Abstract

A novel proposal is made to account for the dark matter component of the Universe. Ultralight dark matter with mass $\leq {\cal{O}}(10^{-22})~eV$ is one of the strong candidates for the missing mass which aids the formation of galaxies as well as holding them together. They are also known as fuzzy dark matter(FDM) which will come under Cold Dark matter. The question is what is this particle and its implications. How do we experimentally see it is an outstanding question. We propose to answer some of these questions with some evidences and the estimates.
