What exactly is physical reality? In elegant and accessible prose, theoretical physicist Balungi Francis leads us on a wondrous journey from space time singularities to Quantum Black Holes without information loss, from the Bekenstein-Hawking Area entropy law to his famous Volume entropy law of Black holes, from Modified Newtonian Dynamics, Dark Matter to Planck mass particles, from White Dwarfs to Black Holes and from General Relativity to his own work in Quantum Gravity. As he shows us how the idea of reality has evolved over time, Balungi offers deeper explanations of the theories he introduced so concisely in Quantum Gravity in a Nutshell1. Balungi invites us to imagine a marvelous world where space breaks up into tiny grains, singularities disappears, information loss in Black holes resolved, time disappears at the smallest scales, and black holes are waiting to explode.
This wonderful and exciting book is optimal for physics graduate students and researchers. The physical explanations are exceedingly well written and integrated with formulas. Quantum Gravity is the next big thing and this book will help the reader understand and use the theory.
