I've just seen 'The Butterfly Effect' movie last night and seemed a plausible way of dealing with time travel, however only to a limited extent. What do you think?
I loved that movie, but I don't know if it would work. The general idea is that you have "blackouts" where you don't know what happened. Then you go back in time and change what happened during the blackouts. Then you go back to the future and everything has change.
It actually reminds me of something that apparently happens in quantum mechanics. It's an experiment related to the double-slit experiment, called the "delayed choice quantum eraser". I can't remember how it works, but it somehow involves the future determining the past, in some self-consistent way.
The movie is about human beings though, which makes it hard to test it for consistency.
In physics, time travel is called a "closed time-like curve". The paradoxes either involve something happening to prevent you from going back in time at all, or information being created from nowhere.
Has anyone seen a time travel movie/story where they travel back in time, but instead travelling back to the future, they just stay and wait? That might not involve so many contradictions.
