Black hole collisions may follow entropy law, offering simpler remnant predictions

When two black holes orbit each other, they eventually spiral inward and collide in one of the most violent phenomena in the universe.

The event is so energetic that it significantly distorts the universe around it.

It emits gravitational waves—ripples in the fabric of spacetime—that are strong enough to be detected with precision instruments on Earth even when they originate billions of light-years away. ...
