• •Through a process known as superradiance, dark matter could steal energy from a rotating black hole.
• •The emitted dark matter would ring space-time like a bell around the black hole.

The researchers say that dark matter could steal energy from a rotating black hole, and that this would cause the black hole to slow down. The released dark matter would then ring space-time like a bell, and this could be detected by experiments in the solar system.
