The dark matter is considered to be one of the most fascinating mysteries of the current astrophysics. It neither emits, absorbs, or reflects light, but its gravitational effect is fundamental to the description of the formation of the galaxy and its movement. It is observed that only visible matter can not explain the rotational speed of galaxies or the stability of the formations of the universe on a large scale.
The presence of the dark matter was highly advocated through the studies by Vera Rubin who had studied the galaxy rotation curves in the 20 th century. She found that the stars at the outer centers of the spiral galaxies travel at the same pace as those at the center, which did not match with expectations made according to the observable mass only. This aberration implied that there was some undetected mass which acted as an added gravitational force.
Additional support is provided by the phenomenon of gravitational lensing, which is the prediction of the general relativity. The giant clusters of galaxies bend the light of distant objects behind the clusters. The extent of bending shows the presence of more mass than can be discerned by observation. The dark matter is accredited with this invisible aspect.
Recent theories suggest that the dark matter is a massive cosmic web, which plays the role of a structure around which the galaxies are built. Largely, the very large-scale distribution of matter in the universe would look very different in its absence. Although it is important, the exact composition of the dark matter is not known. Theoretical particle model Theory
Learning about the dark matter will help to improve the models of the galaxy and how it appears soon after the Big Bang. It has a gravitational contribution to the galaxy clusters as well as the cosmic background fluctuations.
