The unification between gravity and quantum field theory is one of the major problems in contemporary fundamental Physics. This book presents a series of selected chapters written by renowned authors. Each chapter treats gravity and its quantization through known and alternative techniques, aiming a deeper understanding on the quantum nature of gravity.

An overview of attempts to describe gravity as an emergent phenomenon, starting from condensed matter physics to more sophisticated pregeometric models. The common line of thought is to view the graviton as a composite particle/collective moode.
by Stephen Hawking, Roger Penrose - arXiv
Stephen Hawking and Roger Penrose put forward their related but rather different viewpoints on the nature of space and time. They discuss their different approaches. A basic knowledge of general relativity and quantum theory is assumed.

This article reviews the present status of the spin foam approach to the quantization of gravity. Special attention is payed to the pedagogical presentation of the recently introduced new models for four dimensional quantum gravity.
by Bryce S. DeWitt, Giampiero Esposito - arXiv
The reader is introduced to the functional integral quantization of gravitation and Yang-Mills theory. The text is useful for all Ph.D. students who face the task of learning some basic concepts in quantum gravity in a relatively short time.
