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.

Eight years ago, the International Space Station detected weird antimatter particles that challenge our entire understanding of physics. Now, researchers have proposed that mysterious cosmic ...

A black hole made from pure light is impossible, thanks to quantum physics A “kugelblitz” would be foiled by particles and antiparticles that carry energy away ...

Another discovery found that the degree to which these particles and antiparticles are changed by solar effects depends on the shape of the wavelength those particles travel in.

They observe for the first time the decay of baryons, particles that make up the majority of the matter in the observable universe. After the Big Bang, matter and antimatter were created in equal ...

The discovery of the new antihypernucleus could help scientists better understand the state of the universe just a millionth of a second after the Big Bang.

Particles and antiparticles have opposite charges, and they annihilate if they interact, turning into pure energy.

It’s a fundamental principle of physics that particles with opposite charges attract each other, while those with the same charge repel. But now, scientists at the University of Oxford have ...

Forward-looking: Antimatter consists of particles with properties opposite to those of regular particles. It plays a central role in modern physics research and forms naturally through cosmic ...

For the most part, particles and their oppositely charged antiparticles are like perfect mirror images of one another. But some particles disobey this symmetry, a phenomenon known as charge-parity ...

A complete survey of all the particle and antiparticle activity that goes on during the Sun’s 11-year cycle has found previously unknown ways these particles behave. Cosmic rays coming from ...
