https://en.m.wikipedia.org/wiki/Kaluza–Klein_theoryIt was originally formulated as a way to geometrically unify electromagnetism with gravity. Solving the Einstein field equations in 4+1 dimensions (where one of the spatial dimensions is periodic) gives the 10 original EFEs for 3+1 dimensions along with Maxwell’s equations. There’s also an extra scalar equation that predicts the existence of a hypothetical particle called the dilaton which has never been observed. KK theory has fallen somewhat out of favor because it only treats fermions in an ad hoc manner, but it is an important jumping off point for many modern beyond-Standard-Model theories that incorporate dimensional compactification.
