it's not exactly time, but preferably dimensions. cuz wormhole does exist, but in a subatomic levels, which is why some scientist find subatomic particles pop in and out of existence. cuz they go through tiny wormhole to another dimension. so if we can create enough energy to rupture space, and create a black hole, than it is starting point in time traveling

Yes, it is true. However, the technology required for such a feat (considering the exponential progress of science) is AT LEAST 1000 years in the future. So.. Don't hold your breath.

Not really, if humans could ever travel back through time then we would have visitors from the future.

Only if you travel through God's channel.

maybe. some people think so, but nobody knows for sure. don't try it, because you have no way of knowing if you'll travel through time, travel through space, of just get smooshed into nothing :)

In theory, yes.
