Since I'm definately not a scientific person this may be a stupid question but......

Wouldn't time travel not only involve going back into time but also going back to a certain position in the universe. Like say 500 years ago, the earth and sun were not at this location but somewhere else in the rotation of the Milky Way, and the Milky Way was somewhere else in the universe.

So for time travel to really work, you would have to go back in time and go to the actual spot and rotation of the earth at that particular time. Am I off base?

It's a problem only if you believe in that new-fangled Copernican stuff.

I'm not a scientist either, but it has always been my understanding that that is true, ie time travel would also have to be distance travel if you want to end up on the Earth and have an atmosphere to breath. (You also better make sure you don't land 100's of ft. up or under the ocean.)
