When black holes merge, what happens inside of them is anybody's guess. Black hole mergers are beautiful — and some of the most violent events in the cosmos. Here's how the process unfolds.

Stellar-mass black holes typically form after a star goes supernova and collapses. However, the discovery of the first-ever triple black hole system, V404 Cygni, complicates that picture. This black ...
