Stephen Hawking once suggested that the absence of tourists from the future constitutes an argument against the existence of time travel—a variant of the Fermi paradox. Of course this would not prove that time travel is physically impossible, since it might be that time travel is physically possible but that it is never in fact developed (or is cautiously never used); and even if it is developed, Hawking notes elsewhere that time travel might only be possible in a region of spacetime that is warped in the right way, and that if we cannot create such a region until the future, then time travelers would not be able to travel back before that date, so "This picture would explain why we haven't been over run by tourists from the future." Carl Sagan also once suggested the possibility that time travelers could be here, but are disguising their existence or are not recognized as time travelers.
i don't care
i believe it ~ it's time travelling ... period

That is true, there are no tourist from the future but there is also another theory out there.
Traveling back into the past is only possible when there is a machine. Now i know that doesn't make sense but here's an example.
January 1st 2020 3:00pm - Machine turned on. Now anyone from the future can come back to this date because there is now a "Portal" but you can't go back any further because there is no way to.
i say anything is possible.
i'm do not really understand why we can't travel back in time though... i'm sure there is a way that he hasn't thought of yet (if indeed time travel is possible)
great scott!
time flux capacitor and so on and so forth
just have to move faster than the speed of light. no big whoop

time is really a fascinating subject. like if the universe is supposedly 14 billion years old, how can we see past that? how can we see up to 47 billion light years away? for that light to reach us, we would have to be non existent by that model
