Book Description
Top researchers in the field of gravitation present the state-of-the-art topics outlined in this book, ranging from the stability of rotating wormholes solutions supported by ghost scalar fields, modified gravity applied to wormholes, the study of novel semi-classical and nonlinear energy conditions, to the applications of quantum effects and the superluminal version of the warp drive in modified spacetime. Based on Einstein's field equations, this cutting-edge research area explores the more far-fetched theoretical outcomes of General Relativity and relates them to quantum field theory. This includes quantum energy inequalities, flux energy conditions, and wormhole curvature, and sheds light on not just the theoretical physics but also on the possible applications to warp drives and time travel. This book extensively explores the physical properties and characteristics of these 'exotic spacetimes,' describing in detail the general relativistic geometries that generate closed timelike curves.

Book Description
For the past 20 years causality violations and superluminal motion have been the object of intensive study as physical and geometrical phenomena. This book compiles the results of its author and also reviews other work in the field. In particular, the following popular questions are addressed: Is causality protected by quantum divergence at the relevant Cauchy horizon? How much "exotic matter" would it take to create a time machine or a warp drive? What is the difference between a "discovered" time machine and a created one? Why does a time traveler fail to kill their grandfather? How should we define the speed of gravity and what is its magnitude?

Book Description
How does the Star Trek universe stack up against the real universe? What warps when you're traveling at warp speed? What is the difference between a wormhole and a black hole? Are time loops really possible, and can I kill my grandmother before I am born? Anyone who has ever wondered "could this really happen?" will gain useful insights into the Star Trek universe (and, incidentally, the real world of physics) in this charming and accessible guide. Lawrence M. Krauss boldly goes where Star Trek has gone-and beyond. From Newton to Hawking, from Einstein to Feynman, from Kirk to Picard, Krauss leads readers on a voyage to the world of physics as we now know it and as it might one day be.

Book Description
This book is for anyone who wants a fresh approach to modern physics. Are you tired of amusing anecdotes about scientists' personal lives and eureka moments? Bored of chronological narratives of scientific progress through the ages? No longer wowed by ideas like string theory? Interested in first principles thinking and what it can do for you? This book is for you. This book is designed to take you step by step through the fundamental principles that underlie the physics of space, time, and matter. It is a how-to guide for building up our universe from first principles. By posing questions and answering them with illustrations and examples, the book shows how we can demonstrate what we know about the universe with simple concepts and thought experiments. With this book, you too can apply first principles to build up your own model of the universe and how it works, one you can take with you, and apply it to other areas of your life such as your job, business, even your relationships. There are no complicated mathematics in this book and I have minimized the amount of jargon. Thus, it is suitable anyone of any educational background from high school on. The book aims to be straightforward about how we get from simple ideas to complex physical theories. So, if you are interested in a new way of looking at the universe and are not afraid to unlearn some of what you have learned, take a look inside.

Book Description
A Princeton astrophysicist explores whether journeying to the past or future is scientifically possible in this “intriguing” volume (Neil deGrasse Tyson). It was H. G. Wells who coined the term “time machine”—but the concept of time travel, both forward and backward, has always provoked fascination and yearning. It has mostly been dismissed as an impossibility in the world of physics; yet theories posited by Einstein, and advanced by scientists including Stephen Hawking and Kip Thorne, suggest that the phenomenon could actually occur. Building on these ideas, J. Richard Gott, a professor who has written on the subject for Scientific American, Time, and other publications, describes how travel to the future is not only possible but has already happened—and contemplates whether travel to the past is also conceivable. This look at the surprising facts behind the science fiction of time travel “deserves the attention of anyone wanting wider intellectual horizons” (Booklist). “Impressively clear language. Practical tips for chrononauts on their options for travel and the contingencies to prepare for make everything sound bizarrely plausible. Gott clearly enjoys his subject and his excitement and humor are contagious; this book is a delight to read.” —Publishers Weekly

Book Description
Many physical properties of our universe, such as the relative strength of the fundamental interactions, the value of the cosmological constant, etc., appear to be fine-tuned for existence of human life. One possible explanation of this fine tuning assumes existence of a multiverse, which consists of a very large number of individual universes having different physical properties. Intelligent observers populate only a small subset of these universes, which are fine-tuned for life. In this book we will review several interesting metamaterial systems, which capture many features of important cosmological models and offer insights into the physics of many other non-trivial spacetime geometries, such as microscopic black holes, closed time-like curves (CTCs) and the Alcubierre warp drive.

