Why Black Holes Dance Differently ⚡ экспресс
Pairs of black holes dance in three different styles before merging. The first is a neat waltz: the objects swirl in the same direction, like partners facing the same way. Such pairs are born from binary stars and often have unequal masses. The second is chaotic disco: spins are scattered, masses nearly equal. These black holes meet in dense star clusters, where constant close encounters mix everything up. The third dance blends features of both — rapid spins with a wide mass spread.
The first type finishes its dance faster in the early Universe than the second. The reason lies in chemistry: stars poor in heavy elements lose less mass and form black hole pairs more quickly. And the final chord of the merger produces a flare equal to hundreds of supernovae in just an instant.
🎯 The lightest component of a binary black hole ever found weighed only about three solar masses, while the heaviest nearly a hundred. Their dance generates energy comparable to hundreds of supernovae in a split second.
