While it's generally accepted that since the escape velocity of a black hole exceeds the speed of light, the region behind a black hole's event horizon is hidden or separate and no light from within can escape, there does seem to be a mechanism by which black holes can interact thermodynamically with the universe similar to black-body radiation wherein the apparent temperature of the black hole inversely proportional to its mass. One description is that quantum fluctuations near the event horizon, boosted by gravity, can generate particle pairs, one of which can escape the vicinity of the black hole and thus carry away energy and thus decrease its mass. By this mechanism a black hole could eventually 'evaporate', with the rate of evaporation increasing as the mass decreases. This 'Hawking Radiation' takes its name from the scientist that famously proposed its existence. Another description of radiation from black holes, presented by Professor Hawking himself, appealed to Heisenberg's uncertainty relation: which states that the more accurately you know the position of a particle, the less accurately you can know its velocity; as a black hole decreases in size you would more and more accurately know its location inside the black hole and thus its velocity could increase until it exceeded 'c' and could therefore escape the black hole.
What else can I help you with?
What does the black hole not give off that they can't be seen?
Black holes cannot be directly observed because they do not give off any radiation (including light). Instead, they are detected based on indirect evidence, such as the effect of the black hole's gravitational interaction with it's surroundings.
How does pulsar become a black hole?
A pulsar will not become a black hole because they do not implode and that is one of the key features of a star becoming a black hole. a pulsar is highly magnetized and gives off a beam of electromagnetic radiation, when viewed from a distance it will look as though it is flashing.
What is the difference between a black hole and a quasar?
A quasar is a galaxy the gives off huge amounts of radiation, sometimes having a black hole at it's center. A black hole is a dead star that was big enough to "curl back in itself, like a snake eating it's tail."1 Or picking oneself up and carrying yourself by your bootstraps.One is a single star, one is a galaxy.(1 my words)
What were Steven Hawking's theories?
Stephen Hawking famously posited that the mass of a black hole can indeed decrease, through the mechanism of Hawking radiation. A simplified view of this is that quantum fluctuations near the event horizon, boosted by intense gravity, can generate particle pairs, one of which can escape the vicinity of the black hole and thus carry away energy or mass. In effect this is a thermodynamic interaction with the universe as of black body radiation; the apparent temperature of the black hole being inversely proportional to the its mass. By this mechanism a black hole could 'evaporate', with the rate of evaporation increasing as the mass decreases. This does of course presume that the amount of radiation emitted (Hawking radiation is calculated to be quite weak) is not balanced by the rate at which matter or energy is being absorbed by the black hole.
Do black holes give off radio waves?
Yes, black holes can emit radio waves. These radio waves can come from material accelerating near the black hole before being consumed, or from the interaction of the black hole with its surrounding environment. Studying these radio emissions can provide valuable information about the properties and behavior of black holes.

Why is a black hole a thery not a fact?
there is secondary evidence of a black hole. there is only secondary, because a black hole can be detected by its surrounding, such as the radiation an object gives off as it is being sucked in.
How does pulsar become a black hole?
A pulsar will not become a black hole because they do not implode and that is one of the key features of a star becoming a black hole. a pulsar is highly magnetized and gives off a beam of electromagnetic radiation, when viewed from a distance it will look as though it is flashing.
What does the milky way black hole do?
The black hole at the center of the Milky Way, known as Sagittarius A*, has a mass about four million times that of the Sun. It exerts a strong gravitational pull on surrounding objects and stars, causing them to orbit around it. Gas and dust falling into the black hole give off energy and radiation, making it detectable to telescopes.
What happen to the stuff the black hole sucked in?
For black holes that last more tham a second, It forever becomes part of the black hole. The short lived ones smash everything to energy then bleed off that energy as Hawking radiation.
Why are black holes difficult to locate?
Because they give off absolutely no light and no radiation. The only radiation is X-Rays from the stars being sucked in.
Does iPhone4 give off radiation?
All cell phones give off varying degrees of radiation.
Does kryptonite give off gas or radiation?
Radiation
What matter gives off no electromagnetic radiation?
Nothing escapes from a black hole.
What is the difference between a black hole and a quasar?
A quasar is a galaxy the gives off huge amounts of radiation, sometimes having a black hole at it's center.
