I've currently been reading Anathem by Neal Stephenson and it has raised a lot of questions in my mind about the divergence of time-lines and reality. I'm not a scientist or philosopher in name, but these kinds of topics in the scientific and philosophical sense really really intrigue me as I'm certain that other Nerdfighters have the same tendency.
The Schrödinger's cat thought experiment states that the cat at one point is simultaneously alive and dead and this is due to quantum mechanics. One supposition of Neal's in Anathem is that at the point where the cat is both dead and alive diverges into two separate time-lines. Now, if that were to be true there would be an almost infinite number of universes diverging constantly. Would this be a possibility? It is hard to imagine it could be, but if you are aware of Buddhist beliefs, you might know similar thoughts.
I know I am trying to tackle ideas that are much bigger and incomprehensible to many, but it would be nice to have a discussion about such things here. Please, if you have ever been interested in or questioned reality and the possibility of multiple universes post your thoughts here. I know there will be a lot of divergence of opinion and 'knowledge', so let's try to keep this to a minimum of mud slinging.
