orbital mechanics is supposed to be simple calculus. Get planets moving from one solar system to another, well a civilization that built the pyramids could handle it, and its possible DARPA is playing with it too.
can you do simple calculus?
and wtf, humans built the pyramids, but there is no way we are going to move a planet.
did you do some really bad drugs at some point in your life and obliterate whole chunks of brain cells?
