About Black hole By Kota Katsunuma

What are black holes ?   Scientists think a black hole form when a supergiant star Colipases form the force of its own gravity. It leaves

John Archibald Wheeler Who Is said black hole ? John Archibald Wheeler  He is American scientist

How many kinds of black hole ? Stellar black hole supermassive black hole Miniature black hole

Stellar black hole Stellar black hole, with masses less than about 100 times that of the sun, comprise one of the possible evolutionary, endpoints, of high mass stars.

supermassive black hole Supermassive black holes, which can have a mass equivalent to billions of suns, likely exist in the centers of most galaxies, including our own galaxy, the Milky Way.

Miniature black hole miniature black hole, which would have a mass much smaller than that of our Sun. But it's possible that miniature black holes could have formed shortly after the "Big Bang," which is thought to have started the universe 13.7 billion years ago.
