Well, yeah, but the unified field theory is very related to anti-gravity. It's like the electromagnetism: a magnet moving near a wire can produce electricity and electricity can produce magnetic fields... After we include the gravity in the theory it's a small step to understand how it works and how to "undo" it!
Maybe the answer doesn't lay on gravity itself but on another of the four fundamental forces... Who knows! The possibilities are infinite... And I'm starting to sound like Carl Sagan!
Using the LHC would be sooo cool! It's like my childhood dream!![]()
