No direct measurements exist, however, that prove they do. UC Berkeley scientists, part of the ALPHA collaboration at CERN, are working on just such an experiment and have some very rough results.]]> http://newscenter.berkeley.edu/2013/04/30/is-antimatter-anti-gravity/feed/ 0 http://newscenter.berkeley.edu/2012/03/08/new-discovery-key-to-understanding-neutrino-transformation/ http://newscenter.berkeley.edu/2012/03/08/new-discovery-key-to-understanding-neutrino-transformation/#comments Thu, 08 Mar 2012 16:16:05 +0000 Robert Sanders http://newscenter.berkeley.edu/?p=26025 The joint China-U.S. Daya Bay experiment to explore the multiple personalities of neutrinos announced its first results today (Thursday, Mar. 8), paving the way for further experiments to determine whether neutrinos and antineurtinos have similar split identities. If not, it may provide a clue to why the universe has more matter than antimatter, and thus why we exist.]]> http://newscenter.berkeley.edu/2012/03/08/new-discovery-key-to-understanding-neutrino-transformation/feed/ 0 http://newscenter.berkeley.edu/2011/06/05/cern-group-traps-antihydrogen-for-more-than-16-minutes/ http://newscenter.berkeley.edu/2011/06/05/cern-group-traps-antihydrogen-for-more-than-16-minutes/#comments Sun, 05 Jun 2011 17:00:54 +0000 Robert Sanders http://newscenter.berkeley.edu/?p=12369 The ALPHA experiment at CERN in Geneva has successfully trapped rare antihydrogen atoms for 1,000 seconds, or more than 16 minutes. This is long enough to start experimenting for the first time on antimatter atoms to determine whether they act like normal matter.]]> http://newscenter.berkeley.edu/2011/06/05/cern-group-traps-antihydrogen-for-more-than-16-minutes/feed/ 0 http://newscenter.berkeley.edu/2010/11/17/antihydrogen/ http://newscenter.berkeley.edu/2010/11/17/antihydrogen/#comments Wed, 17 Nov 2010 18:28:33 +0000 Robert Sanders http://dev-newscenter.berkeley.edu/?p=1129 The particle accelerators at CERN in Geneva produce scads of antiprotons, which five years ago were combined at high speed with positrons to create for the first time antimatter atoms: antihydrogen. Those atoms annihilated with normal matter within microseconds, but an international team involving UC Berkeley and LBNL physicists has succeeded in slowing such atoms down and trapping them for a tenth of a second.]]> http://newscenter.berkeley.edu/2010/11/17/antihydrogen/feed/ 0
