Scientists trap ‘antimatter’ hydrogen atoms | Raw Story Until now, experiments have produced anti-atoms, namely of hydrogen, but only in a free state. That means they instantly collide with ordinary matter and get annihilated, making it impossible to measure them or study their structure. In a paper published on Wednesday by the British journal Nature, a team at the European Organization for Nuclear Research (CERN) in Geneva explain a method of snaring these so-called antihydrogen atoms. This could be very good news, ifyou believe that anti-matter will one day power the Earth....BAD news if somehow this becomes a weapon. Lets see ...... Power source? ... Weapon?
