Q:Is it even _theoretically_ possible for time travel to exist, without resorting to overly artificial and theatrical rules governing it? If yes, how does one resolve things such as the Grandfather Paradox?

Need a refresher on the Grandfather Paradox? Watch this:

The thing about a paradox is that it’s not easily resolvable. That’s why it’s a paradox. In my opinion, you have to do some pretty theatrical backflips in logic to make sense of something like this. Saying that if you go back in time and kill your grandfather, there must be a parallel universe where that didn’t happen is pretty artificial. It’s not impossible, just artificial.

Really wanna bend your mind in half? If matter can not be created or destroyed, then aren’t there more atoms in that universe if you travel back in time and meet yourself, defying the laws of physics? Hmm?

Of course, traveling forward is still fine, in theory. Bring me backa sports almanac.

  1. just-another-stop said: smart! never thought of the atoms bit… something I learnt in thermodynamics.. Time travel also has something to do with entropy. theoretically that is. it IS possible to travel back in time, but this process is not entropically favoured. Thoughts?
  2. deadoldbones said: Nothing in the known laws of physics prohibits time travel to the past. Time Travel in Einsteins Universe by J. Richard Gott is a very accessible book that runs through many of the possibilities.
  3. oceanbluedreams said: I’ve always wondered about the “matter cannot be created or destroyed” time paradox! How would that even work, is there a theory on that?
  4. thatboypossessed said: What if in the future we’ve come up with a solution and that solution was to turn us into transparent entities that can’t physically touch anything and that today is what we believe to be ghosts?
  5. iamvishnu said: “Most people see time as a strict progression of cause to effect, when in actuality, it’s more of a wibbly-wobbly, timey-wimey… thing.”
  6. sheikhmaat said: Stephen Hawkins also explained it in terms of “background radiation” where it’s not possible to create/use a time machine to travel back in time anyway. Whereas if you approach the correct speeds, going into the future without aging is plausible.
