On Direct Detection of Cosmic Neutrino Background & Cosmic Singularity

Abstract

According to standard cosmology, neutrinos should be the most abundant particles in the Universe after CMB photons. The CMB neutrino is the oldest relic, present since BBN era. However, in the past 5 decades or so, attempts to directly detect Cosmic Neutrino Background have never been succeeded. Taking into considerations of two recent developments, I argue that the direct detection of Cosmic Neutrino Background is impossible because there is no such thing as Cosmic Singularity.
