Chinese researchers seek the secrets of dark matter during the early life of the universe

Chinese astronomers plan to use the world’s largest radio telescope to discover the secrets of dark matter and study the early age of the universe.

According to Tekna technology and technology news service, early galaxies had the feature of light absorption by hydrogen around them. This feature will help scientists uncover the secrets of dark matter.

According to scientists, the formation of early galaxies was caused by dark matter. Therefore, they seek to discover the mystery of the role of dark matter in this formation. Because this substance has nothing to do with light and how it interacts with early galaxies remains unknown.

Northeastern University scientists will begin building a probe in collaboration with the National Astronomical Observatory of China to investigate the dimensions of this issue. One of the methods of investigating dark matter is the study of small structures in the universe. This investigation should be done at a time about 380 million years after the big bang and in a period called Cosmic Dawn. At that time the first stars were born. At that time, atoms were in the form of gas and made of hydrogen. This element is able to absorb hydrogen in all wavelengths of light. It also leaves its mark on the light after passing through.

This atomic gas creates lines of several centimeters around the primary structures of the universe and in the radio range of the electromagnetic spectrum. These lines can be used as a set to probe dark matter and probe gas temperature.
