Hey Professor Idiot!! Why dont you test the theory of relativity, climb a 3,000 ft cliff, when you reach 3,000 ft, take a deep breath and lean back and let go, i bet MY THEORY IS RIGHT, WHAT COMES UP MUST COME DOWN. I made that up, i created the theory of relativity. Oh and created the first bow, and gun, and shot the worlds biggest deer, moose, black bear, cougar, wolf, kangaroo, zebra, giraffe, lion, ohh the list goes on and on.
