The Home of All Things Interesting

Anti-Matter

Trapped at CERN

First Time in History

 

 

Physicists working at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, have succeeded in trapping antihydrogen — the antimatter equivalent of the hydrogen atom — a milestone that could soon lead to experiments on a form of matter that disappeared mysteriously shortly after the birth of the universe 14 billion years ago.

 

The first artificially produced low energy antihydrogen atoms — consisting of a positron, or antimatter electron, orbiting an antiproton nucleus — were created at CERN in 2002, but until now the atoms have struck normal matter and annihilated in a flash of gamma-rays within microseconds of creation.

The ALPHA (Antihydrogen Laser PHysics Apparatus) experiment, an international collaboration that includes physicists from the University of California, Berkeley, and Lawrence Berkeley National Laboratory (LBNL), has now trapped 38 antihydrogen atoms, each for more than one-tenth of a second.

Now we are getting our moneys worth out of the LHC, lets hope it does not destroy the earth.
