...Either end well or, you know, destroy the Earth
http://www.foxnews.com/scitech/2010/11/17/breakthrough-mysterious-antimatter-creat...Scientists working on the big bang machine in Geneva have done the seemingly impossible: create, capture and release antimatter. Trapping any form of antimatter is difficult, because as soon as it meets normal matter -- the stuff Earth and everything on it is made out of -- the two annihilate each other in powerful explosions.
In a new study, physicists were able to create 38 antihydrogen atoms and preserve each for more than one-tenth of a second. The antihydrogen atoms are composed of a positron (an antimatter electron) orbiting an antiproton nucleus.
"We are getting close to the point at which we can do some classes of experiments on the properties of antihydrogen," said Joel Fajans, a University of California, Berkeley professor of physics, and LBNL faculty scientist. "Since no one has been able to make these types of measurements on antimatter atoms at all, it's a good start."
