...Gabrielse team, which goes by the name of Antihydrogen Trapment Collaboration (ATRAP), was able to create an atom of anti-hydrogen, the anti-matter counterpart of hydrogen, by joining an antiproton, the counterpart of a proton, and a positron, the counterpart of an electron. Except for their charges, both the anti-proton and the positron are identical in nearly all respects to their antimatter counterparts...
...most difficult part of creating anti-hydrogen involves overcoming repulsive forces to bring together the oppositely-charged antiproton and positron...
...machine the size of a football field uses magnets to guide anti-protons into and positions together. When the two get close enough, anti-hydrogen forms...
...also said that ATRAP and ATHENA experiments differed in several notable ways, including in methods of detecting the anti-hydrogen after creation and in the quantity of positrons used...
...that the anti-hydrogen has been created, the Harvard team still must travel to Geneva to create more of it to study. They now hope to determine whether antihydrogen and hydrogen—and analogously, antimatter and matter—are exact mirror images of each other, or if other differences exist between...
