September 15

N. Mankoc Borstnik and H. B. Nielsen have written a paper with a (too) long name but a very interesting first page third paragraph: "In an approach by one of us it has long been the wish to obtain the gauge fields from only gravity, so that ”everything” would become gravity. This approach has taken the inspiration from looking for unifying all the internal degrees of freedom, that is the spin and all the charges, into only the spin. This approach is also a kind of the genuine Kaluza-Klein theory, suffering the same problems, with the problem of getting chiral fermions included, unless we can solve them." Since I cannot judge their technical success you have to read the paper if interested.
