The Role of Neutrinos in the Universe

Abstract

Neutrinos, often referred to as "ghost particles," are elusive and abundant fundamental particles that play crucial roles in various astrophysical phenomena. Despite their weak interaction with matter, neutrinos influence cosmic processes such as stellar evolution, supernova explosions, and the cosmic microwave background radiation. This paper provides a comprehensive overview of the role of neutrinos in the universe, elucidating their significance in understanding fundamental physics and astrophysical phenomena.
