Big Bang stuff is cool. I like Perceptual Psychology, because it takes the things your must use to seeing and states "That's not really what that is." Big bang stuff is something that people can't take for granted like seeing colors because it extends past what we know and see everyday as "normal" since no one has seen a big bang. But we all see colors that aren't mathematically possible for us to see.

The next random person to check this thread is going to get quite the crash coarse. Good stuff guys.
