Does Antimatter Weigh More Than Matter?
January 26, 2012
Does antimatter weigh more than matter? University of California, Riverside, physicists want to know. Their finding could explain why the universe seems to have no antimatter and why it is expanding at an ever increasing rate. In the lab, the researchers took the first step towards measuring the free fall of positronium--a bound state between a positron and an electron. They separated the positron from the electron long enough to measure gravity's effect on them.
