[quote:Anonymous Coward 27168996:MV8yMTAzMjU2XzM1NDQ2MjczX0VCQkE2QzFF] time would not stop at absolute zero, because while atomic motion stops, other processes remain such as the spin of subatomic particles, or the "movement" of electrons due to the fact that, while they don't actually orbit an atom, they have certain probabilities of appearing at given points, due to quantum mechanics. even a mile away from an atom, an electron has a certain infinitesimally small probability of appearing for a very brief period. or on the other side of a lead wall. due to those mechanics, [i]no[/i] barrier is truly impenetrable. thus, the electrons are going to "move" no matter what. the implications of that are very, very interesting. 1) say one molecule, at absolute zero, a crystalline state of zero-point energy, is all the universe consists of. all motion stops except the spin of subatomic particles, and quantum fluctuations ("movement") of electrons. yet nothing affects them and they affect nothing- practically speaking, it's an absolutely perfect top that spins forever and ever and ever. so, in that universe, time exists- yet has zero effect whatsoever. what good is it? doesn't that mean time ceases to exist? yet it does exist. 2) doesn't the fact that many such molecules interact together in a relative time frame, mean that the entire universe should by definition be considered one big molecule? [i]because of time?[/i] [/quote]
