How magnetic fields, like brakes, control the mass and spin of black holes, explaining the strange findings of gravitational wave detectors.

Two black holes merge, each with a mass and spin that shouldn't exist. New simulations show: magnetic fields act as cosmic brakes — strong fields slow the spin, weak ones whip the hole up to mind-boggling speeds. The discovery explains the heaviest gravitational-wave find.

🎯 It was once thought that the core of a star with 250 solar masses would explode without a trace. It turns out it can produce a black hole.

🎬 Such a rapidly spinning hole is almost like Gargantua from Interstellar: extreme rotation and monstrous gravity.
