yes, because of time dilation. If you leave earth in a spaceship that travels close to the speed of light you might return to find that 20 years have passed on earth while you only spent, say, 1 year on the ship. you've travelled into the future!
the catch is, you can't travel back into the past, like maybe 19 years to the "real" time you were supposed to land. (no such thing as "real" time anyway - it's all relative).
for now, it's widely agreed that travel to the future is physically possible by time dilation, but as for travelling to the past scientists are still divided on whether the physical laws actually allow for it.
It depends on how you define time travel. What you see in the movies where someone goes back in time is impossible. But, if we ever get very fast space craft and make round trips in them the space traveler experiences what we call the twin paradox from the effect of special relativity. Her internal clock slows down depending on how close to the speed of light she goes and after she has completed a trip of say 20 years she could find that 30 years have passed on the Earth.

There was one scientist who has a workable theory. Many scientists say that it is possible. I saw this on a documentary once but I forgot the title.

nope because time doesnt move forward or backward
time is relative to surroundings so time travel is basically impossible (atleast in our universe :)
Absolutely, but you're gonna need a DeLorean.....
not as far as we know.
