CERN scientists record traces of dark matter.

Scientists at the European Organization for Nuclear Research (CERN) said on April 3 that they may have detected traces of dark matter, a substance believed to make up a quarter of the universe but which humans have previously been unable to see.

Thanks to the Alpha Magnetic Spectrometer (AMS) installed on the International Space Station (ISS) two years ago, CERN scientists have made progress in studying this mysterious matter.

The AMS instrument has recorded an excess of positrons (the antiparticle of an electron) in cosmic rays.

Over the past year and a half, this $2 billion AMS machine has collected information on 25 billion particles, including 400,000 positrons with energies ranging from 0.5 to 350 GeV (Giga Electronvolt).

This is the largest amount of antimatter ever detected in the universe.

According to Samuel Ting, the lead researcher for the AMS experiment and winner of the 1976 Nobel Prize in Physics, the AMS will soon provide the final answer as to whether positrons are evidence of the existence of dark matter, or whether positrons are the source of something else.

CERN is the world's largest fundamental particle physics laboratory, located on the French-Swiss border.

Established in 1954, CERN analyzes information collected by the AMS instrument on the energy spectrum of primary cosmic rays.

Confirming the theory of the existence of dark matter could open a new chapter in the study of the universe and may soon provide answers to the question of how the universe was created.

Dark matter does not emit or reflect enough electromagnetic radiation to be observable with telescopes or current measuring instruments, but it can be detected because of its gravitational effects on solids or other objects, as well as on the universe as a whole.

Weighing nearly 7 tons and costing $2.5 billion to build, the AMS instrument is the first magnetic field spectrometer to be sent into space.

Besides the AMS detector, there is currently another device that indirectly detects dark matter: the Neutrino Astronomical Observatory in Antarctica.

This observatory tracks neutrinos, which are formed when dark matter passes through the Sun and interacts with protons.
