Abstract

Dark matter is a kind of matter that we cannot see directly. Scientists have detected dark matter by analyzing the relationship between the curvature of light, mass, gravity, and velocity of the visible stars in galaxies. For example, the higher speed of the side stars of a galaxy implies more mass in the galaxy. However, they cannot describe it clearly. Here we show that faster conversion of the spectrum of dark matter to the spectrum of the Cosmic Microwave Background (CMB) is the reason why they are hidden. Hence, an emitter could be visible to nearby observers, while more distant observers detect it as a dark matter.
