Back in 2019, the gravitational wave observatories LIGO and Virgo detected major ripples in spacetime. While astronomers generally agree that the event, dubbed GW190521, was the result of two black holes colliding, a team of researchers at the Chinese Academy of Sciences has proposed a far more eyebrow-raising explanation. As detailed in a yet-to-be-peer-reviewed paper, first spotted by ScienceAlert, the researchers suggest that LIGO and Virgo instead picked up the signals of a black hole collision in a different universe than ours.

Everything is unusual about this galaxy. Not only does it look very strange, but it also has this supermassive black hole that's pulling a lot of material in.
