Velcroman1 writes: Scientists at the Large Hadron Collider have created antimatter in the form of antihydrogen, demonstrating how it's possible to capture and release it. The development could help researchers devise laboratory experiments to learn more about this strange substance, which mostly disappeared from the universe shortly after the Big Bang 14 billion years ago.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. "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."
