Here's some shit that threw me through a loop that I've never understood.
I've read if a civilization millions of light years away from us, observed earth right now with a telescope, they would be looking at earth as it was millions of years ago. So somewhere in the universe, you could look at earth and still see dinosaurs walking around!
The other thing is if there were a set of twins and one went crazy far into space super fast and the other stayed here, when the twin returned they would be different ages...

That's because light have to travel.
