  :I understand the idea that change creates time, and I agree with it in a certain way. If space and time cannot be extricated from each other, the flow of time can be thought of simply as a kind of change, with little difference from simple motion. I would have little problem with stating that time itself is a name given to a certain kind of change. (Of course we would need to *source that - do you know of any?) But even beneath that level, there is the issue of whether change - any kind of change - requires something called time in which it can occur. Doesn't change require time? Hence you might start to understand the idea of dimension, and how its not invalid. That's not to say that we truly understand time yet - we understand holography now - perhaps time is simply a kind of computation, a la digital physics. -  |
