The holy grail of theoretical physics is to find the theory of everything that combines all the forces of nature, including gravity. This book addresses the question: how far are we from such discovery? Over the last few decades, multiple roads to finding a quantum theory of gravity have been proposed but no obvious description of nature has emerged in this domain. What is to be made of this situation? This volume probes the state-of-the art in this daunting quest of theoretical physics by collecting critical interviews with nearly forty leading theorists in this field. These broad-ranging conversations give important insights and candid opinions on the various approaches to quantum gravity, including string theory, loop quantum gravity, causal set theory and asymptotic safety. This unique, readable overview provides a gateway into cutting edge research for students and others who wish to engage with the open problem of quantum gravity.

This book presents a collection of chapters in which researchers who have worked in the field of gravity for years reveal their visions of the origin of gravity. Some approaches are based on field equations and ideas of general relativity, but others suggest their own procedures. Among the visions we see the further development of principles of general relativity, which unify gravity with fluctuations of matter or a background of super-strong interacting gravitons, as well as visions that ignore complicated interactions of gravity with other fields altogether. There is also a new approach in which space-particle dualism is presented. In addition, there is the approach that suggests starting directly with the smallest granularity of space, defined by the Planck scale. These lines of study involve constructions and methods emerging from quantum mechanical formalism and even suggestions for new courses of action, such as subquantum kinetics and submicroscopic mechanics. These approaches all try to explain the concepts of particle, mass, and their interactions. These are new trends both in the theory of gravitation and in the theory of elementary particles, and hence fundamental physics in general.

Currently, the General Theory of Relativity (GTR) describes the physics of the very large in terms of classical physics, while quantum theory describes the physics of the very small in terms of the Standard Model of particle physics. Unfortunately, the two theories are incompatible and do not describe satisfactorily all the forces between the various particles comprising ordinary matter. At present, one of the deepest problems in theoretical physics is harmonizing the GTR, which describes gravitation, with quantum mechanics, which describes the other three fundamental forces acting on the atomic scale. The main aim of the book is to provide an understanding of gravity in terms of a quantum theory given by the Generation Model of particle physics. The book presents a fully quantum theory of gravity, which describes both the large cosmological scale and the small atomic scale interactions between all particles.

Quantum Gravity, Light, and Sound by Gerald W. Scanlon

Imagine if you were taking a walk along the beach. What sounds would you hear? What colors would you see? It is easy to answer those questions because we have experience living in the classical realm of physics of Newton and Einstein, where objects have definite form and interact in clearly determinate ways. Now, imagine if you were an electron whirling around the nucleus of an atom. Would you hear any sounds or see any colors? Those questions are not easy to answer because we can't experience the quantum realm, where objects are more difficult to describe, since they have a strange mix of particle-like and wave-like behavior. How about gravity? How would you experience it as an electron? The standard model of particle physics provides a framework for the weak, strong and electromagnetic forces of the quantum realm. Gravity, however, remains outside the grasp of scientists to fit it into the framework.In this book, the author uses quantum geometry to formulate a new atomic model similar to the Bohr model and the electron cloud model. The proposed atomic model shows mathematical calculations and graphic designs to demonstrate the presence of gravity on a geometrical framework. It also provides various geometrical figures so one can visualize electrons whirling around the nucleus of an atom in an array of colors and creating a symphony of sounds as they jump from one orbital to the next in quantum leaps.
