KaluzaKleinRäumen

KaluzaKleinRäumen, often referred to as Kaluza-Klein spaces, are a concept in theoretical physics that extends the familiar dimensions of spacetime by introducing additional, compactified spatial dimensions. The idea originated with Theodor Kaluza in 1919, who proposed a fifth dimension to unify gravity and electromagnetism within a single geometric framework. Later, Oskar Klein refined this idea by suggesting that these extra dimensions could be curled up into a very small size, making them undetectable at everyday energy scales.

The core principle behind Kaluza-Klein theory is that by increasing the number of spatial dimensions, new physical phenomena and forces can emerge. In the original Kaluza-Kaluza-Klein model, the curvature of the fifth dimension was interpreted as the electromagnetic field. This provided an elegant mathematical unification of general relativity and Maxwell's equations.

Modern extensions of Kaluza-Klein theory explore scenarios with many more extra dimensions, often called "large extra dimensions" or "brane worlds." In these models, our observable universe is thought to be confined to a "brane" embedded in a higher-dimensional space, known as the "bulk." Gravity, unlike other forces, is hypothesized to be able to propagate through the bulk, which could explain why it appears so much weaker than the other fundamental forces. Research in this area aims to address fundamental questions in physics, such as the hierarchy problem and the nature of dark matter and dark energy.
