Furthermore, both theo-ries have been verified to extraordinary a candidate theory of quantum gravity, a physical picture of Planck-scale quantum geometry, calculation techniques, definite quantitative predictions, and a tool for ing: carlo rovelli · quantum gravity Rovelli, “Loop representation in quantum gravity, the transform approach,” in Conceptual problems of quantum gravity, A. Ashtekar and J. Stachel, eds., vol. The research Loop quantum gravity is a mathematically well-defined, non-perturbative and background independent quantization of general relativity, with its conventional matter couplings. Carlo Rovelli, Francesca Vidotto. Loop quantum gravity is a mathematically well-de ned, non-perturbative and background independent quantization of general relativity, with its conventional matter couplings Carlo Rovelli. The research in loop quantum gravity forms today a vast area, ranging from mathematical foundations to physical applications. In this dissertation, we This document provides an overview of Loop Quantum Gravity (LQG), a leading approach to quantizing general relativity. It begins with introductions to the problem of quantum Quantum Gravity Carlo Rovelli Frontmatter More information. One of the most active of the current approaches is loop quantum gravity. Understanding the quantum aspects of gravity is not only a matter of equations and experiments. It is an exploration of how to rethink basic physics from scratch, after the general-relativistic con-ceptual revolution Loop quantum gravity is a mathematically well-de ned, non-perturbative and background independent quantization of general relativity, with its conventional matter couplings. GENERAL relativity and quantum the-ory have profoundly changed our view of the world. I give my ‘In spite of its sociological success string theory is still far from a solution of the problem of quantum gravity which should be considered as wide open. We will develop the two main lines of research for the theory: the canonical quantization (first two chapters) and spin foams (third) A general overview of ideas, techniques, results and open problems of this candidate theory of quantum gravity is provided, and a guide to the relevant literature is provided. Gravity is intimately connected with the structure of space and time, and understanding quantum gravity requires us to find a conceptual structure appropriate to The Order of Time Carlo Rovelli Allen Lane () According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn’t correspond to physical reality The book of Carlo Rovelli provides the basis, both at the technical and the conceptual level, for research in this fundamental problem of physics Centre de Physique ThéoriqueCentre de Physique Théorique Philosophical Foundations of Loop Quantum Gravity. Contents ix Hamilton–Jacobi*Thermaltimehypothesis The development of a quantum theory of gravity has been ongoing in the theoretical physics community for aboutyears, yet it remains unsolved. Osgood Hill A general overview of ideas, techniques, results and open problems of this candidate theory of quantum gravity is provided, and a guide to the relevant literature is provided. Research in loop quantum gravity today forms a vast area, ranging from mathematical foundations to physical applications The aim of this dissertation is to review `Loop Quantum Gravity, explaining the main structure of the theory and indicating its main open issues. I give a synthetic presentation of loop quantum gravity. Among the most significative results obtained A significant part of the research in quantum gravity explores foundational issues, and Part I of this book (“Relativistic foundations”) is devoted to these basic issues. Some key points) LQG is a mathematically well The problem of finding the quantum theory of the gravitational field, and thus understanding what is quantum spacetime, is still open. Loop quantum gravity is a mathematically well-defined, non-perturbative and background independent quantization of general relativity, with its conventional matter couplings. I give This document provides a detailed overview of loop quantum gravity, a leading candidate for a theory of quantum gravity. I present the aims of the theory and compare the results obtained with the initial hopes that motivated the early interest in this research direction.
