(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 ...
The standard model of particle physics suggests that matter and antimatter are equal and opposite in every way. Yet the observable Universe is made almost entirely of matter—an asymmetry that remains one of the greatest ...

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) -- Researchers at RIKEN, Japan's flagship research institution, have successfully devised the world’s first experimental technique for measuring ground-state hyperfine transitions of antihydrogen. By enabling ...
