Towards the Unification of Fundamental Interactions

Abstract

Recent observations of distant supernovae show that the universe, contrary to popular belief, is expanding for ever. Similarly, recent experiments at the Superkamiokande facility demonstrate that the Neutrino has a non vanishing mass. Both these discoveries necessitate, at the very least, a re-examination of conventional theories-the Big Bang Theory and the Standard Model. On the other hand, neither has quantum gravity yielded the desired results, nor can String Theory be taken as the last word. We briefly examine this scenario, and in this light consider the recent description of Fermions in terms of the Kerr-Newman metric and the related model of Fluctuational Cosmology. All this is not only consistent with known physics including the latest results alluded to, but also explains hitherto inexplicable empirical facts like the handedness of the Neutrino or the large number relations of Cosmology and so on. It is shown that this scheme leads to a unified description of the fundamental interactions. At the same time, pleasingly, we recover the usual quark picture at the Compton wavelength scale and the Big Bang scenario at the Planck scale.
