This talk is really interesting. The earth is somewhat like a time machine. The diagram he shows is a really good representation of this. When we look at the nearest set of stars we are seeing what was there about about 10 years ago. If we looked to the center of the galaxy it is 1000s of year ago. Andromedia the nearest big galaxy and is 200 million year ago. And that is before we believe human even existed!
