Hidden Variables?

Many years ago David Bohm pursued an important idea. Is Quantum Mechanics complete? John von Neuman had "proven" that hidden variable theories were impossible. What Bohm did was to construct one of those "impossible" theories.

Now Y. Jack Ng tells us:

"Infinite statistics can be thought of as corresponding to the statistics of identical particles with an infinite number of internal degrees of freedom, which is equivalent to the statistics of nonidentical particles since they are distinguishable by their internal states."

This rings another bell, recently Gia Dvali proposed a solution to the strong CP problem with a big number of "hidden" particles. You can read his paper here
