AMS has found evidence of dark matter

[] Lahore, Pakistan – The space instrument Alpha Magnetic Spectrometer (AMS-2) has discovered the first evidence for dark matter in the universe. Dark matter, which shall consist of more than a quarter of the universe, could not yet be detected.

The measurement tool that sits on the outside of the ISS (International Space Station, ISS) examines the particles of cosmic radiation. AMS was found in the first year and a half about 400,000 positrons, the researchers explained by Samuel Ting at a seminar at the European Organization for Nuclear Research CERN in Geneva .
Largest amount of antimatter particles

That was the largest so far detected amount of antimatter particles, reported Ting. So far, researchers on Earth in particle accelerators artificially antimatter, about antihydrogen or anti-helium . It emerged, however, only a few antiparticles.

The positron is a positively charged elementary particle that is the antiparticle to the electron. Hit a positron and an electron each other, they annihilate each other . The positrons have an energy 0.5 to 250 giga-electronvolts (GeV), where the majority have yet situated in the range between 20 GeV and 250 GeV, the researchers write in the journal Physical Review Letters .
Particles and antiparticles in a

The positrons could be an indication of the dark matter: dark matter is supposedly out of the so-called wimps – an abbreviation for Weakly Interacting Massive Particles (weakly interacting massive particles). These particles should be their own antiparticles – that brings together two wimps, they will annihilate each other, giving rise positrons and electrons.

The data collected by the AMS-2 showed no significant fluctuations over time and there is no preferred direction from which the positron came. This could be an indication that they are the waste product of the annihilation of dark matter particles.
Pulsar origin?

The researchers, however, are cautious. The positrons may also be other causes, come about from pulsars, they said. “In the coming months we will AMS say convincingly to whether these positrons are an indication of dark matter, or whether they have a different origin,” said Ting.

Dark Matter is more than a quarter of the universe. So far it has yet to be observed directly, but only through their interaction with visible matter. She is considered “one of the biggest mysteries of physics”.

The AMS-2 is examined, a detector, the incoming charged particles such as protons or electrons. A magnet that draws on different detectors, which detect what type of particles are involved, such as protons or electrons whose energy, charge and mass as well as the direction from which they came, so that researchers can determine its origin. So far, AMS has captured around 25 billion particles and examined before they could come up with the earth’s atmosphere interact in contact.

The instrument is attached to the ISS. It was in May 2011 from the space shuttle Endeavour brought to the ISS was. It was the last flight of Endeavour and the penultimate space shuttle missionNew Technology
