→Artificial antimatter: what is a "magnetic charge" do you mean "electric charge"
== Artificial antimatter ==
== Artificial antimatter ==
Antimatter is made in supercolliders such as [[CERN]], by smashing beams of highly charged particles together. This results in pair production, the creation of a particle and its antiparticle. One of the aims of modern physics is the creation of larger and more complex forms of antimatter. In 1995 CERN announced that it had produced 9 hydrogen atoms. In 2003 Antihelium was created. Physicists are now working on the creation of 'cooler' antiatoms, as the ones produced so far are more energetic than atoms on the surface of the sun, and this makes the extremely hard to study. Another issue being studied is that of containment: since antimatter explodes on contact with normal matter, it is difficult to hold it for study. Smaller particles are held in place by carefully managed magnetic fields, but the larger antiatoms, having no overall magnetic charge, are much harder to contain.
