Hey, i was just wondering, time is define by mouvement. So, if there is no mouvement of atoms at the absolut 0 and not even the atoms can move, wouldn't that mean that time would stand still?

yes

Nope, it's often measured by movement, but your claim is like saying I don't have height if I don't have a ruler.

not OP, but thanks for the site, it's pretty neat

for me this is mouvement.
and thanks for the website!

What part of "it's often measured by movement" are you missing?

This whole page is talking about measuring time by observing movement.
But since time (presumably) exists even when it isn't being observed, their point is moot.
It's like saying the space between atoms doesn't exist because there's nothing there.

time is defined by CHANGE not necessarily movement.
>>7692027
So if there is no change due to it being absolute zero there would be no time in that area, correct?
>>7692027
I fail to see the importance of this distinction. How can change be anything but movement? How can anything change without movement? What I'm trying to say is, isn't change the exact same thing as movement?

Can we measuring time without observing mouvement? i mean if we can't see mouvement in a vidéo it will change to a photo, and in a photo there is no time.
Isn't a good analogy?

But time still exists even if you don't measure it.

A particle that slows down toward zero velocity would have a very well defined position and therefore an undefined momentum, making it impossible to actually reach 0K. It's impossible to get rid of motion.
