what do u mean by black hole friction which kind of hole we need to reduce black hole to alpha hole give universal eg of black hole friction?
Answers
Answer:
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.
The only friction a particle would experience is due to its emission of gravitational radiation as it moves through the curved spacetime generated by the black hole. ... The idea that black holes suck anything in is the biggest myth about them. They grow due to gravitation, and nothing more.
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.
