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 ...

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 ...

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.

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 ...

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.

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 ...

Created — and sewn individually — by Julie Peasley, the zoo currently comprises 33 toys of particles and antiparticles. Supersymmetric partner particles are to follow soon.

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 ...
