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.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.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.
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.
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.
Are we 100% sure black holes exist : There is consensus that supermassive black holes exist in the centres of most galaxies. The presence of a black hole can be inferred through its interaction with other matter and with electromagnetic radiation such as visible light.
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.

Do wormholes exist
Einstein's theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.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.Cosmologists aren't sure if the universe is infinitely big or just extremely large. To measure the universe, astronomers instead look at its curvature. The geometric curve on large scales of the universe tells us about its overall shape. If the universe is perfectly geometrically flat, then it can be infinite. Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system. But scientists have observed black holes ripping stars apart, a process that releases a tremendous amount of energy.
Does time exist in a black hole : From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole. Inside a black hole is where the real mystery lies. According to Einstein's theory, time and space, in a way, trade places inside the hole.
Does space ever end : In either case, you could never get to the end of the universe or space. Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.
Is space hot or cold
The sun is a bolus of gas and fire measuring around 27 million degrees Fahrenheit at its core and 10,000 degrees at its surface. Meanwhile, the cosmic background temperature—the temperature of space once you get far enough away to escape Earth's balmy atmosphere—hovers at -455 F. No material that falls inside a black hole could survive intact. Unfortunately, because nothing can escape a black hole's event horizon — not even information — we'll never know for certain what happens when matter falls past the point of no return.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.
How much is 1 minute in black holes : “If you were to stand just outside the event horizon of Sagittarius A*, and you stood there for one minute, 700 years would pass because time passes so much slower in the gravitational field there than it does on Earth.” Some have suggested that black holes could be used for time travel.
