A lot of that stuff is explained in Stephen Hawking's "A Brief History of Time" and "The Universe in a Nutshell", also in Stephen King's "Timeline" and Madeline L'Engle's "A Wrinkle in Time"

Astrophysics, dimensional analysis, p-branes, multiple realities, Chaos Theory, the Butterfly Effect (not the movie), and the possibility of time travel are all hobbies of mine, nearly all of which are mentioned in those books and that flash movie.

It's been believed that there are dimensional "strings", some so microscopic that we can't even see them, and some wrapped up in each other..

I really want to check this book out, it explains the theory of multiple dimensions very clearly.
