Special Relativity. Lifetime.

[Alex K]

Time pops up a lot in any physics discussion because it's one of the basic dimensions in which we exist. It's exceptionally difficult to describe our universe without bringing time into it, so yes, it pops up a lot in physics.

I question whether time exists independent of a mind, but I suppose I don't know enough about the physicists view to argue against it at the moment.

Whether time exists independent of the mind or not, I don't even know exactly what that means. All I can tell you is, compare any two physical processes at relative velocity v to each other, with appropriate clock synchronization beforehand, and you will measure exactly the discrepancy in their rates as predicted by f'=f* sqrt(1-v^2/c^2).
