Black holes are invisible but the matter falling in makes friction and heats up which glows and gives of heat,x rays,etc.
Most black holes look like galaxies, you know, the usual swirl with the strange black dot in the middle. Some black holes look like a simple black dot, floating in space.

∙ 11y agoA Black Hole model is considered more or less like that for stellar mass, with the exception that its mass density is such that its force of gravitational acceleration toward its mass is faster than the speed of light. This immense gravitational attraction not only pulls in other mass objects, but condenses and converts the attracted mass in energy. To describe this condition, I would refer to the state of the universe immediately after the Big Bang event; i.e. this condition provided for a hot dense state of plasma. Consequently, there is no real mass within a black hole; rather all attracted mass is converted to energy. If fact our best evidence ever was provided with the observations of the three-telescope interferometry. The astrophysicists described their findings as a ring of hot dust that marks the transition from a more-distant mixture of gas and dust in a toroidal (doughnut-shaped) structure, to a gaseous disk closer to the black hole. The dusty part, he said, is interesting because it dominates the infrared emission of active galactic nuclei and can be easily observed. Once pulled in beyond a Black Hole's event horizon, the only escape is in the form of relativistic jets emitted along the poles, which carry away much of the energy. Among Stephen William Hawking's significant scientific works have been a collaboration with Roger Penrose on gravitational singularities theorems in the framework of general relativity, and the theoretical prediction that black holes emit radiation, often called Hawking radiation.

What are the two parts of the black hole?
The two parts of a black hole are the event horizon and the singularity. The event horizon is the "surface" of the black hole, and is imaginary. The event horizon's appearance is caused by the bending of light. The singularity is a point of space where everything that gets sucked in is crushed to about the size of an atom.
What does a black hole do with what it suck in?
The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
Can any black hole turn into a neutron star?
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
Sentence for black hole?
A black hole is a type of star with excessive gravity. Here are some sentences.The star was sucked into the black hole close by.A black hole will even absorb light.The scientist is studying a black hole.
How big is Neptunes Black hole?
Neptune does not have a black hole

A collapsed star from which light cannot escape?
The collapses star gets squeezed by collapses gas and turns into a black hole.
What is the difference between a Scchwarzschild and a Kerr black hole?
A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole. Since the latter is more complicated to describe, it was developed much later.A Schwarzschild black hole is a non-rotating black hole. The Kerr black hole is a rotating black hole.

What does the black hole do to the star?
A black hole originated as a star, that is, the star converted to a black hole.
What does a black hole do with what it suck in?
The material sucked in to a black hole becomes part of the black hole - that is, a black hole crushes matter to an nearly no size, at all.
Where will you go in a black hole it?
If you fall into a black hole, you'll go into the black hole and nowhere else.
What is the environment in a black hole?
probs black hole
Is the super massive black hole the largest black hole?
Black hole is a location in space that possesses so much gravity, nothing can escape from its pull. Yes, Super massive black hole is the largest black hole.
Can any black hole turn into a neutron star?
No. A black hole will remain a black hole. A neutron star is a remnant of a star not massive enough to become a black hole.
Can you make a black hole inside a black hole?
We know nothing about the conditions within a black hole, but it seems unlikely that a black hole could exist within a black hole, or even if this concept would have any meaning at all.
Is an Intermediate-mass black hole a type of black hole?
Yes. Intermediate-mass blackhole is a medium size black hole. Scientists have found stellar black holes and supermassive black holes but there is no prove that Intermediate-mass black type of black holes exist. My opinion is that they do exist because when a black hole is becoming a black hole supermassiveblack hole it will need to go though this stage of intermediate-mass black hole.
