Does the expansion of the Universe equate to the forward movement of time?

Question

Such as if the Universe contained above the requisite mass, the Universe would eventually begin to contract, would that contraction reverse the forward movement of time?

Did time begin or the forwad movement of time at the Big Bang

Answer 1

Time is not a *natural* feature of the universe. Time is nothing more substantial than a concept developed by sentient beings like us to separate events. Imagine that we traveled from point 'A' to point 'B' at some specific velocity and measured the time for the trip. That time, as measured by whatever standard we use, is dependant upon how fast we move and how much space is between 'A' and 'B.' If we waited a few billion years and made the same trip at the same speed again we would find that it takes a tiny bit longer because during those few billion years space has expanded. On the other hand, if space had been contracting during those billions of years the trip would take less time. The important thing to realize is that the difference in times is based strictly on our standard of time, which for our species is set by the radioactive decay of cesium atoms. Time is not set by some Cosmic Master Clock.

I dont think so. Time exist reguardless to movement or matter
