When was the first black hole?

No one has gone to a black hole.

No. The idea of a black hole was first proposed in 1783, 230 years ago. The first observations believed to indicate the presence of a black hole were in 1964.

No non-fiction person has ever gone into a black hole.

Cygnus X-1 was discovered in 1972. This is very likely a black hole.

As a black hole.

Nobody has ever visited a black hole. The nearest known black hole is many light years away. Much to far away for us to reach it.

Yes, a black hole can believe it or not, eat another black hole.

no one did, you cannot see black holes.

It was discovered in 1972.

First of all, our sun can not become a black hole, it is too small for that. However if a star is three times bigger than our sun, then yes it will become a black hole.

First, it isn't the "weight", but the mass of the black hole that is relevant. Second, the black hole does, indeed, greatly distort space and time in its neighborhood.

Yes. Matter falls into black holes all the time; the first known black hole was the "Cygnus X1" black hole, which was discovered by the X-ray emissions caused by matter being pulled off the companion star and falling into the black hole.

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.

The oldest black hole will be the first black hole ever created. Know one knows when that was but it would have been after the first population III star exploded as a supernova. This would put it around 13 billion years old.

No black hole has ever been seen by anyone. The nature of a black hole actually prevents it from being seen. A black hole is the ultimate gravity well, and nothing that crosses the event horizon can escape. Not even light can get out. The only way a black hole can be "seen" is indirectly as it creates what is called gravity lensing. Light from objects "behnid" the black hole is "bent" around it, and it is this phenomenon that allows a black hole to be "seen" by observers.

The ending first: We don't know. Please re-read that. OK, what are the conjectures? A Black hole leads to another, somewhat parallel universe. A Black Hole leads "nowhere". A Black Hole leads to a different type of singularity. A Black Hole leads eventually to another "Big Bang" in another dimension. A black hole leads to a parking lot in Gelsinkirchen, Germany. There are many more. Please re-read the first sentence.

By a Star collapsing on its self.

There are two types of black holes. There is an ordinary black hole and there is a Kerr Black Hole.

you can't get out of an black hole

A black hole originated as a star, that is, the star converted to a black hole.

Black holes can't be seen directly, but there is strong evidence that certain X-ray emissions are caused by black holes. The first really good candidate to be considered a black hole was Cygnus X-1. This was discovered in 1964, but only about ten years later did scientists think it could be a black hole. It was about 1990 that most scientists decided it really must be a black hole.

Yes. Such things can and do happen. Of course, the sun/star must get close enough to the black hole in the first place.

Yes. Intermediate-mass black hole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassive black hole it will need to go though this stage of intermediate-mass black hole.
