- In physics, Kaluza–Klein theory (KK theory) is a classical unified field theory of gravitation and electromagnetism built around the idea of a fifth dimension beyond the common 4D of space and time and considered an important precursor to string theory.
- The conventional graviton is massless, although some models containing massive Kaluza–Klein gravitons exist.
- As an extension, Kaluza–Klein theory and string theory ascribe electromagnetism and the other fundamental forces respectively to the curvature of differently scaled dimensions, which would ultimately imply that all forces are fictitious.
- In string theory, compactification is a generalization of Kaluza–Klein theory.
- That is used in Kaluza-Klein Theory. For the second, the most prominent example arises from the concept of the affine connection that was introduced into the theory of general relativity mainly through the work of Tullio Levi-Civita and Hermann Weyl.
- Further, in a much simpler fashion one may consider a model with only one extra dimension (a type of Kaluza–Klein model) and compactify down to a four-dimensional theory.
- ... gravitational field) in spacetime dimensions higher than four, as described in Kaluza–Klein theory.
- It appears as a radion in Kaluza–Klein theory's compactifications of extra dimensions.
- The Kaluza–Klein theory and subsequent attempts by Einstein to develop unified field theory were never completely successful.
- Klein is credited for inventing the idea, part of Kaluza–Klein theory, that extra dimensions may be physically real but curled up and very small, an idea essential to string theory.
- Theodor Franz Eduard Kaluza ([...]; 9 November 1885 – 19 January 1954) was a German mathematician and physicist known for the Kaluza–Klein theory, involving field equations in five-dimensional space-time.
