The term Black Hole is coined by American Astronomer ''John Wheeler'', in 1967. The First Black Holes was discovered in 1971.
Black Holes are the Strangest and the most powerful objects found in Outer space which have the extremely high Density with such strongest gravitational force that no other object even Electromagnetic radiations cannot escape from their gasp if it comes near enough.
Generally Black Holes [As per as research in Universal Science] are of three types-
@---Stellar Black Holes.
@---Supper massive Black Holes.
@---Intermediate Black Holes.
Also, In easy terms, Black whole is defined as ''An imaginary place where objects,files or light go when lost for no apparent reason''.
~~In our Milky Way Galaxy [ Also known as Akash Ganga], there are many Black holes which cannot be count. It is just like counting grains of the sand in the beach or counting the stars in the sky.
We do not know much about Black holes, because the research is going on the mysterious Black Hole. It may be complete in near Future.
~~Stephen Hawking was one of the greatest scientists who has solved some of the mystery of the Black Holes.
The Book '' Black Hole and Baby Universe'' and '' The Brief History of time'' which are written by the Stephen Hawking is all related to to the Black holes and gives whole account [which has been proved by the research] of it.
The Milky Way[a] is the galaxy that contains the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. THE Universe s everything we can touch, feel, sense, measure or detect. It includes living things, planets, stars, galaxies, dust clouds, light, and even time. Before the birth of the Universe, time, space and matter did not exist.
The universe city contain billions of
Galaxy each containing millions or billions of stars. The space between the stars and galaxies is largely empty. However, even places far from stars and planets contain scattered particles of dust or a few hydrogen atoms per cubic centimeter. Space is also filled with radiation (e.g. light and heat), magnetic fields and high energy particles (e.g. cosmic rays).

The Universe is incredibly huge. It would take a modern jet fighter more than a million years to reach the nearest star to the Sun. Travelling at the speed of light (300,000 km per second), it would take 100,000 years to cross our Milky Way galaxy alone.
No one knows the exact size of the Universe, because we cannot see the edge – if there is one. All we do know is that the visible Universe is at least 93 billion light years across. (A light year is the distance light travels in one year – about 9 trillion km.)
The Universe has not always been the same size. Scientists believe it began in a Big Bang, which took place nearly 14 billion years ago. Since then, the Universe has been expanding outward at very high speed. So the area of space we now see is billions of times bigger than it was when the Universe was very young. The galaxies are also moving further apart as the space between them expands.

in class 6th i have bought one bool named universe so i want to share some information for that
Explanation:
bkack hole is the place where any particle cannot escape because of some gravity pullness. And we cant see the black hole beacuse it do not escape light also
