could time travel exist in the future?

Well, time is physical, we know that much from nuclear clocks, one set on Earth & the other in space were a trillionth of a second different

But...with gravity, comes more "stopping", and clouding up the way

Like that the Big Bang theory

Even if it happened, how?

A ball, of everything in the universe packed down to the size of a marble

1. Where'd it come from? Another universe? Where'd that come from? Where is the ORIGINAL starting point for all the continuum universes?

And

2. How did it explode? Did time exist before the Big Bang? If so, then the Big Bang isn't the origin.

If Time Travel existed, why haven't we met anyone from the Future?

Regardless, I think that if Time Travel becomes possible, it should be restricted in the sense that you can go back in time to view the past, but it'd be like a movie in a sense that you can only watch instead of being able to alter events in the past.

It's physically impossible to thwart time and minimize our cells to the smallest particles so that we may travel through certain dimensions of time with our body fully I'm tact. This is just entertainment, a fantasy if you will. Even if this fantasy was real, which it isn't, my hypothesis would be that they wouldn't want to alter the past that could damage anything in the future that could be vital.
