Wormhole: How does this mysterious phenomenon work?

In 1915, Albert Einstein revolutionized the field of physics by proposing the Theory of Relativity, a study for which he ended up eternalizing his name. To better explain what the presented phenomenon consisted of, he used wormholes as a way to substantiate his thesis, something that changed the perception of space and time at the time.

Even today, after more than a century of discussion, many people still have doubts about what wormholes are and how they work. Keep reading to resolve all the questions and understand at once what Einstein meant when he first used the picture of the phenomenon.

Black hole: what it is and how it works

Initially, it was believed that wormholes did not really exist, serving only to justify theoretical aspects, but Einstein did not conform to the thought and sought to rectify it. That was how, together with Nathan Rosen, a great name in physics, the article was born that aimed to explain the way the black hole works from its counterpoint, the white hole.

The first is known to suck everything that appears in front of you, including bodies, matter and even light. With this thought, the white hole would be the opposite, always working on the basis of expelling everything, leading to the thought that both phenomena are connected: while the black hole absorbs, the white hole is responsible for expelling.

This thought was called the Einstein-Rosen Bridge, but it ended up being popularized by the term “wormhole”, first used in 1957 thanks to the physicist John Wheeler.

Do black holes exist?

In practice, it is very likely not, even with the arguments put forward by Einstein. However, in theory, they are highly accepted, as stated by astronomer Andrew Pontzen. This is because, for wormholes to exist in our reality, there must be dark matter, which is thought to be the only way to keep a black hole open and stable, in a way.

In other words, the scenario in which the phenomenon is real depends on many factors, making it increasingly unlikely. However, it is worth noting that this area of ​​physics is studied frequently, and at any time a new discovery can be made, making the existence of wormholes possible beyond theory.

Wormhole in fiction

In 1985, Carl Sagan, a renowned astrophysicist, wrote Contact, book that shows the interaction between human beings and extraterrestrials, whose encounter would be provided by a trip through the wormhole. As he eventually discovered, this tour would not be possible, as human organs would be pulled in different directions due to gravity, making them almost spaghetti after a process of stretching and compressing.

To resolve this clash, he enlisted the help of Kip Thorne, a great expert on relativity who managed to find a logical solution that Sagan could show in his work.

In addition to the new idea appearing in Contact, both in the book and in the 1997 film adaptation, it was published in a physics magazine that helped scientists think about the wormhole phenomenon from a new perspective.

But there are also works that do not care so much for logical security, opting to defy the laws of physics. Good examples to illustrate this situation are the films in the trilogy Back to the future or the series Dark, from Netflix, who deal with the idea of ​​time travel through wormholes, something that is seen as impossible, but that provides entertainment for the public.
