For the first time, scientists may have discovered indirect evidence that large amounts of invisible dark matter surround black holes. The discovery, if confirmed, could represent a major breakthrough in dark matter research.
Fortunately, dark matter does interact gravitationally, enabling researchers to infer the presence of dark matter by looking at its gravitational effects on ordinary matter"proxies." In the new research, a team of scientists from The Education University of Hong Kong used stars orbiting black holes in binary systems as these proxies.
"This is the first-ever study to apply the 'dynamical friction model' in an effort to validate and prove the existence of dark matter surrounding black holes," Chan Man Ho , the team leader and an associate professor in the Department of Science and Environmental Studies at EdUHK, said in a statement .
