What’s the latest matter with antimatter?

Hangst at the ALPHA experiment at CERN

Mind over antimatter: Jeffrey Hangst at the ALPHA experiment at CERN.

By Tushna Commissariat at CERN

While visiting CERN, the world’s biggest particle-physics laboratory, it’s easy to get swept up by the excitement of the Large Hadron Collider and its detectors, especially in the run up to it being switched back on in the coming weeks. But CERN is also host to a variety of other equally exciting experiments that probe some of the biggest unanswered questions in science, such as the experiments that probe the unwieldy world of antimatter. Indeed, CERN’s antimatter programme has received considerable attention in the past, especially thanks to the now-famous book (and later, film) Angels and Demons, where some antimatter was supposedly stolen from the laboratory and used to build a bomb! Suffice to say, antimatter is of interest to physicists and the public alike and so I caught up with physicist Jeffrey Hangst, who is spokesperson of the Antihydrogen Laser Physics Apparatus (ALPHA) experiment, which I also had the chance to visit.

Artist’s impression of a map of the Quantum Universe (Graphic courtesy of “ILC — form one visual communication”)

By Tushna Commissariat

Here’s a bit of Friday physics fun… I came across this rather interesting image that shows an artist’s impression of a map entitled “The Quantum Universe”. It includes six landmasses all floating in the Big Bang Ocean; including Dark Matter Landmass, Sypersymmetry Reef, Higgs Island and the Land of Ultimate Unification as well as others.

So go ahead and tell us which island you would like to settle down on. Be sure to look carefully at gems like Newton’s Lawn and Mount Einstein before you make your mind up!
