Black holes are regions in spacetime with such strong gravitational fields that nothing can escape their boundaries, not even light. As a result, most of these massive objects invisibly drift through space, making it difficult to resolve the many open questions about their mind-bending properties.
Now, scientists have suggested there may be a way to confirm a key mystery about black holes—whether they produce vortex structures—by searching for specific signatures in space. These vortexes would be structurally similar to the swirling maelstroms of tornadoes and whirlpools, but they would arise in multiple places on black holes instead.
In addition to shedding light on black holes, these clues could potentially open “an observational window to various hidden sectors” of the universe, including the nature of dark matter, according to a recent study published in Physical Review Letters.
