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.

Gravity is one of the four fundamental interactions that exist in nature. It also has the distinction of being the oldest, weakest, and most difficult force to quantize. Understanding gravity is not only essential for understanding the motion of objects on Earth, but also the motion of all celestial objects, and even the expansion of the Universe itself. It was the study of gravity that led Einstein to his profound realisations about the nature of space and time. Gravity is not only universal, it is also essential for understanding the behaviour of the Universe, and all astrophysical bodies within it. In this Very Short Introduction Timothy Clifton looks at the development of our understanding of gravity since the early observations of Kepler and Newtonian theory. He discusses Einstein's theory of gravity, which now supplants Newton's, showing how it allows us to understand why the frequency of light changes as it passes through a gravitational field, why GPS satellites need their clocks corrected as they orbit the Earth, and why the orbits of distant neutron stars speed up. Today, almost 100 years after Einstein published his theory of gravity, we have even detected the waves of gravitational radiation that he predicted. Clifton concludes by considering the testing and application of general relativity in astrophysics and cosmology, and looks at dark energy and efforts such as string theory to combine gravity with quantum mechanics. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

It is in understanding the Gravity of the Matter that surrounds us, that we may possibly someday soon lose the hold that gravity has on us; being able to move across space untethered and unchained by its grasp. Transport to far distant stars and planets in other galaxies may soon be realized. We are living in the early twenty-first century, almost 100 years after Einstein's theories were developed. These theories became the foundation of quantum mechanics and modern theoretical physics that is taught in our schools today. Is it not time to begin questioning these old theories again? As Albert Einstein himself said:“To deny the aether is ultimately to assume that empty space has no physical qualities whatever. The fundamental facts of mechanics do not harmonize with this view…"

A simple explanation of gravity relates to the Higgs mechanism and the Pauli exclusion principle. By the latter, matter cannot occupy the same space other matter occupies, but light energy superimposes to be nearly invisible to other light. By the Higgs mechanism, light energy converts to matter. By its interaction, matter also converts back to light energy. Light speed is also slower in a gravitational field. There is thus a positive field of energy maintaining matter that emits light energy for a vacuum effect consistent with the inverse square law. As a recycling effect, it is also consistent with Einstein's cosmological constant and the cosmological principle of the big bang theory. Tired light is also included for dark energy whereby the Hubble Constant divided by light speed equates the ratio of gravitational force to electromagnetic force.

"This book explores the subject of gravity in a fresh way, taking the reader from Newton to the frontiers of gravitational physics. Per Einstein's general theory of relativity, gravity is a manifestation of the curvature of spacetime, and this is an excellent and robust framework for understanding gravity in many situations. However, physicists nowadays also often understand gravity as the manifestation of a fundamental particle - the graviton - in the same way that we understand electromagnetism as the manifestation of the photon. And, in the very same way that we can "see" light, which is nothing other than an electromagnetic wave propagating through space and time, we can now "hear" gravity in the form of gravitational waves (waves in the very fabric of spacetime). As we celebrate 6 years since the first direct detection of gravitational waves, the reality of these waves, predicted by Einstein's theory of gravity, is now unquestionable. They offer a cutting-edge opportunity to decipher the many mysteries that our Universe is still hiding. What is the origin of the Universe? What are the dark components of the Universe that explain its structure and evolution? What is our fate? In The Beauty of Falling, de Rahm will explore these mysteries, building up a palpable portrait of gravity - what we know and don't know.The book begins with the Newtonian notion of gravitational force and quickly proceeds to Einstein's theory of relativity, while revealing how much more of our picture there is yet to uncover. The author will emphasize that General Relativity predicts its own downfall, and where the theory breaks down - at the particle level - is exactly where scientists are focusing in their search for new physics. The author brings the reader to a new gravitational frontier and, in doing so, introduces her own work - a theory of "massive gravity."While Einstein's theory of gravity assumes that the graviton is massless, "massive gravity" suggests an alternative - that the graviton may indeed have mass and a finite range, meaning that it "switches off" at cosmological scales. This would explain the current accelerating expansion of the universe that is observed. The author interweaves her personal history and research trajectory throughout, explaining the science but also highlighting the adventure of research, the thrill of questioning nature and challenging it in its deepest realization, and the excitement of discovering something entirely new. The story contains setbacks and breakthroughs, from the challenge of being a woman in a field where the representation of women is typically less than 10%, to dealing with the aftermath of challenging the previous claims of a generation of senior scientists (most of whom are men)"--

The birth of a completely new branch of observational astronomy is a rare and exciting occurrence. For a long time, our theories about gravitational waves—proposed by Albert Einstein and others more than a hundred years ago—could never be fully proven, since we lacked the proper technology to do it. That all changed when, on September 14, 2015, instruments at the LIGO Observatory detected gravitational waves for the first time. This book explores the nature of gravitational waves—what they are, where they come from, why they are so significant and why nobody could prove they existed before now. Written in plain language and interspersed with additional explanatory tutorials, it will appeal to lay readers, science enthusiasts, physical science students, amateur astronomers and to professional scientists and astronomers.

Gravity causes an apple to fall to the ground and keeps the moon in orbit around Earth, but it can also trap light for infinity in a dying star and ripple across the cosmos carrying the news of a massive collision between two distant black holes. With accessible language and breathtaking NASA images, students will explore the theory of gravity, from Newton's law of universal gravitation to Einstein's general relativity and beyond. This book supports the Next Generation Science Standards' emphasis on scientific collection and analysis of data and evidence-based theories by discussing the theoretical models scientists devise to describe gravity and the real-world experiments they use to test them.
