On the 16th of US Eastern Time, multi-national scientists participated in the project. The project invested 2 billion U.S. dollars in space particle detectors—the Alpha Magnetic Spectrometer 2 was launched on the space shuttle Endeavour. As the largest scientific instrument to be installed on the International Space Station, scientists expect it to help reveal the mysteries of the origins of the universe.

According to the Big Bang Hypothesis, our universe was formed by a very small point explosion about 14 billion years ago. The universe produced matter and it also produced antimatter. The amount of the two is roughly the same, and the "substance" is a little more. Although the existence of the current material is obvious, the evidence for the existence of antimatter is only a fleeting fleeting amount of antiparticles observed in the laboratory. Scientists believe that anti-matter cannot exist in the Earth's environment because once it encounters matter on Earth, the two will annihilate, but antimatter may exist in space. Therefore, the team led by Nobel Laureate and chief scientist of the Alpha Magnetic Spectrometer Project, Professor Ding Yizhong, hopes to discover the anti-material and dark matter traces through the observation of magnetic spectrometers in space to explore whether there is an anti-universe.

Dark matter is an invisible substance in the universe, that is, it does not emit visible light or other electromagnetic waves. It cannot be observed with astronomical telescopes. However, dark matter also produces gravitational pull, which has an effect on visible matter. Based on existing hypotheses and observations, scientists estimate that dark matter accounts for more than 90% of the total mass of the universe.

The main strength of Alpha Magnetic Spectrometer is based on its powerful and special magnetic field. After the charged particles enter the magnetic field, the trajectory will change, and the trajectory of different charged particles will change, and the trajectory of the non-charged particles will not change. Therefore, whether or not the trajectory changes after the observation of the particles enters the magnetic field is different. It can be inferred what kind of particles this is. Unlike visible light and electromagnetic waves emitted by observing substances from astronomical telescopes, magnetic spectrometers directly observe the particles themselves. Therefore, magnetic spectrometers can detect dark matter and antimatter that cannot be found by astronomical telescopes.
