$\sf \large Black \: Hole$

$\bullet$ A black hole is a region of space time exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it.

$\bullet$ A black hole is a region of space from which nothing, including light, can escape. According to the general theory of relativity, it is the result of the curving of spacetime caused by a huge mass.

$\bullet$ Around a black hole there is a position of no return, called the event horizon.

$\bullet$ It is called "black" because it absorbs all the light that hits it, reflecting nothing, just like a perfect black body in thermodynamics.

$\bullet$ Under the theory of quantum mechanics black holes have a temperature and emit Hawking radiation, which makes them slowly get smaller.

$\bullet$ A black hole is found by its interaction with matter.

$\bullet$ The presence of a black hole can be inferred by tracking the movement of a group of stars that orbit a region in space.

»» Black Holes are the most mysterious objects in space. They have so much powerful gravitational field around it. Black holes are formed from a blue stellar star, in their later years, stars collapsed in their core as the fuel of star that is hydrogen is already used up...Then, there is only left heavy elements like :- iron, platinum and many heavier elements. After the collapse, there left very small central part of star that is event horizon... Event horizon is the inner part of a black holes, in that part, there is so high or we can say infinite gravitational force that even light can't escape from that part of black hole.

»» Black holes are mainly of 3 types

=> Interstellar black holes

=> Supermassive black holes

=> worm holes
