Black hole singularities
WebMar 29, 2024 · Physicists are using quantum math to understand what happens when black holes collide. In a surprise, they’ve shown that a single particle can describe a collision’s entire gravitational wave. An entire gravitational wave can be known through the behavior of just one of its countless particles. When two black holes collide, the titanic ...