Book Description
Time travel is not just science fiction; it may actually be possible. Wolf draws on yoga and quantum physics to show that time is a flexible projection of mind. Cheating time, he says, is an ancient metaphysical idea from the Vedas having to do with moving through meditation to a place where time stands still.

Book Description
"Delightful, funny, and yet rigorous and intelligent: only Jorge and Daniel can reach this exquisite balance." —Carlo Rovelli, author of Seven Brief Lessons on Physics and Helgoland You’ve got questions: about space, time, gravity, and the odds of meeting your older self inside a wormhole. All the answers you need are right here. As a species, we may not agree on much, but one thing brings us all together: a need to know. We all wonder, and deep down we all have the same big questions. Why can’t I travel back in time? Where did the universe come from? What’s inside a black hole? Can I rearrange the particles in my cat and turn it into a dog? Researcher-turned-cartoonist Jorge Cham and physics professor Daniel Whiteson are experts at explaining science in ways we can all understand, in their books and on their popular podcast, Daniel and Jorge Explain the Universe. With their signature blend of humor and oh-now-I-get-it clarity, Jorge and Daniel offer short, accessible, and lighthearted answers to some of the most common, most outrageous, and most profound questions about the universe they’ve received. This witty, entertaining, and fully illustrated book is an essential troubleshooting guide for the perplexing aspects of reality, big and small, from the invisible particles that make up your body to the identical version of you currently reading this exact sentence in the corner of some other galaxy. If the universe came with an FAQ, this would be it.

Book Description
The most successful and controversial Cuban Science Fiction writer of all time, Yoss (aka José Miguel Sánchez Gómez) is known for his acerbic portraits of the island under Communism. In his bestselling A Planet for Rent, Yoss pays homage to Ray Bradbury’s The Martian Chronicles and 334 by Thomas M. Disch. A critique of Cuba in the nineties, after the fall of the Soviet Union and the dissolution of the Warsaw Pact, A Planet for Rent marks the debut in English of an astonishingly brave and imaginative Latin American voice. Praise for Yoss “One of the most prestigious science fiction authors of the island.” —On Cuba Magazine "A gifted and daring writer." —David Iaconangelo "José Miguel Sánchez [Yoss] is Cuba’s most decorated science fiction author, who has cultivated the most prestige for this genre in the mainstream, and the only person of all the Island’s residents who lives by his pen.” —Cuenta Regresiva Born José Miguel Sánchez Gómez, Yoss assumed his pen name in 1988, when he won the Premio David Award in the science fiction category for Timshel. Together with his peculiar pseudonym, the author's aesthetic of an impentinent rocker has allowed him to stand out amongst his fellow Cuban writers. Earning a degree in Biology in 1991, he went on to graduate from the first ever course on Narrative Techniques at the Onelio Jorge Cardoso Center of Literary Training, in the year 1999. Today, Yoss writes both realistic and science fiction works. Alongside these novels, the author produces essays, Praise for, and compilations, and actively promotes the Cuban science fiction literary workshops, Espiral and Espacio Abierto. When he isn’t translating, David Frye teaches Latin American culture and society at the University of Michigan. Translations include First New Chronicle and Good Government by Guaman Poma de Ayala (Peru, 1615); The Mangy Parrot by José Joaquín Fernandez de Lizardi (Mexico, 1816), for which he received a National Endowment for the Arts Fellowship; Writing across Cultures: Narrative Transculturation in Latin America by Ángel Rama (Uruguay, 1982), and several Cuban and Spanish novels and poems.
