Yes, black holes do, indeed, exist in the universe. We've actually "seen" them, but they can be observed only indirectly. No light can escape them and all nearby matter gets trapped in their gravitational field. Particles which are not far enough away to escape but not close enough to be pulled in are accelerated around the black hole at immense speeds in an accretion disk. The compression and heating of these materials at the event horizon results in the emission of X-ray radiation, which can be detected by orbital X-ray satellites like Chandra. It is also possible to detect a black hole with optical telescopes by spotting what is called gravitational lensing.
The first black hole discovered, Cygnus X-1, was "seen" in the late 1900's. Our galaxy is believed to have several million black holes in it, and they come in various sizes. These include super-massive black holes like Sagittarius A, which is the one at the center of the Milky Way. We'll also see intermediate and stellar black holes, and possibly micro black holes as well. Use the link below to learn more.
There are quite a few, but far beneath the earth.
(did that help or do you think i am really not paying attention to your question)
Yes.
Yes. black holes have been detected in nature.
Which is to say, objects have been detected whose properties are such that no other phenomena could account for them. you can't "see" them for obvious reasons.
I linked some sites that you can go to, they have info and lists and pictures of the known blackholes.

∙ 12y agoYes. Black holes do exist, even though they invisible, but black holes distort light and stars are disappearing as they move.
In fact, in the middle of our galaxy, The Milky Way, there is a black hole, so that mean we are orbiting around the black hole.

∙ 9y agoThey are not actually holes, but they are black, the blackest things in the universe. A black hole is an object, usually left over from a dead star, that has completely crushed itself under the force of gravity. Near a black hole space and time are distorted. Within a certain radius this distortion is so great that nothing can escape. This black area appears as a sphere rather than a hole. The reason they are called black holes is because their gravity is so intense that it sucks in light itself meaning that it reflect off into our telescopes and it just shows up as, black. They are called holes because general relativity suggests that they tear space-time, essentially make a hole.

∙ 7y agoYes. It is generally considered that both the theory of black holes is quite sound, and that the observational evidence is quite firm.

How do you know that blackholes exist?
It is a tricky question because black holes are invisible, but scientists know that they are exist because black holes distort light, so it kind of change the light and also it sucks everything into it, so when scientists see stars starting to disappear, thats mean there is a black hole.
Do blackholes have a diameter Why or Why not?
The "diameter" of a black hole is usually taken as the diameter of the event horizon.
Does blackholes have a pull?
Yes. It's gravity stronger than any force in the universe.
Is a wormhole dangerous?
We don't even know yet whether wormholes actually exist, or even whether they can exist. It seems a little premature to speculate on the exact details.We don't even know yet whether wormholes actually exist, or even whether they can exist.

Did Lucy the cavewoman Actually exist?
Lucy is the name given to the fossilised remains of an early hominid. The remains exist.
Does the moon have blackholes?
No
Are blackholes really white?
No, black holes are actually invisible because it can suck it Light as well, so no light can escape from the black hole.
What is Stephen Hawking currently researching?
Stephen Hawking is currently researching the origins of blackholes and the effects of blackholes on the matter surrounding it.
What can happen if blackholes reach the earth?
If blackholes reach the earth the earth will destroy. Blackhole are to large it can eat star easily.
What are examples of a vacuum?
Blackholes, space, etc
Do fairies actually exist?

Where can you find blackholes?
In space mostly around groups of old stars
Does space have any wormholes or blackholes?
It has both. Hope this helped, WoodWorkingMaster
Which black hole pulls the strongest?
The supermassive blackholes at the center of galaxies.
