5th Dimension Reality

Wikipedia has an introductory article on Kaluza Klein theory that may be of interest:

One thing to be aware of is that this is a very deep theory and there may not be anyone here who can properly or adequately comment on it let alone answer your questions.

What is your interest in KK theory and what level of schooling do you have so far?

 

Actually in KK its curled up in a circle and this enforces the so called cylinder assumption which is the real basis of why KK works:

The cylinder assumption is the geometry of a circle ie U(1) symmetry which is in fact the basis EM - so in a sense its EM in EM out. Once this was understood it lost much of its appeal and is pretty backwater these days.

Regarding locality it's quantisation would be a QFT and locality in that depends on the so called Cluster Decomposition property:

Thanks Bhoppa, it seems now we can close the thread.
