Re: Time travel
Bowser, if time travel were possible, there's a factor that would have to be considered:
The universe is far from static; the Earth rotates, orbits the sun which orbits the galaxy (in the Orion arm). Our galaxy is attracted towards the great attractor, all this while the universe is expanding !
It's going to be a hell of a calculation to figure out where precisely we were at the moment our time machine was programmed to land. Otherwise, we'd land in space, somewhere, or inside the mantle of the Earth!
