Into the wormhole

I met Max Tegmark at a book event in Harvard Square last evening. Max is an MIT astrophysicist who believes our universe is only one of an infinite number of parallel universes, some of which are like this one in almost every detail. Max gave his reasons in a May 2003 article in Scientific American which is included in the 2004 edition of Best American Science and Nature Writing.

I asked Max whether there are red universes and blue universes. Absolutely, he agreed. In an infinite multifold of universes there must be one where John Kerry had a squeaky win in Ohio, or, if you are really disgruntled, there's another where Bush lost every state except Idaho.

In fact, if Tegmark's reading of the laws of physics is correct, you can pick the universe of your choice. The only trick is figuring out how to get there.

Maybe Canada is a more practical choice.
