Comment on If I snapped you back in time 650 years right this very second, how would you use your current knowledge to succeed?

  This. Once you understand enough about the universe how all coordinates are relative and everything is moving relative to everything else… Like, how the fuck is time travel supposed to work it it was anywhere like this naive movie idea of it? Time travel Hollywood style is literally not a continuous operation and as such absolutely unphysical.

    Well since all cordninates are realative, and your relative position to earth is unchanging, wouldn’t that mean that everything else moves around you while you and the earth stand still and go back in time?

      If the earth is going back in time as well then the whole planet as it is today would begin to freeze as a rogue planet unconnected to any star.

      There’s a reason the tardis is a time and space ship.

        Sorry I guess I should have clarified, but I think the other reply said it alright.

        basically, if I move backwards in time, in my own spacetime, then my relative position in the universe would remain unchanged. hence Maybe I go back to where I was in time and relative to the universe(my parent’s home 20 years back). the tardis can put you back in time and change where in that time you were.

        This is all theoretical, but maybe hollywood isn’t as far off as we think (even if they would have arrived there by chance and not logic)

      Good one. I am the frame of reference myself… And we rewind time around me, kind of.

      Okay, that at least does not sound so wrong like the “teleportation-style” approach!

      What you say is like the extreme form of how time travel worked in Primer (the movie), which in fact is an interesting variation.
