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!
