Currently, one of the major goals in ultracold science is to cool antihydrogen atoms to as close to absolute zero as possible. Ultracold antihydrogen would pave the way toward ultraprecise antimatter experiments that could ...
Trapping antihydrogen atoms at the European Organization for Nuclear Research (CERN) has become so routine that physicists are confident that they can soon begin experiments on this rare antimatter equivalent of the hydrogen ...

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.

(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?
