MEASUREMENT OF THE GRAVITATIONAL MASS OF ANTIHYDROGEN

MEASUREMENT OF THE GRAVITATIONAL MASS OF ANTIHYDROGEN
To oversimplify it, antimatter is the opposite of matter. The two are mirror images with opposite electric charges. But, do the two respond in opposite ways to gravity? Instead of falling down, would antimatter “fall up”? If antimatter does go up instead of down, it will cause scientists to reevaluate how the universe works.
These questions have existed for over 50 years, but now ALPHA collaborators at CERN have been able to approach the problem; an incredible feat in itself. There have been no definitive conclusions yet, but when the experiment resumes in 2014 with a new antimatter trap, researchers hope to achieve more significant results.
