A black hole has two main components: the singularity and the event horizon. The singularity is the point at which the black hole's mass is concentrated. The nature of the singularity is not known as the laws of physics are we currently understand them break down under these extreme conditions. The event horizon is a spherical region around the black hole from which nothing can escape once it crosses inside, not even light.
If a black hole is feeding the in-falling matter may form a swirling accretion disk. As the matter approaches that black hole it gets forced into a small space and becomes extremely hot, emitting powerful x-rays. Not all of the matter can fit in. What doesn't fit gets ejected in two beams of subatomic particles moving at nearly the speed of light.

∙ 13y agoSometimes - no-one knows why - stars collapse in on themselves. This increases their gravity (a force that pulls everything inwards). Nothing escapes - not even light. These very dense bodies are called black holes. :)

∙ 10y agoAnswer: The only property that scientists can agree on is that a black hole is a phenomenon whereby gravity has become so intense, that even light itself is bent back around and cannot escape.
Beyond that, different groups of scientists have speculated about what may occur. Some theories include that black holes are rips in the fabric of our universe, leading either to another time or another universe altogether, or that quasars are where the matter and energy from black holes are returned to our universe.
Since just about every galaxy we've found has a supermassive black hole at its center -- including our own Milky Way -- another conjecture is that such oversized black holes are somehow required for galaxy formation, in some as-yet poorly understood way.
My personal favorite saying about black holes, however, is that black holes are where God is dividing by zero.
Answer: The only properties that can distinguish one black hole from another are its mass, its rotational momentum, and its electric charge. The electric charge is expected to equal to zero. Even magnetic fields disappear in black holes.

How did Karl schwarzschild discover cosmic black holes?
He did not discover them. He did some calculations that predicted the possibility of the existence of black holes.
Are there galaxies with no supermassive black holes?
Yes. Some galaxies, particularly irregular galaxies, appear to lack supermassive black holes.
Can black holes dies?
Black holes do not die but they can evaporate.
Why are black holes round?
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
What would happen if the milky way black hole became active?
It would emit a lot of radiation. Some distant black holes (or more accurately, the area around the black holes) emit more radiation than an entire galaxy. Such black holes are known as quasars.
Do mini black holes exist?
yes. some black holes are predicted to be the size of an electron.
Is the sun bigger then a black hole?
Black holes can be many different sizes. Therefore, there are some black holes that are bigger than the sun, and there are some that are smaller than the sun.
How did Dr. Stephen Hawking discover black holes?
He did not. He made some theoretical discoveries about how black holes would probably behave; but the concept of black holes was discovered by others before him.

What are some geological features of the moon?
holes in the moon and foot prints and craters
What happens to a star when it becomes a super giant?
Some do, some become "bright giants" instead.
What were black holes before they turned into black holes?
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
Is the universe made of black holes?
No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.

Have black holes affected people today?
Not directly. Black holes have only affected people insomuch as they attract. people's attention and that some take time to study them.
