No light comes from a black hole.
There are occasional bursts of X-rays from the accretion disk AROUND the black hole, we believe, caused as dust and gas are accelerated by gravity to nearly the speed of light. That's what we call the "event horizon"; the point at which falling mass is accelerated to lightspeed. Since the math for matter traveling at lightspeed doesn't make any sense, we say "We CAN'T know what happens".
Eventually, many years from now, we'll be able to examine the area around a black hole, but there are none nearby. EVERYTHING we think we know about black holes is based on mathematical theory, and it is highly probable that much of what we think we know is wrong.
Unfortunately, we don't know which parts.

Light can be created by black holes in a few ways. One mechanism is through the accretion disk surrounding the black hole, where matter falling in gets heated up and emits light. Another way is through the jets of high-energy particles that are expelled from near the black hole at close to the speed of light, producing radiation that can be detected in various wavelengths, including visible light.

∙ 15y agoAccording to accepted theory (based on Einstein's General and Special Theories of Relativity) there is no 'exit' - all the mass is slowly collected down to the singularity and from there physics has no idea what happens. Many theories have been put forward, but having no data to go on, it's presently unknowable.

∙ 10y agoBlack holes are thought to be often accompanied by an accretion disk of extremely hot matter which is being drawn into the black hole (and given the rotation, swirling or spiraling in would be an apt description) and emitting radiation particularly in the signature high energy x-ray part of the spectrum. Black holes may also evidence a pair of polar jets emitting vast energy and particles at relativistic speeds - when such jets are aimed at earth these are believed to be markers of the most distant and powerful objects in the universe: quasars, or active galactic nuclei.

This radiation is in the x-ray band, however, not the visible light spectrum. Hawking Radiation is a kind of thermal radiation which reduces the mass of black holes and is the only thing we know of that can escape their pull.

∙ 12y agoNo, that's impossible. No light comes out from the Black Hole, because black hole sucks in light and trap it in there.

How does light calculate in a black hole?
I am not aware of light calculating anything in a black hole.
When was Kids of the Black Hole created?
Kids of the Black Hole was created in 1981.
What makes a black hole black?
Black holes are created when a star runs out of fuel and collapses. That is a nova, A black hole is made when a neutron star goes SuperNova and the energy tears a hole in space, creating a strong gravitational singularity.
When was Songs from the Black Hole created?
Songs from the Black Hole was created in 1994-12.
How does the escape velocity from a black hole compare with the speed of light?
The escape velocity from a black hole is equal to or greater than the speed of light. This means that nothing, not even light, can escape from a black hole once it has crossed its event horizon.
How does light calculate in a black hole?
I am not aware of light calculating anything in a black hole.
What is the brilliant light coming from a black hole?
if there is light surrounding a black hole it is normally from material entering into the event horizon of the black hole.
Can you make light circular?
Only around a black hole. There is a sphere around every black hole where light orbits the black hole.
When was Kids of the Black Hole created?
Kids of the Black Hole was created in 1981.

Black Hole Recordings was created in 1997.
When was Black Hole - comics - created?
Black Hole - comics - was created in 2005.
When was Beyond the Black Hole created?
Beyond the Black Hole was created in 2001.
When was Return to the Black Hole created?
Return to the Black Hole was created in 1997.
If light can be pulled into a black hole that suggests mass What is the weight per square meter?
light has no mass and therefore no weight. Light cannot be "pulled" into a black hole. The escape velocity from a black hole is greater than the speed of light, so no light can escape from a black hole. Spacetime in the vicinity of a black hole is greatly distorted by the hole's gravity, and light may travel along curved geodesics that intersect the black hole. But it is not pulled in.
