On December 12, 2010, China’s first deep underground ” dark matter” laboratory was put into operation. Speaking of dark matter, do you know what dark matter is?
Astrophysics research found that in the vast space, the mass of luminous stars ( including stars emitting X – rays and gamma rays ) that we can observe is only a small part of the total mass of matter in space. A large part of the quality comes from what we haven’t found out yet. We call this invisible and real thing ” dark matter”.
