II am interested in Physical cosmology, as a branch of astronomy, is the study of the largest-scale structures and dynamics of our universe and is concerned with fundamental questions about its formation and evolution. Cosmology involves itself with studying the motions of the celestial bodies and the first cause. For most of human history, it has been a branch of metaphysics. Cosmology as a science originates with the Copernican principle, which implies that celestial bodies obey same physical laws to those on earth, and Newtonian mechanics, which first allowed us to understand those motions. This is now called celestial mechanics. Physical cosmology, as it is now understood, began with the twentieth century development of Albert Einstein’s general theory of relativity and better astronomical observations of extremely distant objects.
I am interested to learn about the origins of the universe and the Big Bang as the leading cosmological model, which most cosmologists now accept as the basis for their theories and observations and (galaxies, clusters and superclusters), the very earliest distinct objects to form (quasars) and the very early universe.
