Antimatter was initially discovered in 1932 when physicist Carl David Anderson observed positrons—the antimatter form of an electron—in cosmic rays by passing them through a cloud chamber.

Scientists are exploring the possibilities of antimatter propulsion as they try to achieve interstellar travel. While conventional rockets provide high thrust, they struggle with low efficiency.

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 ...

Antimatter can produce more energy than anything else we know of, but it’s very fickle. A new field analysis explains what we need in order to progress with antimatter propulsion. While an ...
