3 theories of time travel

I found this excellent infographic over at techeblog.com which explains 3 theories of time travel; fixed timeline, dynamic timeline and multiverse.

As I commented on the original site, I have a problem with multiverses! They’re too much of an easy ‘get-out-of-jail-free’ card and I can’t find any sound scientific basis for the creation of all the additional energy and mass required to go round creating new universes willy nilly…let alone specify a defined moment for divergence.

So many problems, so little time…I think I have an idea for another blog post!

  1. Oh, cool. Actually, there’s a 4th theory that’s a bit of a hybrid. I can’t tell you about it, though, because a future version of my great grandson told me that telling you would destroy the space-time continuum.

  2. Hi Justin,
    I’m very happy the (great) grandfather paradox didn’t get a hold!
    Naturally I’d be very interested in the 4th theory…but not at the expense of the space-time continuum…there are rumours it’s quite important!
