Many of you have heard of black holes, which are objects whose gravity is so immense that even light cannot escape them. But have you heard of the exact opposite of those objects? They are theoretical objects known as white holes, and they are very bizarre. Let’s find out about them in this article.
What Are White Holes?
Firstly, we have to discuss what a white hole is. They are objects that keep anything far away. In other words, they don’t allow objects to cross the event horizon from the outside. In other words, they kick things out of the way if objects get close. They are even more peculiar than black holes since we don’t know how they can form, and these objects might not exist at all. Keep in mind that they are just proposed by science theories, and they might not be actual objects.
They are dubbed “white holes” because they release whatever they receive, including light. Therefore, it could be very bright, and we can probably detect them using current technology if these objects are currently in the Universe.
Evidence of White Holes
A science hypothesis as large as this must have some evidence, right? White holes might solve a fundamental contradiction (the black hole information paradox) about the Universe.
The laws of quantum mechanics state that quantum information cannot be destroyed under any circumstances. However, as far as we know, black holes seem to be disobeying this law. The Hawking radiation it emits seems not to carry the information that was swallowed into the black hole. This creates a contradiction, and this could change our understanding of the Universe significantly and for good.
There are numerous possible solutions to this paradox, and one of those is white holes.
There is other evidence for the existence of a white hole, which includes a gamma-ray burst discovered in 2006. It is so weird that this might be light from the exact opposite thing to black holes. Moreover, the big bang itself, which created the Universe, might be formed from a white hole. The entire cosmos started with a singularity and suddenly expanded quickly. It looks eerily similar to a white hole in our theory.
In this article, we talked about white holes, which are objects that we cannot reach by any means. Even though this article might provide some information about these weird objects, we have to learn more. Therefore, please read the articles in the references below.
