  Neutrinos are the second most abundant particle in the universe. Since the
last 50 years, Neutrino physics has been a source of limelight in modern
physics because of the incredible characteristics of this elusive particle.
According to the basic postulates of the Standard Model of particle physics
neutrinos were assumed to be massless, but the results inferred from the
experiments conducted in the past few years in the field of neutrino physics
have concluded that neutrinos have a finite mass. In this paper we have
discussed the various experiments conducted in the past which have tried to set
an experimental limit on the absolute neutrino masses. Further, the future
experiments which are expected to bring these limits to sub eV regime are also
discussed.
