If you believe Bob Lazar's claims that the aliens use gravity manipulation to travel the distances between stars and galaxies, then wouldn't that mean you could travel to a galaxy 70 million light years away and look at dinosaurs through a telescope?

If you used something like a wormhole or the gravity machines Bob Lazar described to quickly travel those distances, then in theory, you could go to a galaxy 70 million light years away and look through an advanced telescope and you could see dinosaurs walking around on Earth? You'd be watching the past. Wouldn't that be a wild ride. You could actually observe our past, record it on a recorder and then come back and show everybody dinosaurs from 70 million years ago.
