# Does time freeze at Absolute Zero? [closed]

Time has many definitions per se, but the basic idea being it's "the measurement of change" so as we know, all matter looses it's ability of changing with the loss of kinetic energy. and the where it becomes zero is the absolute zero (−273.15°C). so my question would be, will time stop/freeze at Absolute zero? and does time get slow while reaching there?

• What does "time stops/freezes" even mean? – ACuriousMind May 12 '15 at 16:46
• and also, stuff doesn't really stop moving at absolute zero. Things still have Zero Point Energy. – Hritik Narayan May 12 '15 at 16:48
• @ACuriousMind I don't know any technical term, but you heard me once. it means to stop the changing happening. – AACaN May 12 '15 at 16:52
• @HritikNarayan i need to read more about that. thanks. so this Zero point energy may still cause changes in matter??? – AACaN May 12 '15 at 16:55
• The basic idea of time is that is is one of four dimensions in spacetime. The fact that it seems to be related to change or entropy is fascinating, but as far as we know that doesn't rise to the level of a definition of time. – Brionius May 12 '15 at 17:12

Time is just a coordinate like the spatial coordinates, that is we label spacetime points with four coordinates $(t, x, y, z)$. Indeed, in relativity (both flavours) the time and spatial coordinates get mixed up so different observers will disagree about what is time and what is space.
