China may have really discovered dark matter: rewriting physics textbooks

The data show that there are "new physical particles with a mass of about 1.4 trillion eV" in space. Scientists speculate that it may be the dark matter people have long been looking for! This is the first time since the successful launch of the "Wukong" in 2015 that the Chinese used their own satellites for the first time in the world may have discovered dark matter.

In today's universe, we have only figured out 5%, and 95% of these invisible dark matter and dark energy.

Goku is aimed at this frontier and has conducted exploratory work in space. According to current theoretical physicists, if dark matter particles collide with each other and annihilate, they will be converted into high-energy electrons. Then to space to accurately detect high-energy electron spectroscopy, you can find the existence of dark matter clues.

Dark matter particle detection satellite, is actually a telescope. High-energy photons and detectors produce positive and negative electron pairs, which detect the direction and energy of high-energy photons in the sky by detecting the direction and energy of the positive and negative pairs. Each high-energy particle hit, can produce more than 70,000 signals.

The "Goku" was launched at the end of 2015. The performance is working normally. The entire detector has 1.4 tons of multiple power consumption of 600 watts. It operates on a 500-kilometer solar synchronous orbit with energy, direction, and charge, including particle identification Aspects, have reached the highest level in the world.

With 530 days and nights of record, scientists have finally found some signs they had never predicted before: a spike in energy at 1.4 trillion eV!

Scientists speculate that this anomaly comes from the "new physical particles of about 1.4 trillion eV" in the universe. It may be dark matter that has long been sought, or something peculiar, that accelerates a single energy high-energy electron.

This is a groundbreaking discovery in the field of particle physics or astrophysics! Just as Chang Jin, chief scientist of the Dark Matter Particle Exploration Satellite and the deputy director of the Purple Mountain Observatory of the Chinese Academy of Sciences, said: "We hope that in the near future the Chinese will find dark matter particles in the sky!"

See here, maybe we still do not know what is dark matter? The following Xiaobian take you to understand this magical material.
