doobie, I looked up bubble universe on wikipedia and that sounds very possible. They said Andrei Linde, the guy that proposed it, said we were part of a child universe from the actual universe. man that would make a great thread in itself.
skunk, my wife liked the skunk rule of physics also. I agree that the opposite of time advanced travel seems impossible. I chose these words cuz you brought up a good point. We all agree that we can go forward, but which way is backwards. if you are going backwards, you are still going foward in your mind's referrence of time.
