The Dark Matter was Found?

Dark matter is out there. Can scientists find it? (Picture from: http://blog.chron.com/)

Approximately 6.8 million positrons and electrons have been detected by the Alpha Magnetic Spectrometer-2 (AMS) on the International Space Station. The detector that worth U.S. $ 2 billion and installed in May 2011 was indeed serve to measure the cosmic ray particles in space.

After examining the AMS results on Wednesday, April 3, 2013, a number of scientists announced the discovery of dark matter, the most mysterious universal material that allegedly make up over 90 percent of the universe's mass.

The AMS is parse around 400 thousand positrons, particles of anti-matter which is the electron pair. Energy emitted by positron showed that the particles may have been formed when dark matter particles collide and destroy each other. The dark matter does not emit light and can not be detected by telescopes. This condition makes it as the unusual material in the universe.

The physicists claim that the dark matter is made from WIMPs (Weakly Interaction from variety Massive Particles) are almost never interact with normal matter particles. WIMP is considered to have its own anti-matter particles that become their partner.

When two WIMPs meet, they annihilate each other, like matter and anti-matter destroy each other when it comes in contact. "The result of a collision between two WIMP will generate positrons and electrons," says Roald Sagdeev, a physicist at the University of Maryland.

Veronica Bindi, a physicist at the University of Hawaii, said the positrons from dark matter will be found at energy levels higher than 10 gigaelektron volts (GeV). This was based on the overflow of positrons as measured by satellite-based detector and called Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics (PAMELA).

Well, the positrons characteristics are detected by AMS in accordance with the positron that measured by Pamela. This was indicated by overflow positron increased 10-250 GeV, the numbers are very likely arise from the collision of the dark matter. *** [EKA | FROM VARIOUS SOURCES | SPACE | MAHARDIKA SATRIA HADI | KORAN TEMPO 4194]
