ABSTRACT
Relativity is an essential ingredient for the formulation of the theory of fundamental particles and interactions – the Standard Model of particle physics, for example. On the other hand, the subject of cosmology that helps us understand the evolution of our Universe, its energy budget, the particle density, etc., requires the application of Einstein’s equation of gravity, which in turn based on the theory of relativity. The discussion of dark matter requires the theories of particle physics in order to predict its particle nature. Also, the cosmological ideas are very much essential for the estimation and evolution of dark matter density with the evolution of the Universe. Here we will touch upon essential ingredients of the theory of relativity that will be required for dark matter physics.
