Questions for PhysOrg

1: Does measurement of distance have a minimum amount?
By this I mean, is there a smallest distance.

2: Same question for time...
Is there a smallest measurement of time?

3: Are there infinite colors?
If the answer to question 1 or 2 is yes, then this question's answer is probably no...
right, otherwise this would be yes...? no?

4: Is color 4 dimensional?
This question's a little vague... Uhh...... I know what I mean, but do you?

5: Explain, or give a good reference to, what exactly are dimensions, and how can we know they exist beyond our comprehension.

6: String theory?
Another question asking for explanation, or reference...

5,6 - Google is great, but with the millions of results that come up, some times it can be a little bit overwhelming... especially when you really don't know EXACTLY what you are looking for, so please don't just point me to Google!

7: Can anything ever be truly random? If we knew exactly how everything worked, would anything be capable of having a random result, uninfluenced by any factors? A bit of a paradox, but let's work around that.

1: What causes death... Rather broad I guess... let's narrow it down. What causes death beyond disease, injury, poisoning, etc. What causes someone to just drop dead after x number years of life? Why don't the cells in our heart just continue reproducing at a continuous rate forever? Why does the skin slowly become wrinkled and stay that way, instead of just repairing itself? I will attribute all of this to sunlight, but I know that can't be so... that would suggest that living in a UV ray free area all of your life would result in immortality...

1. most of us would say no, StevenA and Precursor can't think abstractly so they would say no.

2. see above

3. see above but switch no and yes

4. not sure what you mean

5 Buddha

6. They keep my shoes from coming off

5.6 The people who know of what they speak say stayeth thou away from Google.

7. Einstien said God does not play dice with the universe. Someone else told him not to tell God what to do with his universe.

1. when cells reproduce they lose DNA from the ends. Some people say that death is programmed in.
I read that almost all mammals have roughly the same number of heartbeats in a an average lifetime. Except humans who have three times as many as an average mammal. But that could be complete BS.

Thanks for all the help. err, kinda.

1: Does measurement of distance have a minimum amount? By this I mean, is there a smallest distance.

no

2: Same question for time...Is there a smallest measurement of time?

no

3: Are there infinite colors?

there are a finite amount of colours we can percieve. you can not count an infinite amount of anything

4: Is color 4 dimensional?

colour requires a dimension of time since colour is the emission or transmission or reflection of light. these processes involve change. you could have colour in 2+1d ie 2 spatial + 1 temporal

5: Explain, or give a good reference to, what exactly are dimensions, and how can we know they exist beyond our comprehension.

any of the basic physical quantities, such as mass, length, and time, from which other quantities are derived http://cnx.org/content/m15037/latest/

6: String theory?

whatever AlphaNumeric says is probably most true, since he is an actual string theorist. to me "an attempt at the construction of the most fundamental physical framework of everything"

5,6 - Google is great, but with the millions of results that come up, some times it can be a little bit overwhelming... especially when you really don't know EXACTLY what you are looking for, so please don't just point me to Google!

i consider the creation of the universe a random event, since i think there was no preceeding cause.

no thing can remain unchanged in the universe. for the same reasons perpetual motion is not possible, no thing can remain unchanged.

fair enough.

to me whether its a branching universe or a unique universe

Dr Adrienne Erickcek, and colleagues from the California Institute for Technology (Caltech), now believes these fluctuations contain hints that our Universe "bubbled off" from a previous one.

Their model suggests that new universes could be created spontaneously from apparently empty space. From inside the parent universe, the event would be surprisingly unspectacular.

to the parent universe and what is the response?

the bubble universe theory relies on a universe, not necessarily the one we are familiar with as having always existed. for me, the idea of nothing>something is more understandable than always something

I must agree with this, but I have a hard time wrapping my mind around either of those concepts.

On the subject, I remember reading, or seeing, somewhere that if something (I believe it may have been Helium) could be cooled to absolute zero, it would become frictionless, and would be capable of produccing a perpetual fountain... Links? Input?

Ok. Since I'm not thrilled with any of the answers you've gotten so far.

1. Yes. Zero is the smallest measurement of distance without going negative.
2. Yes. Zero is the smallest measurement of time without going negative.
3. Yes. Contrary to your assumption that yes answers to 1 and 2 mean no here.
4. I cant answer that.
5. I cant answer that either.
6. I cant answer this either.
7. Yes. Plenty of things are random. The first practical example that comes to mind would be a random mutation of DNA. Such a random mutation would be a result of the position of the gene in space with respect to the path of a gamma ray that inflicted damage on the gene. Someone may argue that they can know the position of the gamma ray and the gene beforehand and I suppose I wouldn't argue that they couldn't know it in advance (perhaps through some statistical math predictability "thingy"); however the reality of the actual occurrence leading to the genetic damage is random. I would think Chaos Theory would be something to read up on with regard to such effects. Sometimes there are just too many indeterminate parameters affecting the system to allow prediction.

New 1. Everything wears out/dies/decays ... except protons (possibly).
