Cosmology
Contents
Cosmology is the study of the Universe and the matter within. The subject has an enormous scope, from the origin of the universe, formation of galaxies, stars and planets to the death of stars and ultimately the fate of the universe. It spans scales of time from an insignificant fraction of a second from when the universe began to time-scales of tens of billions of years. The length-scales are mind-boggling, compared with our everyday experience, creating a truely facinating subject that looks to answer fundamental questions in physics.
