Scientists Make Breakthrough in Antimatter Research

CERN researchers make a major step in understanding antimatter by trapping antihydrogen atoms and controlling them with lasers.

Antimatter is a concept that oozes sci-fi, evocative of amazing engines, time travel and most likely destruction of the whole universe. Or maybe it’s a parallel-worlds-are-everywhere-around-us type of thing. In any case, this idea comes to us from the law of physics that predicts that there should be an antimatter particle for every particle of regular matter. But if the two shall ever meet, there’d be a release of energy, annihilating both.
