LHC Scientists Create and Capture Antimatter

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.'"

    If they really created antihydrogen, they should prove it by taking a photo.

    We'll have to be extra cautious that they don't just take a photo of regular hydrogen and apply a negative filter to the image.

    It would be a big thing if someone created anti-copper AND it didn't behave exactly like copper when supplied with an anti-potential from an anti-battery.

    Would anti-physicists finally get the polarity correct on the anti-battery or would it still be backwards?

    PETAM (People for the Ethical Treatment of Antimatter) are not going to be pleased with this. Especially the bits about physicists staging pit-bull style "dog fights" between matter and antimatter, and placing quantum mechanics based bets to the outcome of the duels.
