When matter falls into or comes closer than the event horizon of a black hole, it becomes isolated from the rest of space-time. It can never leave that region. For all practical purposes the matter has disappeared from the universe.Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius A. It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths.For example, black holes have helped us test Einstein's theory of general relativity, which describes how mass, space, and time are related to one another. Scientists think they can tell us much more about these and other essential rules of the universe.
Are white holes real : White holes are the opposite of black holes, in that they spit out light and matter, rather than trapping it. So far, white holes are purely hypothetical objects, but astronomers are contemplating how they could form in reality.
Are black holes fake
Black holes seem to be the stuff of science fiction (and, in fact, have starred in many sci-fi books and movies), so it's not uncommon for people to wonder, are black holes real As it turns out, the answer is yes, though for a long time most scientists were convinced that black holes were purely theoretical objects.

Since this black hole already weighs a few million times the mass of the Sun, there will only be small increases in its mass if it swallows a few more Sun-like stars. There is no danger of the Earth (located 26,000 light years away from the Milky Way's black hole) being pulled in. A Q-star, also known as a grey hole, is a hypothetical type of a compact, heavy neutron star with an exotic state of matter. Such a star can be smaller than the progenitor star's Schwarzschild radius and have a gravitational pull so strong that some light, but not all photons, can escape.
Is red hole real
Researchers have discovered an extremely red supermassive black hole thanks to the help of some gravitational lensing. Researchers used the James Webb Space Telescope to detect an extremely red, gravitationally lensed supermassive black-hole in the early Universe.Stellar black holes are very cold: they have a temperature of nearly absolute zero – which is zero Kelvin, or −273.15 degrees Celsius. Supermassive black holes are even colder. But a black hole's event horizon is incredibly hot. The gas being pulled rapidly into a black hole can reach millions of degrees.This gas gets so hot that it normally emits either X-rays, ultra-violet light or blue light. Thus most black holes that we could see with the human eye would appear bright blue-white. A few appear yellow, but this isn't their true colour: the really are blue, but are obscured by interstellar dust.

What is 1 hour in a black hole : Expert-Verified Answer. For a black hole observer, one hour is equivalent to 100,000,000 years on Earth. In contrast to time distant from a black hole, time moves more slowly as you approach closer to one.
What is a pink hole in space : At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. It turns out that this is only true for a few of them: most have the wrong colours to be expained by this.
Do green holes exist
Green Holes are special types of star that are so rare! Green holes form if black holes don't lose mass or only lose a ton of mass in a billion years! That happens if the star is super massive, like a hypergiant or a metagiant. There is no evidence that these things exist, or even that they are possible. It is pure unsupported speculation at this point, so we are tying hard to find more prosaic explanations of what is going on. If this fails, we may be forced to use one of these bizarre theories.We are in absolutely no danger from black holes. They're a bit like tigers – it's a bad idea to stick your head in their mouth, but you're probably not going to meet one on your way to the shops. Unlike tigers, black holes don't hunt. They're not roaming around space eating stars and planets.
