We may have accidentally detected dark matter back in 2019. This potentially history-making discovery could be lurking in existing data from gravitational waves – ripples in the fabric of spacetime itself. Physicists from the US, UK, and Europe propose that if two black holes happened to collide while enveloped in a cloud of dark matter, the gravitational waves they send across the cosmos could carry the imprint of that environment. When they applied their model to dozens of gravitational wave
