Question

what is black hole? what happens in black hole​

Answer 1

Answer:

Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or "stuff," in an object.

Another kind of black hole is called "stellar." Its mass can be up to 20 times more than the mass of the sun. There may be many, many stellar mass black holes in Earth's galaxy. Earth's galaxy is called the Milky Way.

➡️A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

➡️Black holes are generally defined as "a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because [the] matter has been squeezed into a tiny space." - NASA. As light is unable to escape the hole's gravity it appears completely black - hence the name.
