In general relativity, a white hole is a hypothetical region of spacetime and singularity that cannot be entered from the outside, although energy-matter, light and information can escape from it. In this sense, it is the reverse of a black hole, from which energy-matter, light and information cannot escape.Scientists like Roger Penrose theorize that a white hole is like an exit for a black hole in another universe. So material would fall into a black hole in one universe and would get ejected into another universe via a white hole.So according to laws of physics. It should not exist in a universe. But I have an idea like how can it exist in our universe. So the idea is that let's say we have a star made up of matter.
What is a grey hole : 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.
Are we in a white hole
Even though we don't observe any evidence for white holes within our Universe, the fact that we had a Big Bang and the fact that we have black holes within our Universe is quite consistent with the idea that there's a “white hole” on the other end of every black hole that's ever been created.
What if a black hole meets a white hole : Answer and Explanation:
A white hole is a region which nothing may ever enter, only escape from. Thus, if the two were to collide, the white hole would enter the black hole, becoming part of it from an outside perspective. Once the white hole has entered the black hole a type of layered structure would exist.
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.
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.
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.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.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.
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.
Do white holes exist : 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.
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.
We can't smell space directly, because our noses don't work in a vacuum. But astronauts aboard the ISS have reported that they notice a metallic aroma – like the smell of welding fumes – on the surface of their spacesuits once the airlock has re-pressurised.Other astronauts have described it in similar yet varying ways: "burning metal," "a distinct odor of ozone, an acrid smell," "walnuts and brake pads," "gunpowder" and even "burnt almond cookie." Much like all wine connoisseurs smell something a bit different in the bottle, astronaut reports differ slightly in their " …
Does space have an end : One thing's for sure: the Universe does not have an edge. There's no physical boundary – no wall, no border, no fence around the edges of the cosmos. This doesn't necessarily mean that the Universe is infinitely large though.
