In the theory of the big bang scientist claim that before it, time did not exist. They claim that if there was a big Crunch... Time would stand still between it, and the next Big bang. But time is an illusion. It is as 'flow' to the movement of a river. It is a description of the interactive continuum of the particles that are the universe. These are unceasing as a static state does not exists. Particles interact not in 'time', but in space.

There is no future, there is no past. All that there is, is the ever changing state of particles.
