What is the world beyond the Planck scale that provides the minimum unit of the universe? The goal of quantum gravity is to reveal physical laws in such a world. There, quantum fluctuations of gravity become large, and what is called a background-free world where the concept of time and distance is lost shall be realized. The renormalizable quantum gravity introduced in this book offers a theory in which such a world is described by a certain conformal field theory and a deviation from there is handled as a perturbation. This is the state-of-the-art of modern physics that will help in understanding the history of the universe, from its birth to the present.

This book comprehensively describes recent developments in the research of renormalizable quantum gravity, focusing on its application to physics beyond the Planck scale, particularly in inflationary cosmology. It challenges the notion that the Planck scale is an impassable barrier, addressing issues such as singularity, renormalizability, unitarity, time, primordial fluctuations, and the cosmological constant. To describe the trans-Planckian world, it is necessary to break away from the view of graviton scattering and carry out the quantization of spacetime itself. Utilizing conformal field theory techniques to achieve background freedom, the book presents a renormalizable quantum theory of gravity that overcomes the Planck-scale wall. Historically, discussions on renormalizability of gravity declined due to ghost issues. However, ghosts are essential in gravitational systems where the total Hamiltonian/momentum vanishes strictly, for aspects such as cosmic entropy, the formation of the universe, and gravitational objects. Quantum gravity approaches known in recent years often break diffeomorphism invariance or sacrifice renormalizability to eliminate ghosts. In contrast, this book presents a novel attempt which maintains that these are guiding principles even in the trans-Planckian domain, but constrains ghosts to be unphysical. The renormalizability implies a new scale that leads to a quantum gravity inflation scenario with a spacetime phase transition as the Big Bang. This book offers fresh insights into the trans-Planckian physics for graduate students and researchers.

This textbook offers a comprehensible introduction to the physical fundamentals of the processes in our universe. The first chapters cover the observational possibilities of astrophysical quantities, cosmic rays, star formation and evolution, and galaxy formation and modeling. Subsequently, the basics of general relativity and different phenomena such as gravitational waves and black holes are covered. The book concludes with an introduction to cosmology: In addition to traditional homogeneous approaches, inhomogeneous cosmology in particular is given a broader scope in this new edition. Current inflationary models are presented. The book is intended for students of physics at the undergraduate, bachelor, and master levels, but it also offers a readable and easy-to-understand introduction for people with a basic knowledge of mathematics and physics who are interested in the natural sciences. Contents Some important physical basics - observational possibilities - cosmic rays - stellar structure and stellar evolution - final stages of burning stars - galaxies - Newtonian cosmology - computational rules of ART - ART effects - relativistic stars and stellar dynamics - homogeneous cosmology - observations and interpretation approaches - inflation - inhomogeneous cosmology
