Strange matter Illustration of how antihyperhelium-4 – a bound state of two antiprotons, an antineutron and an antilambda – is created in lead–lead collisions at CERN. (Courtesy: CERN/ J Ditzel with ...

Since its basic “anti-ness” was not changed by the loss of its charge, it became an antineutron with a reversed magnetic field. If an antineutron hits a neutron, both turn into energy.

Scientists first predicted the existence of antimatter in 1928, and discovered it in 1932. The first simple antimatter nucleus (an antiproton stuck to an antineutron) was discovered a few decades ...

At the moment physicists are having enough difficulty just taming antihydrogen, the simplest possible anti-atom. Can we ever expect them to make a whole anti-periodic table?

Physicists working in the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC) at the Brookhaven Laboratory in the US have detected antimatter nuclei containing strange quarks for the ...
