Antimatter — the mysterious substance that's the mirror opposite of matter in most ways — falls downward in gravity like everything else in the universe, a team of physicists reported Wednesday in the ...

Antimatter has intrigued and confounded physicists for almost a century, and the effect of gravity on antimatter has been a point of disagreement. New research may have settled the debate by finding ...

A substance called antimatter is at the heart of one of the greatest mysteries of the universe. We know that every particle has an antimatter companion that is virtually identical to itself, but with ...

In context: Antimatter is a substance composed of antiparticles with an opposite electric charge compared to the corresponding particles in "ordinary" matter. Despite its opposite nature, antimatter ...

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. Physicists ...
