Antimatter embraces Earth, falling downward like normal matter

Antimatter falling through a tube-like structure

Antihydrogen atoms (blue) fall inside a magnetic trap and annihilate in an experiment to measure the effects of gravity on antimatter.

For those still holding out hope that antimatter levitates rather than falls in a gravitational field, like normal matter, the results of a new experiment are a dose of cold reality.

Joel Fajans

Professor

Ph.D. Massachusetts Institute of Technology, 1985. Joined Berkeley faculty in 1988. Awards: Hertz Foundation Fellowship, American Physical Society Simon Ramo Thesis Prize, Hertz Foundation Thesis Prize, NSF Presidential Young Investigator Award, ONR Young Investigator Award, Sloan Fellowship, Fellow of the American Physical Society.

Research Interests

Although most of the universe is in the plasma state, the basic properties of plasmas are not well understood. Plasmas are collective systems, and exhibit remarkably complicated nonlinear behaviors like turbulence and chaos. Better...
