How do black holes work.
The Black Hole Is the Atom of the Twenty-First Century. “From the perspective of gravity, [a black hole] is the simplest object we know of, no more than a hole in space. At the same time, according to quantum theory, it is the most complex object, the most compact way to store matter and information.”.

If you take an hour period, it's probably going to ...Dec 16, 2014 · The black hole does "leak" information, but it is not due to "gravitions, but in the form of the Hawking radiation. It has its basis in quantum mechanics, and is a thermal sort of radiation with extremely low rate. This also means that the black hole is slowly evaporates, but on a time scale that is comparable to the age of the universe. Black holes are massive pits of gravity that bend space-time because of their incredibly dense centers, or singularities. They form when a star dies and collapses into a singularity. The inside of a black hole is …Apr 13, 2015 · Then they’ll slowly radiate heat away, which must come from the black hole converting its mass into energy.
