Add Yahoo as a preferred source to see more of our stories on Google. Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that ...

An artistic representation of antihyperhydrogen-4 — an antimatter hypernucleus made of an antiproton, two antineutrons, and an antilambda particle — created in a collision of two gold nuclei (left) ...

The best look yet at how a solar explosion becomes an antimatter factory gave unexpected insights into how the tremendous explosions work. The observation may upset theories about how the explosions, ...

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 ...

In 1932, physicists glimpsed antimatter for the first time — a strange mirror image of regular matter with mind-bending potential. Nearly a century later, this ghostly substance could someday fuel a ...

Physicists have created the heaviest clumps of antimatter particles ever seen. Known as antihyperhydrogen-4, this strange stuff could help us solve some of the most puzzling physics mysteries.

Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.
