In 2000, Martin Bojowald, then a twenty-seven-year-old post-doc at Pennsylvania State University, used a relatively new theory called loop quantum gravity—a cunning combination of Einstein’s theory of gravity with quantum mechanics—to create a simple model of the universe. Loop quantum cosmology was born, and with it, a theory that managed to do something even Einstein’s general theory of relativity had failed to do—illuminate the very birth of the universe. Ever since, loop quantum cosmology, or LQC, has been tantalizing physicists with the idea that our universe could conceivably have emerged from the collapse of a previous one. Now the theory is poised to formulate hypotheses we can actually test. If they are verified, the big bang will give way to the big bounce. Instead of a universe that emerged from a point of infinite density, we will have one that recycles, possibly through an eternal series of expansions and contractions, with no beginning and no end. Bojowald’s major realization was that unlike general relativity, the physics of LQC do not break down at the big bang. The greatest mystery surrounding the origin of the universe is what cosmologists call the big bang “singularity”—the point at the beginning of the universe, prior to the existence of space and time, when gravity, along with the temperature and density of the universe, becomes infinite. The equations of general relativity can’t cope with such infinities, and as a result big bang theory has never been able to give any explanation for the initial condition of our universe, succeeding only in describing and explaining the evolution of the universe from that instant onward. Bojowald’s theory takes us right up to the first moment of the universe—and then back, even before the big bang itself.

Consequences of quantum gravity on grander scales are expected to be enormous: only such a theory can show how black holes really behave and where our universe came from. Applications of loop quantum gravity to cosmology have especially by now shed much light on cosmic evolution of a universe in a fundamental, microscopic description. Modern techniques are explained in this book which demonstrate how the universe could have come from a non-singular phase before the big bang, how equations for the evolution of structure can be derived, but also what fundamental limitations remain to our knowledge of the universe before the big bang. The following topics will be covered in this book: Hamiltonian cosmology: a general basic treatment of isotropy, perturbations and their role for observations; useful in general cosmology. Effective equations: an efficient way to evaluate equations of quantum gravity, which is also useful in other areas of physics where quantum theory is involved. Loop quantization: a new formalism for the atomic picture of space-time; usually presented at a sophisticated mathematical level, but evaluated here from an intuitive physical side. The book will start with physical motivations, rather than mathematical developments which is more common in other expositions of this field. All the required mathematical methods will be presented, but will not distract the reader from seeing the underlying physics. Simple but representative models will be presented first to show the basic features, which are then used to work upwards to a general description of quantum gravity and its applications in cosmology. This will make the book accessible to a more general physics readership.

A Scientific Introduction to Subatomic particles, Alien Intelligence, and Human Space Exploration (For the Cosmically Curious): There are many fundamental questions about the universe that have intrigued scientists, philosophers, and ordinary people for centuries. Here are a few of them: What is the universe made of? This is one of the most basic questions about the universe. Scientists have identified a number of different types of matter and energy, including atoms, subatomic particles, dark matter, and dark energy, but there is still much we don't know. How did the universe begin? The origin of the universe is a subject of intense study and debate. The prevailing theory is the Big Bang, which suggests that the universe began as a singularity and has been expanding ever since. What is the ultimate fate of the universe? Will it keep on expanding indefinitely or will it ultimately come to an end? Some theories suggest that the universe may end in a "big rip" or a "big crunch," while others suggest that it will continue to expand indefinitely. What is the nature of space and time? These are fundamental concepts that are still not fully understood. Some theories suggest that space and time are intertwined and that they can be distorted by the presence of matter and energy. Are there other universes beyond our own? Some theories suggest that our universe may be just one of many in a "multiverse." Although this theory is yet hypothetical, it is a fascinating concept that could have significant ramifications for our comprehension of the cosmos. These are just a few of the many fundamental questions about the universe that scientists and philosophers continue to explore. "Understanding the Universe: Quarks, Leptons and the Big Bang" is a comprehensive exploration of the fundamental principles that govern the universe we live in. From the tiniest particles to the grandest structures in the cosmos, this book takes readers on a journey of discovery through the mysteries of modern physics and cosmology. Starting with an introduction to the basic building blocks of matter, the book delves into the strange world of quarks and leptons, exploring their properties and interactions. It then examines the forces that govern the behavior of matter, including the strong and weak nuclear forces, electromagnetism, and gravity. The book also covers the history of the universe, from its origins in the Big Bang to the present day, and discusses the evolution of stars and galaxies. Readers will gain a deep understanding of the structure of the universe, its expansion, and the mysterious dark matter and dark energy that make up the vast majority of its mass. Filled with engaging examples, clear explanations, and fascinating insights, "Understanding the Universe: Quarks, Leptons and the Big Bang" is a must-read for anyone interested in the inner workings of the cosmos. Whether you're a student of physics, a science enthusiast, or simply curious about the universe, this book will provide you with a solid foundation for understanding the world around us.

For several decades since its inception, Einstein's general theory of relativity stood somewhat aloof from the rest of physics. Paradoxically, the attributes which normally boost a physical theory - namely, its perfection as a theoreti cal framework and the extraordinary intellectual achievement underlying i- prevented the general theory from being assimilated in the mainstream of physics. It was as if theoreticians hesitated to tamper with something that is manifestly so beautiful. Happily, two developments in the 1970s have narrowed the gap. In 1974 Stephen Hawking arrived at the remarkable result that black holes radiate after all. And in the second half of the decade, particle physicists discovered that the only scenario for applying their grand unified theories was offered by the very early phase in the history of the Big Bang universe. In both cases, it was necessary to discuss the ideas of quantum field theory in the background of curved spacetime that is basic to general relativity. This is, however, only half the total story. If gravity is to be brought into the general fold of theoretical physics we have to know how to quantize it. To date this has proved a formidable task although most physicists would agree that, as in the case of grand unified theories, quantum gravity will have applications to cosmology, in the very early stages of the Big Bang universe. In fact, the present picture of the Big Bang universe necessarily forces us to think of quantum cosmology.

Quantum gravity has developed into a fast-growing subject in physics and it is expected that probing the high-energy and high-curvature regimes of gravitating systems will shed some light on how to eventually achieve an ultraviolet complete quantum theory of gravity. Such a theory would provide the much needed information about fundamental problems of classical gravity, such as the initial big-bang singularity, the cosmological constant problem, Planck scale physics and the early-time inflationary evolution of our Universe. While in the first part of this book concepts of quantum gravity are introduced and approached from different angles, the second part discusses these theories in connection with cosmological models and observations, thereby exploring which types of signatures of modern and mathematically rigorous frameworks can be detected by experiments. The third and final part briefly reviews the observational status of dark matter and dark energy, and introduces alternative cosmological models. Edited and authored by leading researchers in the field and cast into the form of a multi-author textbook at postgraduate level, this volume will be of benefit to all postgraduate students and newcomers from neighboring disciplines wishing to find a comprehensive guide for their future research.
