[Atrocities]

What, if anything, would be considered an opposite of a black hole? If gravity is so powerful that it can even bend light, then how could it be countered? Anti-Gravity? Just curious about this, if something like anti-gravity could be created, and when it comes into contact with gravity, say that of a black hole, what kind of energy do you think it would produce? Could it produce anti-matter? Could any energy, if any is created at all, be harvested and used for our benefit?

And what about artificial gravity? We know we can simulate gravity with centrifugal force, but that really isn't a practical means by any definition for the kind of gravity we would need to have if we are ever to honestly try and explore the stars.
