The "B" theory of time really blows me away. I have a hard time wrapping my head around all points of time existing simultaneously. It's never a good bet to go against Einstein but is that really what is meant in relativity when it says all observers viewpoints are equally valid? Must all of time simultaneously exist like Brian Green's slices on a loaf of bread analogy to satisfy that tenant of relativity?
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
