Let’s talk about this “fifth dimension” for a second – BGR

• Researchers trying to solve the problem of dark matter have proposed a particle that can reach a fifth unseen dimension.
• The paper is entirely hypothetical, as it attempts to explain a type of matter that no one has ever seen using a particle that has never been identified.
• Proof or rejection of the theory will probably require new technologies that have not yet been invented.

If you’re a fan of science, you’ve probably heard a lot about dark matter in recent years. Dark matter theory is based on the fact that calculations of galaxy motions and other features that we can see in space do not match what we think we know about the laws of the physical world. So to better explain why the universe played the way it did since the Big Bang, there must be a lot of stuff that we either can’t see or we just haven’t identified yet.

But while the idea of ​​dark matter may answer some questions, it raises other issues. If there is so much dark matter in the universe, we should be able to see it at least, but we can’t. In search of an explanation, researchers have begun to form truly incredible theories, including the possibility that a fifth dimension exists and that our inability to interact with that dimension is why we have not yet spotted dark matter. Now, a team of scientists has published a paper that assumes the existence of a particle that could serve as a gateway to that unseen dimension.

Unfortunately, the work has led to some pretty wild titles on the internet. Some media have gone so far as to suggest that scientists have “found” a portal to the fifth dimension, when in reality nothing could be further from the truth. However, the work itself is still extremely interesting.

In the newspaper, which was published in European Journal of Physics C, the researchers wanted to solve some problems related to the abundance of dark matter and particles known as fermions. Fermions are very small – smaller than an atom – and protons and electrons are part of this group. In an attempt to answer the questions they studied, scientists have come up with a new theory of physics that presents not only the four dimensions we know (three dimensions of space and one dimension of time), but a fifth dimension. which a certain type of particle could pass through.

“If this heavy particle existed, it would necessarily connect the visible matter that we know and have studied in detail with the constituents of dark matter, assuming that dark matter is composed of fundamental fermions, which live in the extra dimension,” The scientists said Vice. “This is not a very exaggerated idea, because we know that ordinary matter is made up of fermions and that if there is this extra dimension, they will most likely propagate in it.”

Although it may not be “far away” for scientists, they also make some assumptions here, such as the very existence of the fifth dimension. It is also based on the existing theory of dark matter – that it represents 85% of our universe and exerts a force on objects of our size, but we simply cannot see it – and the existence of this new theoretical particle which, again , no one has ever seen.

There are simply a lot of questions we need to answer before we can even begin to determine the existence of a fifth dimension, and if any of these theoretical blocks are not real, the whole building falls apart. Again, the work is interesting, but no, I did not find the fifth dimension and no, there is no “portal” to actually know about.
