Isnt there something that can escape a black hole?

Question

A black hole absorbs everything including light itself. Are radio waves/ radiation affected by the black hole?

Answer 1

Stephen Hawking theorized (and proved mathematically) that mass leaves a black hole in the form of Hawking radiation (they named it after him). At the event horizon of a black hole, matter is created in the form of vaccuum energy, just like everywhere else in space. But at the event horizon some of the vaccuum energy becomes permanently separated from their anti-particle counterpart before they can cancel each other out, releasing energy into space. The smaller a black hole is, the greater the release of Hawking radiation because the event horizon becomes sharper in curve (gravitationally speaking).

Answer 2

Hummm....I think NO. All properties discussed are based on the physics we know on the earth. It may not be applicable while doing the real experiment. How does the black hole look like? A cylinder with 2 openings, top and bottom? What could be the depth of it? Even if we want to experiment, say by firing very high pulses of a Laser Beam in the black hole, where is the other opening where we can measure if something is coming out? All assumptions....

Answer 3

black holes are not so black. They have an entropy, which can only increase, and thus a temperature: the black holes emit particles and thermal " radiation ", with a temperature which depends only on their mass: the black hole is the more " hot " that it is not very massive. These particles are emitted in a zone right outside the horizon of the black hole (limit inside which nothing can escape). It is a quantum effect, based on the spontaneous creation of pairs of particle-antiparticles in the energy fluctuations of the vacuum

In the intermediate mass range, it could exist very hot black holes, still evaporating today. At the time of the final phases of evaporation, the mass of the black hole becomes infinitely small, and thus its temperature tends towards infinity. The black hole disappears in a fantastic explosion. The last phases of the evaporation of the black hole remained to be elucidated.

Answer 4

If a very very very advance life form on a planet invented a machine that can go 2 time the speed of light then yes something can escape a black hole otherwise no.

Answer 5

No, nothing can escape the black hole, not even light itself; (radio waves are a frequency of light that we cannot see). The gravity in space is set in a plane (like a grid). Planets, stars and other objects make a small indenation in this grid, so they have a pull on things. A black hole, however, makes something like a whirlpool does in water- a steep vortex; this gives it enormous power.

Answer 6

Yes, they are. All wavelength energy is drawn into the black hole if it gets close enough. Whether it would "realize" that it is in a black hole is another matter (would make a good question to the physics geeks).

Answer 7

in an article about slingshotting from black holes, they were talking about X-rays being able to shoot through a black hole, and not seem to be affected.

i have a hard time believing that, because i don't understand how such a thing was even tested prior to the article i read.

that said, hawking has a theory about radiation emanating from the black hole, but from what i understand on what is written, that emanation is not from the black hole, but from just inside the event horizon

Answer 8

If a black hole could exist nothing could escape it's clutches Hawking radiation not withstanding
It would not discriminate among anything the universe could throw at it.
It would live for eternity in a finite universe.

Answer 9

there's a singularity on the middle of the black hollow. The singularity includes all of a celebrity's mass, in spite of is left after the supernova, at a quantity of 0 length. What precisely that does to the fabric of area-time remains unknown. it would quite be waiting to tear a hollow interior the gap-time. via ways, it is the density of the black hollow, no longer its super mass, that reasons such super gravitational appeal. you should turn Earth right into a black hollow in case you may compress all of it the way down to a sufficiently small quantity.

Answer 10

Yes, anything that has any kind of magnetic or gravitational properties is food for a black hole. Haven`t heard of anything that will not be trapped.
