I was thinking time is just change in matter. So theoretically if something was cooled to absolute zero would time stop for it?

well pardon me for using logic.
if something is being squeesed, it will heat up. that is why suns are hot.
black holes having gravity so strong not even light can get out, would surely there for have the same effect.

i mean what the singularity (sp?). if everything is broken down and made into one giant (pea sized, i hear) atom/molecule, 1 atom/molecule can't rub against its self. so that means no friction.

It should be noted that molecules still vibrate at absolute zero with what is known as zero-point energy, it is impossible to completely 'freeze' something (as indeed by thermodynamics it is impossible to reach absolute zero).
Black holes do have a property called 'temperrature' and it's simply a measure of the amont of blackbody (i.e. Hawking) radiation they emit. ...[/B]
Absolute zero is the lowest possible temperature, at which all molecular motion ceases. It is often expressed as 0 Kelvin, or -273.15 degrees Celsius.
No, time does not actually stop at absolute zero. However, at this temperature, all molecular motion stops, and time appears to stand still. This is because time is closely linked to the movement of particles, so when there is no movement, time seems to stop.
According to the laws of thermodynamics, it is impossible to reach absolute zero as it would require an infinite amount of energy. However, scientists have been able to cool certain substances to within a fraction of a degree of absolute zero.
The concept of time is closely linked to the movement of particles. As mentioned before, at absolute zero, all molecular motion stops and time appears to stand still. Therefore, absolute zero is often used as a reference point for measuring time in certain scientific experiments.
Understanding absolute zero and time has many practical applications, particularly in the fields of physics, chemistry, and engineering. It allows us to better understand the behavior of matter at extremely low temperatures and helps in the development of technologies such as superconductors and cryogenics. It also provides a valuable framework for studying the fundamental laws of nature.
