Turbulent spacetime and destroyed stars help reveal how fast supermassive black holes spin

The “shaking” remains of a star that suffered a grisly death at the maw of a supermassive black hole have helped reveal the spin rate of the cosmic predator. Supermassive black holes are believed to be born through successive mergers of smaller black holes; Each of these brings with it angular momentum that accelerates the… Read More »

‘Quantum tornado’ allows scientists to mimic a black hole on Earth

Thanks to their enormous gravitational forces, the regions around black holes are violent and turbulent environments driven by physics that cannot be found anywhere else in the universe. In fact, black holes are so effective that when they rotate, they drag the fabric of space with them. In other words, nothing remains stationary near a… Read More »
