This book firstly inquires why the basic questions pertaining to the origin of our universe have not been answered so far. Then it argues that there are serious drawbacks in the proposals of scientific cosmology, mainly pluralism and underlying scientific realism. So the search for the most elementary form of matter is elusive. There are controversies pertaining to the mathematical models representing standard model particles, quantum gravity, strings, etc. The philosophical notion of system is a new idea introduced here, represented by the X-Y model of coordinate geometry. Accordingly, the physical world is a matter-energy system, which is the physical reduction of matter-consciousness system of inanimate world. Things exist by the union of opposites. The idea of consciousness in nature removes the conundrum of intelligent designer or God. The book presents the final solution of the cosmological puzzles related to space, time, Big Bang, and multiverse. The dilemmas of great physicists like Albert Einstein and Stephen Hawking are resolved. Moreover, through system philosophy, this book inventively reconciles the conflicts in the doctrines of philosophy of science. Written in a pedagogic style, explaining all basic concepts, it would serve as text as well as reference for all inquisitive readers.
