Scientists will announce the latest achievements on dark matter discovery


According to foreign media reports, scientists are currently preparing to announce the latest achievements in the discovery of dark matter, which originated from the data acquisition of the Alpha Magnetic Spectrometer particle detector of the International Space Station. As early as May 2011, the Space Shuttle Endeavour sent $ 2 billion worth of scientific instruments to the ISS, bringing together the power of more than 60 research institutions in 16 countries and collecting a total of 7.7 billion electronic and positron data. At the same time, the researchers hope to determine whether the number of antimatter particles is greater than that of ordinary matter particles. If this conjecture is consistent with the facts, the gap between energy levels will be reflected.

The Alpha Magnetic Spectrometer is a particle detector installed on the ISS. It is designed to explore dark matter and antimatter in space and collect special particles such as electrons, positrons, and antiprotons accompanying cosmic rays. According to Michael Turner of the Caffery Institute of Astrophysics at the University of Chicago: "What we are looking for is the ratio of positrons to electrons. Scientists believe that there is hidden information about the annihilation of dark matter and the density of dark halos." There is a mysterious structure in the center between 100,000 and 300,000 light years. Here, researchers believe that there are a large number of dark matter components with huge masses. Most of the total mass of the galaxy is composed of these dark matter.

According to the current dark matter model, the distribution of dark matter in the periphery of the Milky Way may extend to a span of 1 million light years, while the diameter of the Milky Way is about 100,000 light years. Hidden behind the data of the Alpha Magnetic Spectrometer (AMS) is the mystery that has plagued the scientific community for more than 80 years, and can answer the reason for the disparity between the mass of ordinary matter and the mass of invisible matter in the universe. Physicists estimate that ordinary matter in the universe, such as galaxies and stars, account for only 4% of the total mass, the other 24% is dark matter, and the rest is dark energy. There are not only machines to find dark matter, there are large hadron colliders, etc., but no dark matter particles have been found so far. European scientists hope to upgrade the colliders and obtain higher energy two years later.
