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.

In experiments at the Brookhaven National Lab in the U.S., an international team of physicists has detected the heaviest “anti-nuclei” ever seen. The tiny, short-lived objects are composed of exotic ...

The newly found antiparticle, called antihyperhydrogen-4, could have a potential imbalance with its matter counterpart that may help scientists understand how our universe came to be. When you ...

Scientists studying the tracks of particles streaming from six billion collisions of atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) -- an 'atom smasher' that recreates the conditions of ...
