(Phys.org) —A team of researchers at the University of California, Berkeley, is proposing a possible way to measure gravity's impact on antimatter atoms. In their paper published in Physical Review Letters, the team describes ...
(Phys.org) —The ASACUSA experiment at CERN has succeeded for the first time in producing a beam of antihydrogen atoms. In a paper published today in Nature Communications, the ASACUSA collaboration reports the unambiguous ...

The atoms that make up ordinary matter fall down, so do antimatter atoms fall up? Do they experience gravity the same way as ordinary atoms, or is there such a thing as antigravity?

(PhysOrg.com) -- Seventeen minutes may not seem like much, but to physicists working on the Antihydrogen Laser Physics Apparatus (ALPHA) project at the CERN physics complex near Geneva, 1000 seconds is nearly four orders ...
(PhysOrg.com) -- In 1932, scientists observed the first antimatter particle, a positron (or antielectron). Since then, scientists have observed heavier and heavier states of antimatter: antiprotons and antineutrons in 1955, ...
(PhysOrg.com) -- In the movie Angels and Demons, scientists have solved one of the most perplexing scientific problems: the capture and storage of antimatter. In real life, trapping atomic antimatter has never been accomplished, ...

It's a fundamental law of physics that even the most ardent science-phobe can define: matter falls down under gravity. But what about antimatter, which has the same mass but opposite electrical charge and spin? According ...
