Is there any experiment about Kaluza-Klein Theory ? If there is some experiments, What are the results of them ?
There are theory proposals - with these they can evaluate existing data. For example, http://arxiv.org/abs/0710.3677 You can find lots more via Google Scholar; search for "Kaluza-Klein Theory experiments". From what I've seen Kaluza-Klein theories are very unlikely to be true. Hence the move towards more dimensions, string theory, etc.
The analysis says that Kaluza-Klein theories are very unlikely. If you are interested in this type of theory you should learn to read the literature.
Five dimension universe is describe the KK theory and it gives us a solution of KK.I want to ask If we accept five dimension we can say KK is true
