I am told that I was perverse to recommend Einstein on the Beach. I confess I don't own it myself. How many CDs is an 8 hour opera?
I am currently reading a biography of Einstein. I always read books about physics, books about black holes and string theory, stuff like that. I didn't realize he was trying to explain why gravity and acceleration feel the same.
What I want to know is: if I have 10 suns arranged in a row and each is moving away from the ones next to it at 1/10th of the speed of light, why aren't the two end ones separating at the speed of light? And if I have 11, what then?
