you go to a hole that's black and tell people about it.
Well, obviously, if it formed a certain time ago. But I don't think you can tell the age of a black hole just by looking at it.
The universe is expanding but I'm not too sure about the second part. The obvious thing is that a black hole looks like a big black hole.
Astronomers look for black holes by searching for their effects (the hole itself by definition can't be seen). Some of the possible effects are gravitational lensing and electromagnetic radiation from the hole's accretion disk.
Nobody went to any black hole, I can tell you that. If anyone were to go into one, they would be spaghettifyed! Also, if anyone made it into a black hole and went down all the way and came back out to live to tell the story, they'd go down in history.
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

A black hole originated as a star, that is, the star converted to a black hole.
I dont know when it formed but i must tell you that 1400 years back eaarth has gone in the black hole just go through the holy book quran you will get to know everything.
If you fall into a black hole, you'll go into the black hole and nowhere else.
In a black hole, gravity is so strong that nothing, not even light, can escape. This means that whatever goes into a black hole is trapped inside forever, making the saying "what happens in a black hole stays in a black hole" true.
probs black hole
Black hole is a location in space that possesses so much gravity, nothing can escape from its pull. Yes, Super massive black hole is the largest black hole.
