For the first time, scientists have come closer to proving that black holes are surrounded by dark matter. If their theory
What is known
Observations have shown that two stars beginslow down rotation near black holes. Astronomers suggest that the cause is the influence of dark matter, which creates friction. The black holes are called XTE J1118+480 and A0620-00.
It is believed that 85% of our universe is made up ofdark matter. It doesn't interact with light, so scientists can't see it. However, dark matter interacts gravitationally, slowing down other space objects. In our case, we are talking about two stars.
Astronomers turned to the model of dynamicfriction, with which they are trying to get evidence of the existence of invisible matter. Scientists believe that black holes absorb dark matter around them, causing its redistribution and bursts that affect other objects.
The study provides scientists with another waystudying dark matter around black holes. Previously, they focused on gravitational waves and gamma rays that occur during the merger of black holes. Researchers will now focus on finding binary systems to study.
