For all you thinkers: does time exist at "absolute 0"?

Question

I may be wrong... but isn't time just a sequence of events? at absolute zero nothing can move therefore there are no events to sequence so could time exist?

Answer 1

The trouble with just thinking about basic physics is that it's too easy to jump to conclusions. Here's one example:

1) Things move more slowly when it's colder
2) At absolute zero, things stop moving
3) If nothing's moving, time must be frozen; i.e., time ceases to exist

All right, let me tell you what's wrong with that picture. Quantum theory says that it's not possible to simultaneously have

1) EXACT location, and
2) EXACT momentum

If at absolute zero, something is absolutely not moving, which means it has an "exact" location AND "exact" momentum (namely, exactly 0), that's a violation of the Heisenburg Uncertainity Principle. Check the link to an article that talks a little about this.

Because 2) cannot be true, then 3) doesn't follow, and time exists even at absolute zero.

Answer 2

Well, most physicists consider the whole of spacetime as a frozen river, as if its all happened - its just our consciousness drifts along like a movie being played - all very speculative but your question isn't hard to answer because of that - time isnt a sequence of events - you're talking about human perception and interactions of matter - absolute zero means minimal (there is still some movement - quantum effects make particles jiggle about a bit) movement - you might as well ask if there is no space at 0 kelvin.

Time isnt effected by temperature at all.

Answer 3

An interesting question. Although, as one person has already pointed out, you couldn't observe absolute zero without ruining it anyway, I think you could safely say that time wouldn't exist. This would occur because time is the result of entropy, which is the process of all the energy in the universe being turned in unusable heat energy. If there is no heat, there can be no time because this change cannot occur.

Answer 4

It sounds like you are confused about just what happens at absolute zero. Not all motion stops at absolute zero. Electrons still 'orbit' and molecules still vibrate so if you measure time by things moving nothing stops you from being able to do this.

Answer 5

I don't think it's a "sequence" it's the difference between the things happening.

But of course, to obtain absolute zero, someone must be doing it, and time would pass for them, and the item w/ no energy too.

Answer 6

Interesting question. Absolute zero is a moot discussion, since any observation of a system at absolute zero would impart some miniscule energy to it, raising its temperature slightly.

Answer 7

if time is a sequence of events then time would not move untill ''absolute 0'' changed.
so we would'nt even know if it happened or not

Answer 8

Time is really a thing that man invented. Time still moves on even at abs zero. Its based on the celestial movement of the planets ( day and night) time (accurate) is based on the atomic vibration of cesium, hence the cesium time standard (US Navy). accuracy and precision are not the same thing. older time standards that were/are eclectronic in nature used quartz crystals in temp regulated ovens..all very fascinating. Go to Google/ U S Navy time...this is very cool!

Answer 9

Time may be invented by man, but the perception of things changing(Time) is real.

Hence when you put a clock on top of a tall tower on earth, and one on the bottom, the one on top will run a little slower than the one on the bottom.

wow..ok right here's the component it truly is what i have self assurance is ideal and incorrect: good: Accepting human beings for his or her judgements and how they prefer to stay their existence incorrect: Judging human beings earlier you even choose your self... good: helping human beings even as they ask for help incorrect: Shoving your faith down different peoples throats assuming that they prefer help good: Being mature and admitting once you already know you're incorrect incorrect: Plugging your ears like slightly baby even as someone is making an attempt to describe their reviews to you actually i do not desire an expert to inform me what's ideal and incorrect...How did you already know what's ideal and incorrect? merely because a e book is telling you techniques to stay your existence perhaps it truly is a adulthood component yet i come to a decision to be a strong human being i do not desire an expert to threaten me to be a strong human being...possibly you do which i stumble upon quite unhappy yet perhaps sometime you'd be able to strengthen up!! i love who i'm i understand who i'm perhaps it truly is time you commence determining who you're instead of being insecure and judging human beings:) morality is subjective it would not come from a freakin e book
