Does antimatter fall up? Experiment could provide the answer
• http://arstechnica.com, by Matthew FrancisResearchers from the ALPHA experiment at CERN realized their antihydrogen trap could help answer that question. By releasing antihydrogen atoms—consisting of an antiproton and a positron—they could measure whether the atoms fell up or down. Using data they had already obtained, the ALPHA team determined they didn't yet have enough data to rule out antigravity or strange behavior in antimatter.
