Ka·lu·za-Klein theory

 (kə-lo͞o′zə-klīn′)
n.
1. A theory that seeks to unify the force of electromagnetism as described by Maxwell's equations and the force of gravity as described by general relativity, explaining each as manifestations of a single fundamental force and introducing a hypothetical fifth dimension.
2. Any of various physical theories introducing dimensions additional to the four dimensions of space and time.

[After Theodor Kaluza (1885-1954), German mathematician and physicist, and Oskar Klein (1894-1977), Swedish physicist.]

Therefore, in order to study this model, we consider the proposed gravity function F(T, [THETA]) in a five-dimensional space-time compressed by the Kaluza-Klein theory [11,14]:

For the FLRW metric, we first derive a modified Friedmann equation from the five-dimensional Fully covariant Kaluza-Klein theory with a scalar field (Zhang, ApJL 2006, 636, L61 and references therein), which unifies the four-dimensional Einsteinian general theory of relativity and Maxwellian electromagnetic theory.
Hyperspace theory is also referred to as Kaluza-Klein theory and supergravity.
It wasn't until the early 1980s that physics resurrected the 60-year-old Kaluza-Klein theory. Actually, some clues were incipient in the late 1960s when the five-dimensional Kaluza-Klein model exhibited a certain freedom to impose symmetry on hyperspace, where Maxwell's field appeared out of Riemann metric space almost as if by magic.
Our model is, in fact, a generalization of Kaluza-Klein theory to 11 + 3-dimensional space-time.
A 5D gravity is a Kaluza-Klein theory that unifies the 4D Einsteinian general relativity (GR) and Maxwellian electromagnetism (EM).
Recently, the author has developed a new mechanism for supernova explosion caused by gravitational field shielding [18], in accordance with his five-dimensional (5D) fully covariant Kaluza-Klein theory with a scalar field [8,19,20].

This was first conjectured in Kaluza-Klein theory [19].
On the other hand, Kaluza-Klein theory geometrically unified the four-dimensional Einsteinian general theory of relativity and Maxwellian electromagnetic theory into a five-dimensional unification theory ([7-9] for the original studies, [10] for an extensive review, and [11, 12] for the field solutions).
