Ok, here's another one I'd love to hear some opinions on.

Where is Earth?

In regards to Beast Wars, it's stated that Earth's location is a carefully guarded secret in the years post The Great War and the signing of the Pax Cybertronia.

But how is that possible?

Transformers, on both sides, have been trapsing back and forth from Earth to Cybertron for years, how is it that it's location is suddenly a secret?

Was it moved?

Was it blown up and the population moved to another planet?

Its reason for being a secret is obvious: with the development of TransWarp technology, someone might want to go back in time and change thing (like that would happen), but how could they control that information?

I'd love to hear some theories.
