Absolute Zero and Time?

  1. Feb 23, 2008 #1
    (i have next to no knowledge about physics so please don't beat me down my there are flaws in my theories)

    as they say, time is defined by movement. you might say, "my eraser is perfectly still in my freezer (why you would put it there is beyond my comprehension)" be we are still moving on tectonic plates, when we are asleep blood circulates through our system and so on, but absolute zero (estimated at around -273.15C and further, and is not physically reachable) is when atoms are estimated to have the lowest amount of energy. I ask, (in theory) if it got so cold to a point where there was no more energy (i estimated at -546.3 C...double absolute zero) would it no longer exist, since time is defined by movement, and as it has no energy therefor movement?

    Who says that? It's wrong.

    Time is used to quantify the motions of objects, it is not defined by the motion.

    "I ask, (in theory) if it got so cold to a point where there was no more energy (i estimated at -546.3 C...double absolute zero)"

    A system with negative absolute temperature is actually hotter than any system with positive temperature. You're going to have to clarify what you mean here.

    Absolute zero, by definition is the "temperature" at which no movement exists relative to any thing.

    Does'nt the scientific method break down at absolute zero, and therefor it being pointless to question the logic of a situation therein using said method?

    You could say that "As we approach.." and "It appears.." but any information about that point can never be known with any certainty.
