt on the neutrino energy was also investigated. For this analysis the
data set was limited to the 5489 νµ
CC interactions occurring in the OPERA target. A
measurement performed by considering all νµ
CC internal events yielded δt = (60.3 ± 13.1 (stat.)
± 7.4 (sys.)) ns, for an average neutrino energy of 28.1 GeV. The sample was then split into two
bins of nearly equal statistics, taking events of energy higher or lower than 20 GeV. The results
for the low- and high-energy samples are, respectively, δt = (53.1 ± 18.8 (stat.).) ± 7.4 (sys.)) ns
and (67.1 ± 18.2 (stat.).) ± 7.4 (sys.)) ns. This provides no clues on a possible energy dependence
of δt in the domain explored by OPERA within the accuracy of the measurement.

Actually, I thought Zichichi's comment about extra dimensions made it so relativity would not be violated. As light would still be travel in spacetime, not hypothetical string theory dimensions.

Nonetheless, maybe he was just over excited.

So a superluminal velocity has been detected. And all the news sources are proclaiming that Einstein’s special relativity is wrong. I don’t think so. And there is no other device that is accurate enough to verify the claims. Could this be another cold fusion fiasco? Although I abhor general relativity, I totally support special relativity. It will take a lot of convincing results for me to accept this.

it was 16,000 separate events with an accuracy of 2 cm in the distance. It is very unlikely:

A key feature of the neutrino velocity measurement is the accuracy of the relative time

Septentrio PolaRx2e [16] operating in “common-view” mode [17] and a Cs atomic clock
Symmetricom Cs4000 [18], were installed at CERN and LNGS (see Figs. 3, 5 and 6).
The Cs4000 oscillator provides the reference frequency to the PolaRx2e receiver, which is
able to time-tag its “One Pulse Per Second” output (1PPS) with respect to the individual GPS
satellite observations. The latter are processed offline by using the CGGTTS format [19]. The
two systems feature a technology commonly used for high-accuracy time transfer applications
[20]. They were calibrated by the Swiss Metrology Institute (METAS) [21] and established a
permanent time link between two reference points (tCERN and tLNGS) of the timing chains of
CERN and OPERA at the nanosecond level. This time link between CERN and OPERA was
independently verified by the German Metrology Institute PTB (Physikalisch-Technische
Bundesanstalt) [22] by taking data at CERN and LNGS with a portable time-transfer device [23].
The difference between the time base of the CERN and OPERA PolaRx2e receivers was
measured to be (2.3 ± 0.9) ns [22]. This correction was taken into account in the application of
the time link.

If you guys want to pursue a tachyonic explanation, that's fine with me. But I'm not convinced. I'm wondering what the measured velocity versus kinetic energy graph looks like. Does it look like the neutrino velocities are all approaching some particulary velocity? If that were so, I would suspect that they were really approaching c, but for a mistake somewhere. Or do the neutrinos seem to ignore the existence of a maximum velocity, as if they were immune to the invariance of c.

Who has the facilities to duplicate this experiment?

Actually I don't yet know much about the experiment. You smash particles at CERN to create a pulse of Neutrinos. Some are than detected at San Grasso. They take the distance, divide by the time between the events then say they got a speed greater than c. I would need to know more about how the times are determined between the creation and detection events and how the clocks are synced in order to accept it. Essentially they are claiming to have two clocks 730km apart synced withing 10ns and more amazing, that they can determine the time of the creation event and the time of the detection events to within that much time for error. I wouldn't call neutrinos as Tachyons new science as such as model has been around for so long. I would call it fringe science. The theoretical framework is already in place. This is why they went to do this experiment and why supernova neutrino and light reception times have been compared in the first place. There was some suspicion that this may be the result in the first place.

Crazy .... been doing some basic calc's regarding CERN's faster than light neutrino data.
Supernova 1987A was responsible for a neutrino surge 18 hours before any optical confirmation.

CERN to Gran Sasso = 732km ..... neutrino's arrived 6 x 10^-8 sec's ahead of predicted c
Supernova to Earth ... around 160,000 light years (42 x 10^13km)

Well oddly enough, 42 x 10^13/732 x 6 x 10^-8 = 18.82 Hours!!

while i disagree with your evaluation of the importance of the paper or of the journal nature, and i find your comments about the paper, antiquarian at best, is not a topic worth even arguing over.

i do agree with your assessment of the ridiculous quotes about the CERN neutrino experiment.

It has been glaringly obvious that experimental/theoretical science has been pumping money out of the NSF for quite sometime to test theories that should have been round filed a long time ago. The current theories are very specialized, difficult to understand, and error prone, which unconscionable people use to their advantage for monetary gain.

Actually I don't yet know much about the experiment. You smash particles at CERN to create a pulse of Neutrinos. Some are than detected at San Grasso. They take the distance, divide by the time between the events then say they got a speed greater than c. I would need to know more about how the times are determined between the creation and detection events and how the clocks are synced in order to accept it. Essentially they are claiming to have two clocks 730km apart synced withing 10ns and more amazing, that they can determine the time of the creation event and the time of the detection events to within that much time for error. I wouldn't call neutrinos as Tachyons new science as such as model has been around for so long. I would call it fringe science. The theoretical framework is already in place. This is why they went to do this experiment and why supernova neutrino and light reception times have been compared in the first place. There was some suspicion that this may be the result in the first place.

I think somebody made a big mistake and the error bar isn't going to be 10ns or less.

Debunking the likes of Sir Issac Newton, Einstein, my Science teachers, I bloody well will have to do better than the preceding.

We have been led to believe that thunder is the after math or results of lightning when in fact the opposite is true!

Thunder (the collapse of air cells) creates the energy of what we call lightning.
Thunder happens first!

Sound travels much faster than light !

