Dark Matter and Galactic Collisions, gravitational lensing and the apparatus of wimps under consideration

TL;DR

This paper reviews observational evidence of dark matter, galaxy collisions, gravitational lensing, and discusses WIMPs as potential dark matter candidates, highlighting discrepancies with classical theories and the role of electromagnetic observations.

Contribution

It synthesizes recent astronomical observations and theoretical considerations related to dark matter, galaxy interactions, and gravitational lensing, emphasizing the need for new physics such as WIMPs.

Findings

Galaxy cluster behaviors do not fit existing theories.

Optical spectroscopy measures galaxy rotation curves.

Redshift helps determine cosmic distances.

Abstract

During the last century many observations have been made to peep into the dark matter in the universe and many astonishing behaviors of Galaxy clusters have been found which do not fit to any theories formulated before. However, Optical Spectroscopic observation has been initially used to measure the rotational velocity of the Andromeda Galaxy as a function of distance found in contrast to the Law of Gravitation.Due to the expansion of space, electromagnetic radiation emitted in the distant Universe is redshifted on its path towards us which can be used to determine the distances of astronomical objects.
