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.
Personally, I think this has to do with thunderstorms being essentially linear accelerators, vertical SLAC’s if you will. Huge charge differentials from top of cloud to bottom makes for a nice particle slingshot. There’s plenty of opportunity for antimatter (positrons) to be created in energetic collisions from particles coming out of the tops of thunderstorms. [...]

AMESN writes "The Fermi Gamma-ray Space Telescope, launched last year, detects gamma rays from light years away, but recently it detected gamma rays from lightning on Earth. And the energy of the gamma rays is specific to the decay of positrons, which are the antimatter flavor of electrons. Finding antimatter in lightning surprised researchers and suggests the electric field of the lightning somehow got reversed."Read more of this story at...

Fermi telescope finds evidence that positrons, not just electrons, are in storms on Earth.
Designed to scan the heavens thousands to billions of light-years beyond the solar system, the Fermi Gamma-ray Space Telescope has now recorded some more down-to-Earth signals. During its first 14 months of operation, the flying observatory has detected 17 gamma-ray flashes associated with terrestrial lightning storms.
The flashes occurred just before...

The overlap with the title of this blog, Matter/Antimatter, is completely coincidental, but since most meaningful events are coincidental, it makes perfect sense that it prompted San Francisco-based conceptual artist Jonathon Keats to send me a note pointing to his upcoming exhibition "The First Bank of Antimatter."...

In a new exhibit opening in just a few weeks, conceptual artist Jonathon Keats will propose an antimatter-based mirror economy designed to boom as the regular-ole economy continues to tank. "Economic equilibrium is upset by our unbalanced pursuit of material wealth," says the artist. "My plan is to offset materialism with modern science, by exploiting the economic potential of antimatter, which is the physical opposite of anything made with...
