There is one reason I know time travel will never exist - if it did, someone would have already traveled back in time and told us about it. That is of course if multiple timelines don't exist and the guy who traveled back in time went to a parallel timeline and not this one. Yes, it is very confusing, but that is the only explanation as to why we don't know about time travel from a guy from the future. Then again, if I had time travel, I wouldn't tell anyone and would just travel back in time, get some great stock tips, and then profit like crazy in the future.
But let's say you do travel back in time and talk to one random person for half an hour or so, what do you think the repercussions would be? Just by talking to that one guy, he might miss a date with his future wife, she dumps him, causing random people to never be born, changing all sorts of other future actions to never happen, which changes a lot of history, and might cause the guy who originally traveled back in time to never be born. Or maybe the parents of the guy who invented time travel never met and time travel was never invented to begin with. In other words, just by traveling into the past and doing absolutely nothing to directly affect the future, you probably don't exist anymore and couldn't have traveled back in the first place. Do you see where I'm going with this? Time travel is pretty stupid and will never exist.
However, what if multiple timelines exist in parallel universes? Could time travel be possible then? Sure, but that's the only way it could work, otherwise just by traveling back in time, you miight change too much that the future you know no longer exists making it impossible to happen in the first place.
One last point I want to make about time travel that happened in a movie. In The Terminator, the machines send Arnold back in time to kill Sarah Conner, right? Well, we know they fail, they know they fail, so why don't they try again? Or better yet, why don't they send back a dozen Arnolds to kill her? This never made sense to me, but if you apply my theory of changing the past, it does make some sense. In their timeline, John Conner's dad is Kyle Reese who is from the future. So, that means that in order for John Conner to exist, a man had to travel back in time to bang his mom. This also means that no matter what the machines did, they would fail, John Conner would be born and lead the humans in a war against the machines. Do you think the machines knew this before they sent Arnold back? So technically, had they not sent him back, Kyle Reese would not have been sent back, John Conner would have never been born, and the machines would have won. Then again, they wouldn't have had to send Arnold back if John Conner didn't exist in the future to begin with. So, no matter what, this timeline already existed and there was nothing the machines could have done to win. I'm confused now.
In conclusion, time travel will never exist, or if it does, we will never know about it because we live in the wrong parallel timeline. Knowledge is Power!
