The book, based on the author's Ph.D. thesis, delves into the intricate concept of time in quantum gravity and its profound implications for understanding the physics of the early Universe. It presents a novel and comprehensive relational formulation of quantum gravity, specifically tailored for quantum mechanics models with diffeomorphism invariance. This formulation is then applied to explore potentially observable cosmological effects, shedding light on crucial questions such as how the dynamics of quantum states of matter and geometry can be defined in a diffeomorphism-invariant manner. Moreover, it delves into the relevant space of physical states and the operators that govern them, unraveling the intricate connections between quantum states and probabilities in the absence of a preferred time. By providing answers to these profound inquiries, the book contributes to the ongoing quest for constructing a fundamental theory of quantum gravity. This work is of immense value to graduate students and professional researchers alike, spanning the fields of general relativity and gravitation, cosmology, and quantum foundations.
