What are Black Holes?
Imagine the whole mass of a star more than one million times than that of our sun collapsed into an object of nearly zero volume it means that it is even smaller than an electron (Planks length), as a result, the laws of physics do not apply on it and quantum theory applies on it. So, According to you What will be its density? The answer to this question is infinite. The density of a black hole is infinite. But, its mass is not infinite it is finite.
The event horizon is a point near the black hole from where nothing, not even light can escape. It is called the "point of no return".
Black holes are not completely black but there is a ring of light around them which contains light this ring is made of electromagnetic radiation popularly knows as Hawkings Radiation.
This is a picture of an actual black hole released by the event horizon telescope. It is the picture of the supermassive black hole located in the centre of the galaxy Messier 87.
Theories suggest that if a person can walk between two black holes of any mass close to each other, The person can go back in time. So, black holes can be used as time machines in the distant future.
Stars can orbit around a black hole. Even our sun is orbiting a supermassive black hole named Sagitarus A which is at the centre of our Milky Way galaxy.
Due to Hawkings Radiation, it is proved that a black hole loses its mass as a result eventually the black hole will die leaving behind nothing not even a sign of its existence.
