Astronomers have detected material *just* over the edge of a black hole’s Point Of No Return.
Nope. The motion was detected *directly*. In other words: They. Saw. The. Dust. Clouds. Move.
How? Because that material is moving at 30% OF THE SPEED OF LIGHT.
Wanna fly from LA to NYC at that speed? It’ll take 0.06 seconds. You could make 8 round trips like that in one second. You could get to the Moon in four seconds at that speed.
