Ever since antimatter was first seriously theorized by physicist Paul Dirac in the late 1920s, it has been accepted ---- in mathematical formulations and in subsequent observation that confirmed its existence ---- that antimatter is identical to normal ...

Boffins spin up positronium
A group of researchers at University of California Riverside hopes to chip away at one of physics’ ‘question of questions’ – why the blazes we’re here at all. Their hope is to make electron/positron pairs live long enough to measure the positron’s mass and find out if it’s different to the electron.…

If a positron and electron encounter each other, they annihilate to produce two gamma rays. Physicists David Cassidy and Allen Mills first separated the positron from the electron in positronium so that this unstable system would resist ...

A community portal about Antimatter with blogs, videos, and photos. According to Wikipedia.org: In particle physics, antimatter extends the concept of the antiparticle to matter, wherein if a particle and its antiparticle come into contact with each other, the two annihilate —that is, they may both be converted into other particles with equal energy in accordance with Einstein's equation E = mc 2. This gives rise to high-energy photons or other particle–antiparticle pairs. The resulting particles are endowed with an amount of kinetic energy equal to the difference between the rest mass of the products of the annihilation and the rest mass of the original particle-antiparticle pair, which is often quite large.
