What Are White Holes?
Our outer space is full of big puzzles that humans have not yet discovered, and perhaps one of the strangest and most interesting things in space are White Holes. But what do these holes mean when they really do exist?
Before talking about white holes, we must know what are black holes? Of course, black holes form when massive stars reach the end of their lives, collapsing on themselves, leaving them with a density that is extremely high in intensity and gravitational enough that even light cannot escape.
It swallows everything close to it from planets and space astray, perhaps even the spaceships that lost its way in the past, and the question that scientists are trying to answer remains, what is the fate of what crosses the black hole and are there parallel worlds?
White holes are a purely mathematical concept based on the subtraction of mass and matter from a collapsed star, so that the residual, mass less portion is the white hole.
By this definition, physicists attempt to explain the fate of planets or any material swallowed up in a black hole.
In other words, the white hole is the opposite component of the black hole, that is, while the black hole attracts everything – even light – towards it,
The white hole pushes everything away from it, and since the laws of general relativity do not define a specific direction of space and since it has been proven The presence of a black hole, in the same way white holes can be present.
How white holes are formed
The theory says that black holes that in the past attracted and swallowed everything from its surroundings, and under certain conditions would turn into white holes that would repel all that. Hence white holes came as a possible answer to the question of general relativity about the possibility of losing space data through black holes.
The theory suggests that this transformation takes place immediately after the formation of a black hole – but since gravity extends time, it would seem to observers from the outside (Earth, for example) that it took millions of years-.
If the owners of this hypothesis were right, then the black holes that had formed millions of years ago would now be ready to turn into white holes, which we will see from Earth as high-energy radiation in space.
But the question lies behind the fact that these holes exist, but if they exist, no one will ever be able to see them, as the radiation from the hole will have to cross the event horizon that is the boundary between the hole and the surrounding environment.
Since the event horizon is outside of space-time, the ray will take too long to reach us and we will not see it. Nevertheless, many scientists believe that white holes are present and even consider them equivalent to the big bang.
However, the theory of the formation of white holes or even the big bang is the opposite of the second law of thermodynamics, which states that entropy (or perturbation) must increase over time. It assumes that by decreasing entropy we can reverse time and thus obtain a white hole, and that The Big Bang occurs as soon as entropy and time resume their normal direction.
