Did anyone else listen to Opie and Anthony this morning, when they were talking to theoretical physicist Michio Kaku? He wrote books such as "Hyperspace," "Parellel Worlds," and his latest book is "Physics of the Impossible."

On the show, he talked about the idea that we really live in a Multiverse, where parallel realities, or universes, are created as a result of the choices we make or significant events playing out differently. Like, there is a universe where I didn't get fired from Starbucks, and as a result didn't work at Borders, and probably didn't become a journalist, and so on.

And DC and Marvel have been dealing with Multiverse storylines for how long now? Has this idea of an actual Multiverse been around for awhile, and I'm just hearing about it now? Or were comic book writers on to something before the scientists thought it was possible?
