![]() ![]() ![]() But there's one problem with that theory: during the Big Bang, matter and antimatter should have been created in equal quantities and destroyed each other completely, which leads physicists to believe that there must have been some small difference between the two that gave matter an edge. According to the current understanding of physics, the Standard Model, the two should be diametrically opposed in every way. For example, the 'electrons' of antimatter have a positive charge, while ordinary electrons have a negative charge. While hydrogen, the first element on the periodic table, has been studied for two and a half centuries, it has only been in the last few years that antihydrogen can be held in a stable enough state for direct study without being annihilated by contact with a particle of ordinary matter.Īs its name would imply, antimatter is, in many ways, the opposite of matter. ![]() Physicists at CERN's Antihydrogen Laser Physics Apparatus (ALPHA) in Switzerland beamed a laser onto particles of antihydrogen, the antimatter counterpart to normal hydrogen, to determine whether light behaved in the same way for both materials. For the first time, scientists have been able to shine a light on one of physics's most mysterious substances – literally. ![]()
