Black holes just got darker.
Dark matter is tricky to study because you can't observe it directly — even though it'sof the universe, dwarfing the mere five percent of ordinary, or baryonic, matter that we can see.
In reality, what they observed blew that out of the water: an astonishingly higher rate of one millisecond per year — 50 times the theoretical estimation.Those findings, the researchers suspect, reeked of some dark matter meddling. So to corroborate the hunch, the researchers ran a computer simulation of a dark matter dynamical friction model, which helps calculate the loss of momentum of objects in space due to what is, in effect, "drag" caused by gravity.
"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, an astrophysicist at the Education University of Hong Kong, said in aThe team's findings are some of the best evidence yet of a long-theorized "density spike" near black holes that should form from accreting dark matter.
