There's never been anyone from the future to now or the past, so there never will be
I highly doubt that they would travel back and say "Hey dudes, in the future you can totally time travel"
acording to Einstein's famous E=mc^2 equation. it says basically that it is impossible to travel at the speed of light or faster than the speed of light since you would need a mass thats equal or less to zero for that. time does seem to dilate when traveling closer to speed of light therefore time travel would be possible only if surpassing speed of light, which is impossible due to the mentioned above, mass problem.

Except scientists recently made something go faster than the speed of light meaning Einsteins theory was wrong.http://www.bbc.co.uk/news/science-environment-15791236
the article does say there could be wrong data and still need further proof. and it was done with a neutrino which is a subatomic particle of basically 0 mass which means it travels at speeds similar to speed of light
i wanna go to the future to see if i i do have an awesome job. IF NOT have a awesome job.
Well of course you'd be alive. Think of it this way, when you arrive in the future, your future self would be exactly the same as your current self because your future self is your current self. The only way you can meet another you is if you travel to the past or to another dimension.
The theory of general relativity predicts that if traversable wormholes exist, they could allow time travel.[2] This would be accomplished by accelerating one end of the wormhole to a high velocity relative to the other, and then sometime later bringing it back; relativistic time dilation would result in the accelerated wormhole mouth aging less than the stationary one as seen by an external observer, similar to what is seen in the twin paradox. However, time connects differently through the wormhole than outside it, so that synchronized clocks at each mouth will remain synchronized to someone traveling through the wormhole itself, no matter how the mouths move around.[20] This means that anything which entered the accelerated wormhole mouth would exit the stationary one at a point in time prior to its entry.For example, consider two clocks at both mouths both showing the date as 2000. After being taken on a trip at relativistic velocities, the accelerated mouth is brought back to the same region as the stationary mouth with the accelerated mouth's clock reading 2005 while the stationary mouth's clock read 2010. A traveler who entered the accelerated mouth at this moment would exit the stationary mouth when its clock also read 2005, in the same region but now five years in the past. Such a configuration of wormholes would allow for a particle's world line to form a closed loop in spacetime, known as a closed timelike curve.It is thought that it may not be possible to convert a wormhole into a time machine in this manner; the predictions are made in the context of general relativity, but general relativity does not include quantum effects. Some analyses[who?] using the semiclassical approach to incorporating quantum effects into general relativity indicate that a feedback loop of virtual particles would circulate through the wormhole with ever-increasing intensity, destroying it before any information could be passed through it, in keeping with the chronology protection conjecture. This has been called into question by the suggestion that radiation would disperse after traveling through the wormhole, therefore preventing infinite accumulation. The debate on this matter is described by Kip S. Thorne in the book Black Holes and Time Warps, and a more technical discussion can be found in The quantum physics of chronology protection by Matt Visser.[21] There is also the Roman ring, which is a configuration of more than one wormhole. This ring seems to allow a closed time loop with stable wormholes when analyzed using semiclassical gravity, although without a full theory of quantum gravity it is uncertain whether the semiclassical approach is reliable in this case.
Wait, wouldnt that only make sense if you didnt return? If you go into the future to see yourself and then somehow return to your own time, then you would have returned to fufill your role as your later future self.Or am I misunderstanding the arguement?
I think the closest we would come to having some sort of "Time Travel" would be to temporarily put a person in a stasis or suspended animation and reawakening him/her 100 or so years in the future.Granted, this isn't TRUE time travel seeing as how it's only one way, but it is an option.
