Can the Universe Travel Faster Than Light and Time Travel?

[arcbishop]

will acceleration and expansion cause the universe to travel faster than light or a critical state to where itself travels back in time.
if so would it be able to stop if it crashed into something big as it self (big bang)?

I have no idea what you mean by the universe "traveling". Where is it goiung?

Pretty nonsensical question. The universe doesn't travel, things IN the universe travel. None of them exceed the speed of light, although they do travel faster than the speed of light RELATIVE TO EACH OTHER.

Since our current model says there is no "outside" to the universe, the concept of it crashing into something is just silly.

You really need to do a lot of basic reading to get some understanding of this stuff.
