Inside the antimatter factory: ALPHA-g measures effects of gravity on antihydrogen

New research has shown that if you drop a piece of antimatter, it will fall down to the ground just like regular matter. This rules out suggestions that antimatter could fall up, along with the existence of repulsive matter and antigravity machines. Earlier this year, we toured the antimatter “factory” at the CERN particle physics laboratory near Geneva, Switzerland, and saw the ALPHA-g experiment that was set up to test gravity’s effect on antihydrogen. Team member Jeffrey Hangst told us what’s next for antimatter research. – Subscribe ➤ Get more from New Scientist: Official website: Facebook: Twitter: Instagram: LinkedIn: About New Scientist: New Scientist was founded in 1956 for “all those interested in scientific discovery and its social consequences”.
