Does Antimatter Fall Up Or Down? New Device May Provide Answer



When a particle meets its antiparticle, they annihilate each other, giving off a burst of energy — a proof of Einstein's famous equation, E=mc2, which revealed mass can be converted to energy and vice versa. A gram of antimatter annihilating a gram of matter would release about twice the energy as the nuclear bomb dropped on Hiroshima. (Have no fear of antimatter bombs popping up anytime soon — researchers are very far from creating anywhere near a gram of antimatter.)
