Black holes can absorb dark matter - scientists on the cusp of a scientific breakthrough
Scientists have for the first time come close to proving that black holes are surrounded by dark matter. If their theory is proven, a breakthrough awaits us in the study of the mysterious matter and the cosmos as a whole.
Here's What We Know
Observations have shown that two stars begin to slow down their rotation near black holes. Astronomers speculate that the cause is an influence from 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 of dark matter. It doesn't interact with light, so scientists can't see it. But dark matter does interact gravitationally, slowing down other cosmic objects. In this case we're talking about two stars.
Astronomers have turned to the dynamic friction model, which they use to try to provide evidence for the existence of invisible matter. Scientists believe that black holes absorb dark matter around them, triggering its redistribution and surges that affect other objects.
The study provides another way for scientists to study the dark matter around black holes. Previously, they focused on gravitational waves and gamma rays that occur during black hole mergers. Researchers will now focus on finding binary systems to study.
