The standard model of cosmology, i.e., the big bang theory, along with cosmic microwave background (CMB), also predicts the existence of a cosmic neutrino background (C
B). This CB is comprised of ultra low energy neutrinos. Their detection can provide us the information about the Universe at a stage earlier than the CMB can provide. In this short review, we present basic theoretical properties and constraints on CB and subsequently present a quick review of the experimental proposals for its detection. In addition to this, we also discuss the effect of generalized neutrino interactions on the CB detection via the neutrino capture process at PTOLEMY.
