Narlikar, J. V.2012-03-062012-03-061962-06-05http://hdl.handle.net/11007/773Hogarth's approach to the time-symmetric electrodynamics of Wheeler & Feynman is extended to apply to the neutrinos. It is shown that in some cosmological models neutrinos travelling both into the past and the future exist whereas in others only those going into the the future can exist. The Einstein-de Sitter and the steady-state models are the respective examples of the two cases. An interesting way of testing the various cosmologies by means of neutrino emitters and receivers is suggested.enNeutrinosCosmologyElectrodynamicsCosmological modelArticle
