The first strong black hole candidate observed was in an x-ray binary system in constellation Cygnus and is called Cygnus X-1 (so named because it was a strong x-ray source). Observational evidence continues to support the notion that it could only be a black hole; its mass is estimated at a little under 15 times the mass of our sun, with a Schwarzschild radius of about 44 km.
black hole got it's name because when look at a black hole, you only see black. also if you drop an item in the black hole the item is gone because there is a hole in there. so that's how black hole get's its name
they are black and their bottomless!
No non-fiction person has ever gone into a black hole.
The idea of a black hole was first enunciated by physicist John Michell in a letter published in 1783. Later, the term "black hole" was coined by physicist John Archibald Wheeler in 1967.
The first black hole candidate to be discovered is Cygnus X-1, which was identified in 1964. It is located in the constellation Cygnus and is one of the most studied black hole candidates due to its strong X-ray emissions.

The first black hole was probably after the first population III star exploded about 13.1 billion years ago. One of which might be the black hole at the centre of our galaxy.
The term "Black hole" first appeared in print in an article by Ann Ewing in "Black Holes in Space" published in 1964.

You can't - that's the whole idea of a black hole. Don't get near a black hole in the first place.
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.

noone can go black hole as the name suggest it is a hole which is black so how any one can go ad com back...

As far as we know, most, if not all galaxies have a massive black hole at their centre.
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.
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.
