Do blackholes actually exist

Answer 1

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.

Answer 2

Yes. 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.

Answer 3

They 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.

Answer 4

Yes, black holes are real phenomena predicted by Einstein's theory of General Relativity. They are regions in space where gravity is so strong that nothing, not even light, can escape their pull. Astronomers have observed the effects of black holes on nearby objects and have even imaged the silhouette of a black hole at the center of the M87 galaxy.

Answer 5

Yes. It is generally considered that both the theory of black holes is quite sound, and that the observational evidence is quite firm.
