Breakthrough: Gravity’s Effect on Antimatter

The Antihydrogen Laser Physics Apparatus (ALPHA) collaboration is an international group working with antihydrogen atoms at the European Organization for Nuclear Research (CERN), to understand the fundamental symmetries between matter and antimatter. We are joined by professors Joel Fajans and Jonathan Wurtele, NSF-supported researchers at the University of California, Berkeley, to announce the breakthrough results of an experiment looking to understand gravity's effect on antimatter.
