Though gold and diamonds are precious materials, they're nowhere near the most expensive thing in the universe. In fact, the ...

Antimatter is a natural product of some types of radioactive decay and cosmic ray collisions, but it can also be made in particle colliders here on Earth. But making antimatter particles this way is ...

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.

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 ...

Researchers say comparing characteristics of matter and antimatter particles generated in these particle collisions can offer clues to why that asymmetry happened. “To study the matter-antimatter ...

It is a so-called exotic atom consisting of both matter and antimatter - so very unusual stuff indeed. Matter is what the world around us is made from, including the stars, the planets and us ...

Frozen antimatter study to 'alter our understanding' of the universe. Researchers have for the first time slowed down an antimatter atom using lasers to more precisely study this physical phenomena.

To be sure, antimatter was not known about when Einstein published his general theory in 1915. It was discovered only in 1932. But the general theory treats all matter as identical, which would ...

Antimatter is the mirror version of every particle in the universe. For the last 100 years, ... The only “one of the horizon” was the antihydrogen atom, says Joel Fajans, ...
