This book deals with questions concerning the origin, structure and nature of the universe in sixteen chapters. The study of the Universe has a long history involving science, philosophy, esotericism, and religion, but the name cosmology was first used only in the later 18th century. Philosophy began with wonder at the reality that was obvious to human eyes, yet its origin, makeup and growing up during the times gone by has surprised most of the thinkers. It is different from the science as well as myth. The goal of all the three is to explain the reality, but the methods and course that they hold on to are quite different. There is a slow development from myth to philosophy and then to science. Myths are not existentially true and meaningful; philosophy tries to be factually true and meaningful by rational investigation. Science attempts to be factually true and does not directly influence the existential meaning. Myths provide us with intuitive and existential meaning. Philosophy gives us rational meaning. Science shows us empirical facts. Hope this sixteen chapter as a whole will enlighten the readers on the subject of cosmic philosophy of science.
