Black Holes Trivia Questions

Black holes don't actively suck. They have gravity like any other object of their mass. You'd need to get very close to the event horizon to be pulled in.

Black holes vary wildly in size. Stellar-mass black holes can be as small as a city, but supermassive ones can be larger than our entire solar system.

The escape velocity at the event horizon exceeds the speed of light, so no information or matter can get out—hence the name 'black' hole.

This is called 'spaghettification.' The extreme tidal forces from the black hole's gravity pull your feet much harder than your head, stretching you out like a noodle.

It was captured by the Event Horizon Telescope, a global network of radio telescopes, not Hubble. The image showed the supermassive black hole in galaxy M87.

Einstein's equations predicted them, but he didn't name them. The term 'black hole' was coined by John Archibald Wheeler in 1967, decades after Einstein's work.

Due to extreme gravitational time dilation, an outside observer sees time freeze for an object as it approaches the event horizon—it never appears to cross.

Stephen Hawking predicted that black holes emit Hawking radiation, causing them to slowly lose mass and eventually evaporate after trillions of years.
