What is a black hole ?
A black hole is a region of space where gravity is very strong that even light also can't escape. Because stuff has been crammed into such a small space, gravity is extremely powerful. When a star is dying, this can happen.
People can't perceive black holes since no light gets through. They are undetectable. Space telescopes equipped with specialised equipment can aid in the discovery of black holes.

What Causes Black Holes to Form?
Stellar black holes are formed when the core of a massive star collapses in on itself. When this happens, a supernova occurs. A supernova is a star that explodes and sends a portion of its mass into space.
The smallest black holes, according to scientists, formed when the universe began.
Supermassive black holes, according to scientists, were created at the same time as the galaxy in which they reside.
What Is the Size of Black Holes?
Black holes can be very large or very small. The smallest black holes, according to scientists, are as small as one atom. These black holes are really small, but they have the bulk of a mountain. The amount of matter, or "stuff," in a thing is measured in mass. "Stellar" black holes are a different type of black hole. It has a mass that is up to 20 times that of the sun. In Earth's galaxy, there could be a large number of star mass black holes. Our galaxy name is "milky way"
"Supermassive" black holes are the largest. These black holes have a combined mass of more than a million suns. Scientists have discovered confirmation that at the heart of every giant galaxy is a supermassive black hole. Sagittarius A is the name of the supermassive black hole in the centre of the Milky Way galaxy.
