A unified theory embracing all physical phenomena is a major goal of theoretical physics. In the early 1980s, many physicists looked to eleven-dimensional supergravity in the hope that it might provide that elusive superunified theory. In 1984 supergravity was knocked off its pedestal by ten-dimensional superstrings, one-dimensional objects whose v

Delve into the fascinating world of String Theory with this comprehensive guide that covers everything from the basics of Quantum Mechanics to the challenges and future directions in the field. Explore the connections between String Theory and Quantum Gravity, delve into the mysteries of the Multiverse, and uncover the intricate relationships between String Theory and Mathematics. Packed with insights and explanations, this book is a must-have for anyone interested in the cutting-edge theories that are shaping our understanding of the universe.

Presented in clear and accessible language with wonderfully supportive graphics, Roberts offers the reader a voyage through the development of human knowledge. He then examines the outstanding mysteries of modern physics-the phenomena that lie outside the boarders of our current understanding (dark energy, dark matter, the Big Bang, wave-particle duality, quantum tunneling, state vector reduction, etc.) and suggests that the next step in our intellectual journey is to treat the vacuum of space as a superfluid-modeling it as being composed of interactive quanta, which, in a self similar way, are composed of subquanta, and so on. With this proposition Roberts engenders the vacuum with fractal geometry, and opens the door to explaining the outstanding mysteries of physics geometrically. Roberts' model, called quantum space theory, has been praised for how it offers an intuitively accessible picture of eleven-dimensions and for powerfully extending the insight of general relativity, eloquently translating the four forces into unique kinds of geometric distortions, while offering underlying deterministic dynamics that give rise to quantum mechanics. That remarkably simple picture explains the mysteries of modern physics in a way that is fully commensurate with Einstein's intuition. It is a refreshingly unique perspective that generates several testable predictions. "This work is mathematically beautiful and scientifically priceless, and the kicker is that it comes with a vivid and satisfying picture." Chris J. Wilshaw "This book fundamentally changed my understanding of our universe." Matt Emmi

The universe has many secrets. It may hide additional dimensions of space other than the familier three we recognize. There might even be another universe adjacent to ours, invisible and unattainable . . . for now. Warped Passages is a brilliantly readable and altogether exhilarating journey that tracks the arc of discovery from early twentieth-century physics to the razor's edge of modern scientific theory. One of the world's leading theoretical physicists, Lisa Randall provides astonishing scientific possibilities that, until recently, were restricted to the realm of science fiction. Unraveling the twisted threads of the most current debates on relativity, quantum mechanics, and gravity, she explores some of the most fundamental questions posed by Nature—taking us into the warped, hidden dimensions underpinning the universe we live in, demystifying the science of the myriad worlds that may exist just beyond our own.

The national bestselling author of The God Equation takes us on a thrilling journey to explore black holes and time machines, multidimensional space and the possibility that parallel universes may lay alongside our own. “A wonderful tour, with an expert guide.” —Brian Greene, New York Times bestselling author of The Elegant Universe Kaku skillfully guides us through the latest innovations in string theory and its latest iteration, M-theory, which posits that our universe may be just one in an endless multiverse, a singular bubble floating in a sea of infinite bubble universes. If M-theory is proven correct, we may perhaps finally find answer to the question, “What happened before the big bang?” This is an exciting and unforgettable introduction into the new cutting-edge theories of physics and cosmology from one of the pre-eminent voices in the field.
