History abhors a paradox.....

It is this paradox that leads me to believe that time travel will never be possible.

Time travel is not only possible its inevitable.
Mathematics have absolutely nothing to do with this. Travel forward at a rate differing our own has been stated again and again.
The issue is with traveling backwards in time. That is where the paradoxes come in.
Think about it, you can travel all you want as long as it is always from past to future you have no danger of a paradox.....
backwards is the issue and that is debatable about whether that can happen.

I respectfully disagree that travel in time (forward and backward at will) is NOT possible.
Read Kip Thorne's conjecture about fishing 2 wormholes out of the quantum foam, enlarging them and holding them open with exotic matter (and negative energy), moving one relative to the other at close to the speed of light away from each other and then back again, jump in one, come out the other in the past! You can only travel as far back in time as to when the time machine was created to avoid the classical time-travel paradoxes.
To travel fast(er) into the future, just zoom your spaceship real close to the event horizon of a black hole.
Simply an engineering problem, what with exotic matter, negative energy, quantum foam fishing and zooming up to black holes!

The thing about time travel is. . .
You most likely would not be traveling through "time"; instead, you would be traveling to a universe that would be similar to the "time" that you are traveling to (for example, if you wanted to visit the landing of the Pilgrims, you would go to a universe where the earth existed under the same conditions and where humanity had progressed the same amount).
Each universe exists seperately; you leaving a universe and going to another one (if possible, which we really don't know yet aside from harnessing impossible amounts of energy) should be no different from you leaving a building and walking down the street to another building. . .of course, you would have to worry about what physical laws govern the universe you are traveling to (and even that might not be true; IIRC, we don't even know if parallel universes actually exist or not).

The solution to that paradox is simple:
We would keep fiddling with the past and create a new present . . . until we finally manage to creat one where time-travel is impossible.
So, time-travel MUST be impossible! No paradox.

time travel would be the most pervasive force in the universe.
It would disrupt the course of the universe such that it could not exist.

i do not believe in time travel, it would just mess up every thing, so there are no such thing as past and present selves, though i do believe in past live and reincarnation

We are all time travelers. Just happens to be forward and all at the same speed. ;-)

Time travel is not possible. mathematics does not allow that this be permitted. It is a moot point.
