Infinity Will Hurt Your Head

Another great documentary from BBC Horizon. I like the idea that in an infinite universe there are an infinite number of exact copies of you - with your memories and personality - out there reading this blog post right now. And if Neil Turok's cyclical model is correct then our own local observable universe has gone through the big bang, heat death and brane collapse/singularity/big bang an infinite number of times, which means, of course, that someone with your name and your memories lived your life and died an infinite number of times an infinity ago.
