Oh! I just figured out red shift. I always wondered how they knew what colour it was supposed to be, to determine how far red it had shifted and thus how fast it was moving. But I'm stupid, because there'd be the marker wavelengths for various elements to go by. Wacky stars.

In other science news, it's almost four in the morning. I actually turned my computer on for this, too.
