can anyone define me blac hole and how does they work?
Answers
Answer:
A black hole is a region of spacetime exhibiting gravitational acceleration 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.
In short, black holes are massive pits of gravity that bend space-time because of their incredibly dense centers, or singularities.. When a star dies, it collapses inward rapidly. As it collapses, the star explodes into a supernova—a catastrophic expulsion of its outer material. The dying star continues to collapse until it becomes a singularity—something consisting of zero volume and infinite density. It is this seemingly impossible contradiction that causes a black hole to form.
hope it will help you ❤️❤️❤️
