This monograph is based on the authors own research work and his research based lectures and seminars and public lectures and is meant to initiate the reader into research in Loop Quantum Gravity (LQG). The book contains research on more theoretical physical lines and does not boast of mathematical rigor unlike conventional LQG. It urges the reader towards precise and physically viable and verifiable thinking. The duality of time in physical theory both quantum mechanical and quantum gravitational is the crowning achieving of this work. A quantum Yang-Mills gauge theory of gravity is...
