Is time travel possible theoretically ?

This subject is done to death in a number of threads, however there are still various points to make.
For instance one of the many misconceptions is "If you could travel faster than light, you'd end up being able to go back in time." That is a ridiculous notion, after all it isn't talking about two competitors racing to a finish line where if one runs faster will finish first. What you are actually assuming is that the fast at which you travel, the slower the universe will be as a counter observation to you. It doesn't mean the other competitor starts running backwards slowly, what it means is the fast you travel the closer you'd get to a universal state of "Rest" or absence of motion.
If you kept going until everything was at absolute rest, everything but the person attempting the observation would cease to exist.
It does generate an important question in regards to what occurs should "you attempt to return to normal speed", as if you reached that ultimate universal absolute rest, you will have broken "continuity", so you might never be able to return back to a normal universe. It generates a rather interesting discussion in both Philosophy and some area's of Theology considering such figurative's like "Maya", after all to exist in an occurance of absolute rest is a potential "space" to build a whole universe from scratch, "a beginning". While going to the point where entropy becomes so great that continuity can no longer follow suit is itself a form of universal destruction, "an End".
So it's figuratively a beginning and end, while also being a completely figurative illusion.

Forward time travel is. Traveling back is problematic in many ways- and on a logical level, not just on the level of application.
If in a "different universe" where causality wasn't a problem, perhaps then. Traveling back in time outside one's own sphere of causality is also potentially acceptable.
