Nemesis: The Search for Antimatter in the Universe > > Presented by Professor Joss Bland-Hawthorn, Federation Fellow at the > University of Sydney > Wednesday 6 October 2010 > 5:45pm – 6:45pm > > It’s the ultimate battle of the universe: when normal matter and antimatter > come together, they’re annihilated, and all the mass is converted into energy. > Fortunately, the Universe today is composed almost entirely of matter, with > very little antimatter. However, the laws of physics require that the Universe > began with equal amounts of both. The origin of the asymmetry is not known, > but a possible explanation relies on some bizarre events in the early > Universe. Recently, however, the annihilation signature of antimatter has been > observed emanating from the centre of the Galaxy, at a rate that corresponds > to the annihilation of 16 billion tonnes of antimatter every second. > > Find out what these observations are telling us about the creation of > antimatter in violent processes at the centre of our Galaxy. Learn how > research by the Astrophotonics group at Sydney is shedding new light on the > origin and nature of these antimatter signals. > Date and Time > > Wednesday 6 October 2010 > 5:45pm – 6:45pm > Eastern Avenue Auditorium Register at: http://www.science.usyd.edu.au/outreach/forum/lecture3.shtml
