| I see what you mean now if you only believe in those two time travel theories, and modern physics suggests that the parallel timeline 'Sliders' theory is the correct one. Your explanations are excellent.
But in fiction, usually bad fiction I confess, there has also been a third idea; that you still have a single timeline, but it is not immutable or unchangeable. In that kind of time travel you could change the past, and have photos fade out in the future.
And I think what Profit4Motive was saying, correct me if I'm wrong, is that that theory was used in BTTF. |
