Will time travel ever be possible?

I don't care if you focus on one or all of them, but any answers are appreciated! These are about time travel, with a focus on traveling BACK in time... 1. Will time travel ever be possible? 2. If so, how soon? Also, how far back would we be able to travel? 3. Would our bodies be able to survive time travel? 4. Would time travellers be able to communicate with other humans, or would they be on a seperate plane of time/dimension? 5. Is it possible that spaceship sitings are time travel machines from the future? Also, if anyone can answer #4 (at least in theory), I'd be grateful.
