Saying time travel is possible using a fictional device is not really on topic.

to this point if you know that whatever effect you could have on history would have already happend. why would you go back in time to try to make a change if you already know what the outcome what be.
time travel will always bring up the ? of free will. for history to be predefined that also meens that the future must predefined (allowing for time travel). that where paradox come in a system that is not predefined then you can change history in a way that will change the future from that point on.
the ways around this have already been put down in this post but have been decided that would not count as time travel becuse it is not your past.
if it is the case we have no real free will and everthing that can happen has happen and time travel is passable the only reason I see people using the thing would be to go back in time is as site seers. im sure people would still try to change things some times.
I think this has been ontopic mostly save a few people I will not name. (points at Icarusbop)
