"Although a black hole will never emit an astronaut or a table or a chair, in practice, it can ...Time slows down in a black hole thanks to a phenomenon known as gravitational time dilation. This time dilation occurs when an immense gravitational field causes a change in the passing of time. Einstein’s theory predicts that the closer you move toward the source of this gravitational pull, the slower time will become.Imagine a fish trying to swim up a waterfall; in a black hole, a light photon “swims” upward as fast as possible (at the speed of light), yet the waterfall of space carries it into the black hole.Russell and his colleagues looked at a well-studied outburst of the black-hole binary XTE J1550-564. The system lies 17,000 light-years away in the southern constellation of Norma and contains a black hole with about 10 times the sun’s mass. The usually inconspicuous binary was discovered by RXTE in 1998, when the system briefly became …Stephen W. Hawking proposed in 1974 that subatomic particle pairs ( photon s, neutrino s, and some massive particles) arising naturally near the event horizon may result in one particle’s escaping the vicinity of the black hole while the other particle, of negative energy, disappears into it. The flow of particles of negative energy into the ...Most holes are the results of unhappy accidents.

Nothing - not even light - can escape. The study of black holes began in the 1930's, when an Indian astrophysicist named Subramanian Chandrasekhar found that there is a limit to how much gravity can be supported by matter as we know it. Nothing here on Earth comes close to exceeding this matter-gravity limit, but the phenomenon often occurs in ...A black hole is a place in space containing an enormous amount of mass packed very tightly together. And it has the capacity to draw in more mass all the time. These objects have so much mass — and therefore gravity — that nothing can escape them, not even light.