The sound that we play around with is leftover energy of reactions that have magnetically regrouped into larger chips (molecules). This leftover energy is just one in many that an air cell has as it’s nucleus!

I’m glad you pointed this out although I doubt it will sink in with most. Unfortunately this is a behavior that seems to be ingrained in human thinking, at least since recorded history. We see what we want to see, make absolute conclusions with little evidence, ignore or use convoluted rationalizations to dismiss evidence that indicates our position is flawed or wrong, and form most opinions (and arguments) based on what is in our own self-interests (financial, stature, ego, spiritual, etc).

This is rampant everywhere including this forum, and most people believe this to be true of others but not themselves. I am most disappointed when I see people devoted to the sciences do this, and unfortunately they do it too. I would say the three biggest factors for this behavior are laziness (as you pointed out), ego, and financial, in that order. We all have this tendency including myself; even though I make a constant effort to avoid behaving this way on reflection I still don’t avoid it entirely. This is why I try to be more tolerant of others when they do it. It seems to be ingrained in our genetic makeup.

Hi Professor. I agree with your assessment of shady research. In this case, we are questioning the validity of the CERN measurement of the superluminal velocities of neutrinos. It’s a hot topic. Thus this one has generated some overheated discourse. I do not see an end to the controversy for quite some time due to the many possible sources of error. Perhaps it is safe to say that, “We done plowed up some kinda snake.”

Actually my information is starting once more to disseminate just fine like it or not, and whether you know it or not. The next couple of months will be exciting for me. There's a reason things are happening like foreign professors translating and pdfing Modern Relativity into their own languages, like MIT adding it to multiple sections of the Net Advance of physics etc. This all started to happen a decade ago, but I made the mistake of changing the domain name over to a free server, geocities which later went out of business.

100% true experiment and theory of relativity is also true 100% is not uncommon here at all


*why such conditions must be recalled before the experiment was conducted
*1) make sure they only have one way to find the particle velocity is distance divided by time taken to measure time. Calculate the velocityies they do not measure the velocity of all particles in the air the moment it (more specifically they do not measure its velocity in each fraction of the distance).
*it so it will have a certain time to obtain the right with 300000km / s and to the state "teleport" to all the remaining distance so that when the average speed will be the same.(In general relativity have mentioned problems when traveling with 300000km / s, the time will stop. That's the phenomenon is referred to teleport)
*said base is so still have to explain more intensive use of quantum theory. and the fear that a few dozen pages to explain, not jokingbecause the article did not specify the conditions under which experiments are difficult to make but specific analysis. entropy can be used to explain this phenomenon is very reasonable.that is certainly not all fires are 15,000 particles reach the velocity that is only a number but a number will reach speeds under 300000km / s (entropy is what is on google search will)

'91 '92 somewhere in that time frame. Yes but it's been a long time ago. /I don't know if i still have them.


Do you have knowledge in neuroscience?

Yes mostly focusing on axon firing and the binding problem and mostly as it relates to simulated AI in multi-entity simulations. My wife is a neuroscientist however and smacks me around a bit with theory, I enjoy the conversations, i am by no means an expert in the field.

Really? I'm currently reading about the cortico-basal ganglia-thalamocortical loops. It helps my atheism... wink.gif Do you have any good references?

Speaking of references, is scholarpedia bad or good? I haven't had time to go through it.

Can you answer my question about the neutrino group velocity?

WТF? Why does everyone always ignore my questions? Are they that dumb? huh.gif

Okay...anyone? What should the difference between the phase and group velocity be for neutrinos?

AND is scholarpedia a bad reference?

Since most responses are fighting or insults you should probably take it as a compliment that you don't get a lot of responses.
For any particle massive, massless, imaginary mass the phase velocity is
v = ω/k = E/p
and the group velocity is
v = dω/dk = dE/dp
we have
E˛ = p˛c˛ + m˛c⁴
and differentiating you get
dE/dp = pc˛/E
so you could just as well say the group velocity is given by
v = pc˛/E
As for your site, yes anything be it wiki, your suggestion, Modern Relativity, or whatever is bad for just asserting as reference quote. Nothing but actual demonstration and explicit derivation should carry any weight in scientific discourse. I haven't looked at it, but my bet is that just like any text material there will be portions of it that are right and portions that are wrong. If you're interested in the subject you have to actually work through the math and evaluate for yourself everything's validity to be certain of it.

So, negligible like 10^-19 for neutrinos, right?

Thanks but I've had my far share of insults. Besides, it's only a wee little question, not a theory.

Goodnight...Zzzz

Besides the vicious criticism you emanate, please point to one original idea that you have submitted to this forum.

Ideas should be connected to the physical universe.

Yours are not. You take the view that if something is 'new' it must be worth consideration, whether it has any foundation in the physical world or it doesn't.

The science of physics isn't something that was just made up. It is a very accurate description of how the universe operates. If you're going to propose something which runs counter to this very accurate and extremely well tested description, you have to supply something more than empty speculation.

Have you submitted any new ideas to this forum? And you say my ideas are not connected to the physical universe? Who can judge whether a new idea has any foundation in the in the physical world? I agree that the science of physics isn’t something that was just made up. But can you determine if a new idea is empty speculation? When presented with arguments that I believe are not unfounded, I recant. I’m flexible and willing to take the heat of criticism when proposing new ideas.

You mean have I made up any empty ideas? I don't think an uninformed imagination is an asset in science.

When you ask who can judge if an idea has any foundation in the physical world, you show that you're uninformed regarding the last hundred plus years of experimentation and observation. If your new idea doesn't agree with what is already known to be fact, then you must supply extraordinary evidence to support it. Not 'wouldn't it be neat if...'.

While you tout your willingness to 'recant', it would be better if the ideas had some foundation in the first place.
