what do you guys know about black holes?

Answer 1

A black hole is made from the remnants of a dead star collapsing under great gravity, become so compact and dense that it warps spacetime enough so even light cannot escape the gravitational pull. This point of no return is called the event horizon. At the center of the black hole is the singularity, a point of infinite pressure and density. The only way for matter to escape the black hole is through Hawking radialtion.

Answer 2

Here we go. According to Stephen Hawking, matter and anti-matter form on the edges of black holes, thus creating things like plants, stars...etc. Also, because of the immense gravity, time in black holes slows down. If someone was to fall into a black hole, they would never cease to be. Black holes are created usually out of dust clouds that condense. The black hole creates a quasar that then creates other stars. The heat of the quasar forces the other dust particles to condense into stars. Once the black hole "eats" its quasar, it goes into a dormant stage. The wind from the dying quasar pushes the other stars back away from the black hole so those stars are too far away for it to feed on which is why it goes into a dormant stage. Every galaxy has a black hole. A galaxy can't form without one. It is also one half of one percent the total size of the galaxy, exactly. Also, the total mass of the galaxy is equal to that which is the total mass of the black hole. A black hole cannot be seen, but you can guess where one is by the presence of a quasar, or the fast movements of the stars around it. The black hole acts like the sun. The sun swings planets around it, as the black hole swings stars around it. There is a theory that if you are on the event horizon, you can see a black hole, and anything that goes into it. Hope that's enough!

Answer 3

A black hole is the result of an enormously massive star with so much gravity it collapsed in on itself. Black holes suck everything in its path into an outragously fast orbit, stedily getting closer to the event horizon, until it is sucked down into the singularity. Some astronomers think that there may be a connection to Black holes a quasars, something called a worm hole. The matter sucked in the black hole would theoretically travel through the worm hole and be ejected by the quasar. But no one can know for sure.

Answer 4

If a black hole could exist it would be an entity with the mass of 2 or 3 suns squeezed into an area about 3 km in diameter.
The surface gravity would be so intense that the surface escape velocity would be greater than the speed of light.
No light could be emitted by it so it would be black.

A black hole is the most powerful, most mysterious phenomenon in the universe. The gravity within a black hole is so intense that not even light, the fastest object we know of, can escape its force. A black hole is so dense that 100 million suns would be compressed to a globe 6 million kilometers in diameter. Our sun is only 1,390,000 kilometers in diameter. It is even theorized that there is a super-massive black hole at the center of every galaxy. These black holes have a center, called a singularity, that supposedly has infinite mass. Therefore a black hole could swallow an entire solar system in seconds if the event horizon could expand that quickly. These destructive and mysterious celestial bodies continue to puzzle astrophysicists and laypersons alike.

Answer 6

a black hole is a small piece of dark matter that is so dence that it has so many nuclei it attracts other atoms towards it (opposites attract), at such a strength that the escape velocity needed to escape it is faster than the speed of light, which is why light cant escape a black hole it is not traveling fast enough. when something enters a black hole it gets so condenced that it actually turns into anti matter with a negativly charged neucleus and positive atoms which flies out almost instantly (likes repel), gravity has the opposite effect on antimatter. if enough antimatter were to clump together because antimatter atracts other antimatter and repels matter it would make the opposite of a blck hole where nothing could go near it because it would be repeled ecxept antimatter which would be attracted. so any matter going near an antimatter black hole would be repeled at the speed of light.

Answer 7

Hawking radiation was also proposed and proved by the great Stephen Hawking. Also, black holes have such an emmense gravity that all of the mass it has is contained in the size of a pin. They also release the matter that they can't hold. If you look at hypethetical pictures of black holes you can see this represented as a white cloud shooting straight out of the black hole itself. I believe I have heard this called "burping".

Answer 8

A black hole is like a bottomless pit that just keeps swollowing eveything that gets too close to it. Space is curved so tightly by it's mass that not even light can escape it. Hawking radiation is just another form of light, it will not get away from a black hole.

Answer 9

It depends on what kind of black holes are you talking about...

Answer 10

All I know is that they are areas of extreme density/mass and/or centers of extreme gravity.

I could be way off, though.
