Exploring the Early Universe with Gravitational Waves


Book Description

This work investigates gravitational wave production in the early universe and identifies potentially observable features, thereby paving the way for future gravitational wave experiments. It focuses on gravitational wave production in two scenarios: inflation in a model inspired by loop quantum gravity, and preheating at the end of inflation. In the first part, it is demonstrated that gravitational waves’ spectrum differs from the result obtained using ordinary general relativity, with potentially observable consequences that could yield insights into quantum gravity. In the second part, it is shown that the cosmic gravitational wave background is anisotropic at a level that could be detected by future experiments. Gravitational waves promise to be an rich source of information on the early universe. To them, the universe has been transparent from its earliest moments, so they can give us an unobstructed view of the Big Bang and a means to probe the fundamental laws of nature at very high energies.




Waves Passing in the Night


Book Description

From Pulitzer Prize nominee Lawrence Weschler, a fascinating profile of Walter Murch, a film legend and amateur astrophysicist whose investigations could reshape our understanding of the universe. For film aficionados, Walter Murch is legendary--a three-time Academy Award winner, arguably the most admired sound and film editor in the world for his work on Apocalypse Now, The Godfather trilogy, The English Patient, and many others. Outside of the studio, his mind is wide-ranging; his passion, pursued for several decades, has been astrophysics, in particular the rehabilitation of Titius-Bode, a long-discredited 18th century theory regarding the patterns by which planets and moons array themselves in gravitational systems across the universe. Though as a consummate outsider he's had a hard time attracting any sort of comprehensive hearing from professional astrophysicists, Murch has made advances that even some of them find intriguing, including a connection between Titius Bode and earlier notions--going back past Kepler and Pythagorus--of musical harmony in the heavens. Unfazed by rejection, ever probing, Murch perseveres in the highest traditions of outsider science. Lawrence Weschler brings Murch's quest alive in all its seemingly quixotic, yet still plausible, splendor, probing the basis for how we know what we know, and who gets to say. "The wholesale rejection of alternative theories has repeatedly held back the progress of vital science," Weschler observes, citing early twentieth-century German amateur Alfred Wegener, whose speculations about continental drift were ridiculed at first, only to be accepted as fact decades later. Theoretical physicist Lee Smolin says "It is controversy that brings science alive"--and Murch's quest does that in spades. His fascination with the way the planets and their moons are arranged opens up the field of celestial mechanics for general readers, sparking an awareness of the vast and (to us) invisible forces constantly at play in the universe.

Gravitational Waves


Book Description

Gravitational waves were first predicted by Albert Einstein in 1916, a year after the development of his new theory of gravitation known as the general theory of relativity. This theory established gravitation as the curvature of space-time produced by matter and energy. To be discernible even to the most sensitive instruments on Earth, the waves have to be produced by immensely massive objects like black holes and neutron stars which are rotating around each other, or in the extreme situations which prevail in the very early ages of the Universe. This book presents the story of the prediction of gravitational waves by Albert Einstein, the early attempts to detect the waves, the development of the LIGO detector, the first detection in 2016, the subsequent detections and their implications. All concepts are described in some detail, without the use of any mathematics and advanced physics which are needed for a full understanding of the subject. The book also contains description of electromagnetism, Einstein’s special theory and general theory of relativity, white dwarfs, neutron stars and black holes and other concepts which are needed for understanding gravitational waves and their effects. Also described are the LIGO detectors and the cutting edge technology that goes into building them, and the extremely accurate measurements that are needed to detect gravitational waves. The book covers these ideas in a simple and lucid fashion which should be accessible to all interested readers. The first detection of gravitational waves was given a lot of space in the print and electronic media. So, the curiosity of the non-technical audience has been aroused about what gravitational waves really are and why they are so important. This book seeks to answer such questions.




The Biggest Ideas in the Universe


Book Description

INSTANT NEW YORK TIMES BESTSELLER “Most appealing... technical accuracy and lightness of tone... Impeccable.”—Wall Street Journal “A porthole into another world.”—Scientific American “Brings science dissemination to a new level.”—Science The most trusted explainer of the most mind-boggling concepts pulls back the veil of mystery that has too long cloaked the most valuable building blocks of modern science. Sean Carroll, with his genius for making complex notions entertaining, presents in his uniquely lucid voice the fundamental ideas informing the modern physics of reality. Physics offers deep insights into the workings of the universe but those insights come in the form of equations that often look like gobbledygook. Sean Carroll shows that they are really like meaningful poems that can help us fly over sierras to discover a miraculous multidimensional landscape alive with radiant giants, warped space-time, and bewilderingly powerful forces. High school calculus is itself a centuries-old marvel as worthy of our gaze as the Mona Lisa. And it may come as a surprise the extent to which all our most cutting-edge ideas about black holes are built on the math calculus enables. No one else could so smoothly guide readers toward grasping the very equation Einstein used to describe his theory of general relativity. In the tradition of the legendary Richard Feynman lectures presented sixty years ago, this book is an inspiring, dazzling introduction to a way of seeing that will resonate across cultural and generational boundaries for many years to come.

Biocentrism


Book Description

Robert Lanza is one of the most respected scientists in the world a US News and World Report cover story called him a genius and a renegade thinker, even likening him to Einstein. Lanza has teamed with Bob Berman, the most widely read astronomer in the world, to produce Biocentrism, a revolutionary new view of the universe. Every now and then a simple yet radical idea shakes the very foundations of knowledge. The startling discovery that the world was not flat challenged and ultimately changed the way people perceived themselves and their relationship with the world. For most humans of the 15th century, the notion of Earth as ball of rock was nonsense. The whole of Western, natural philosophy is undergoing a sea change again, increasingly being forced upon us by the experimental findings of quantum theory, and at the same time, toward doubt and uncertainty in the physical explanations of the universes genesis and structure. Biocentrism completes this shift in worldview, turning the planet upside down again with the revolutionary view that life creates the universe instead of the other way around. In this paradigm, life is not an accidental byproduct of the laws of physics. Biocentrism takes the reader on a seemingly improbable but ultimately inescapable journey through a foreign universe our own from the viewpoints of an acclaimed biologist and a leading astronomer. Switching perspective from physics to biology unlocks the cages in which Western science has unwittingly managed to confine itself. Biocentrism will shatter the readers ideas of life--time and space, and even death. At the same time it will release us from the dull worldview of life being merely the activity of an admixture of carbon and a few other elements; it suggests the exhilarating possibility that life is fundamentally immortal. The 21st century is predicted to be the Century of Biology, a shift from the previous century dominated by physics. It seems fitting, then, to begin the century by turning the universe outside-in and unifying the foundations of science with a simple idea discovered by one of the leading life-scientists of our age. Biocentrism awakens in readers a new sense of possibility, and is full of so many shocking new perspectives that the reader will never see reality the same way again.

Schroedinger's Universe and the Origin of the Natural Laws


Book Description

Schrödinger's Universe: Einstein, Waves and the Origin of the Natural Laws Erwin Schrodinger (1937) perceived that the whole Universe, what we observe as material bodies and forces, are nothing but shapes and variations in the structure of space. When he and Einstein debated the particle theorists led by Neils Bohr, most scientists thought they had lost it. This book shows they were right; that all matter is one Wave Structure in the space of the Universe. If the stars did not exist, we could not exist.
