Why can't you argue physics with someone who said they physically went back in time?

If there were no proof on either side, then you just proved that this guy didn't go back in time. If he did it, he would be able to prove it.

As far as proven physics (as in proven physically, rather than with 'just' math), it would seem possible that one might be able to travel back in time, but far too unlikely for humans to ever reach that goal.

You're right, things may be disproven in the future, but don't say that the formula E=mc^2 isn't physically proven. Aspects of it might change, but if it weren't truth, atomic bombs wouldn't exist. That's physical proof for you.

Time dilation is fact as well. So is the fact that a massive object can not travel faster than the speed of light. If it were to do so, a singularity would occure.

By me saying that no massive object can travel faster than the speed of light, I mean that this object wouldn't exist in our physical world the way we do if it were to happen. Black holes have proven this for us.

Anyway, there is proof on either side that time travel might, or might not be, possible, but for humans, it's proven that it's more than likely (as in you would have a better change of winning the lottery 234235234235 times in a row) that it is impossible.

Now, you could go and argue that all math or all physics may not be true, since we only have this little portion of the universe to test things, but that would just be silly. Physics holds truth higher than your thoughts on things, since many people have put a lot of thought into the science, and have proven them to be physically true for many situations. Once you go and prove them to not be true, I'll regard your thoughts as being more valid than what I have learned through the scientists that have done the leg work.
