    We are all travelling to the future. One moment at a time.

    Traveling into the future, we are all doing that. I have a sneaking suspicion that due to the expansion of the Universe, the expansion prevents us going backwards in time. It's like trying to swim against the tide.

    it's not that you CANT travel backwards in time, it's just that if you did, you never would have done anything different - AND there would have to be a physical 'path' you traveled which 'flowed' negatively through time, - a path which must have existed on both sides of the time dilation you observe and travel upon - meaning that any temporal wormhole (or whatever means of connecting two points across time) connecting 1970 earth to 2970 earth MUST to be there in 1970 even if YOU never went to 2970 FIRST to create the wormhole, because 1970 happened first, and you're in 2970 creating the wormhole.
    You're trying to go back and change things - whatever happens cannot be undone, period. If ever time travel to the past gets invented, they must not have changed anything or if they did we can't tell.

    1 hour later is NOT the future but the past. 1 hour now is the future NOT the past.

    How would one know if the person were from the future?

      He could tell you your past . . . before it happened.

      @MCOult if he's from another planet how does he know your past?

    What your science theory says us that maybe people could travel to the future but could never return to their own time.

    Just a person who likes science, not scientist. If you look up university of toronto, they have discovered photons travelling to the past. Pretty wild.

      Because they have zero mass.

    That’s a bunch of nonsense Fermi’s paradox, has already proven that time travel doesn’t exist.

    Lol - if I send you on a spaceship nearing the seed of light!! There is no such thing and never will be it's all theory and sc-fi!
