An international team of astronomers has proved the existence of a ‘gravitational vortex’ around a black hole, solving a mystery that has eluded astronomers for more than 30 years. The discovery will allow astronomers to map the behaviour of matter very close to black holes. It could also open the door to future investigation of Albert Einstein’s general relativity.
Researchers have successfully simulated how a ring-shaped black hole could cause general relativity to break down: assuming the universe contains at least five dimensions, that is.
New window on the universe is opened with the observation of gravitational waves – ripples in spacetime – caused by the collision of two black holes.
A long-sought “echo” of light that promises to reveal more about supersized black holes in distant galaxies has been identified by an international team of astronomers.
