A new physics discovery explores why there is more matter than antimatter in the universe. The latest research findings, which involved significant contributions from physicists at the University of Melbourne, have been recently ...


Advancing the study of antimatter

Mar 26, 2008 | User rating: 4.4 / 5 after 79 vote(s) | pda version

“Right now, most physicists would predict that hydrogen and antihydrogen have the same properties,” Gerald Gabrielse tells Physorg.com, “What’s irresistible is that we of the opportunity to – potentially – look for ...


Study confirms 1966 prediction: The most energetic particles in the universe are not from the neighborhood

Mar 21, 2008 | User rating: 4.8 / 5 after 43 vote(s) | pda version

Final results from the University of Utah’s High-Resolution Fly’s Eye cosmic ray observatory show that the most energetic particles in the universe rarely reach Earth at full strength because they come from great distances, ...
