Are there any additional, unknown, hidden spatial and temporal dimensions in our world? Physicists claim that there are. In 1921, an article by Theodor Kaluza titled "On the Problem of the Unity of Physics" appeared in the journal "Sitzungsberichte der Berliner Akademie" (the article was recommended by A. Einstein). In it, the researcher proposed supplementing the four dimensions of space-time with a fifth, spatial dimension. The introduction of a fifth dimension made it possible to describe all known fundamental forces (gravitational and electromagnetic) through spatial categories. Several years later, the Swedish physicist Oskar Klein expanded this theory, considering other multidimensional variants of the Universe and verifying their compatibility with already known fundamental physical laws. In modern physics, the Kaluza-Klein theory refers to any quantum theory that attempts to unify fundamental interactions in space-time with more than four dimensions. Currently, there are many theories that consider our world to be 5, 6, or even 12-dimensional, with the additional coordinates being either spatial or temporal
