HUGE PRODUCTION OF ANTIMATTER PLANNED

HUGE PRODUCTION OF ANTIMATTER PLANNED | Antimatter | Scoop.it
WORKING round the clock under an Illinois prairie, physicists are preparing to switch on the world's largest factory for the production of antimatter, the rare and baffling particles that exist as shadowy mirror-images of all the subatomic...

Physicists discover new way to produce antimatter-containing atom

Physicists discover new way to produce antimatter-containing atom | Antimatter | Scoop.it
Physicists report that they have discovered a new way to create positronium, an exotic and short-lived atom that could help answer what happened to antimatter in the universe, why nature favored matter over antimatter at the universe's creation.

Antimatter is so tantalizing a prospect for propulsion that every time a new slant on using it appears, I try to figure out its implications for long-haul missions.

“Surely something is wanting in our conception of the universe. We know positive and negative electricity, north and south magnetism, and why not some extra terrestrial matter related to terrestrial matter, as the source is to the sink.

Matter-Antimatter Power on Star Trek

Aboard the famed Starship Enterprise from the television series Star Trek the propulsion systems are energized by a matter-antimatter power plant. Is such a thing even possible? Could we ever build such a device and use it to power starships?

Antimatter - Wikipedia, the free encyclopedia

Antimatter

In particle physics, antimatter is material composed of antiparticles, which have the same mass as particles of ordinary matter but have opposite charge and quantum spin. Antiparticles bind with each other to form antimatter in the same way that normal particles bind to form normal matter. For example, a positron (the antiparticle of the electron, with symbol e+) and an antiproton (symbol p) can form an antihydrogen atom. Furthermore, mixing matter and antimatter can lead to the annihilation of both, in the same way that mixing antiparticles and particles does, thus giving rise to high-energy photons (gamma rays) or other particle–antiparticle pairs. The end result of antimatter meeting matter is a release of energy proportional to the mass as the mass-energy equivalence equation, E=mc2 shows.[1]

There is considerable speculation as to why the observable universe is apparently composed almost entirely of matter (as opposed to a mixture of matter and antimatter), whether there exist other places that are almost entirely composed of antimatter instead, and what sorts of technology might be possible if antimatter could be harnessed. At this time, the apparent asymmetry of matter and antimatter in the visible universe is one of the greatest unsolved problems in physics.[2] The process by which this asymmetry between particles and antiparticles developed is called baryogenesis.
