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 ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

In the world of science fiction, warp drives or antigravity devices are often powered by antimatter, which in real-life physics are mysterious particles that have an opposite charge and spin compared ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists are exploring the possibilities of antimatter propulsion as they try to achieve interstellar travel. While conventional ...

Our universe is filled with particles, such as electrons and protons, which make up all the stuff on our planet and beyond: animals, plants, people, planets, asteroids, stars, gas clouds, and galaxies ...

A test performed on antihydrogen atoms has shown that gravity acts on matter and antimatter in a similar way. The experimental feat is the latest in efforts to probe the crossover between theories of ...

Discerning whether a nuclear reactor is being used to also create material for nuclear weapons is difficult, but capturing and analyzing antimatter particles has shown promise for monitoring what ...

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 ...
