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.

An award-winning theoretical physicist and best-selling author of A Universe from Nothing traces the dramatic discovery of the counterintuitive world of reality, explaining how readers can shift their perspectives to gain greater understandings of our individual roles in the universe. --Publisher.

Bestselling author and acclaimed physicist Lawrence Krauss offers a paradigm-shifting view of how everything that exists came to be in the first place. “Where did the universe come from? What was there before it? What will the future bring? And finally, why is there something rather than nothing?” One of the few prominent scientists today to have crossed the chasm between science and popular culture, Krauss describes the staggeringly beautiful experimental observations and mind-bending new theories that demonstrate not only can something arise from nothing, something will always arise from nothing. With a new preface about the significance of the discovery of the Higgs particle, A Universe from Nothing uses Krauss’s characteristic wry humor and wonderfully clear explanations to take us back to the beginning of the beginning, presenting the most recent evidence for how our universe evolved—and the implications for how it’s going to end. Provocative, challenging, and delightfully readable, this is a game-changing look at the most basic underpinning of existence and a powerful antidote to outmoded philosophical, religious, and scientific thinking.

"Assume the cow is a sphere." So begins this lively, irreverent, and informative look at everything from the physics of boiling water to cutting-edge research at the observable limits of the universe. Rich with anecdotes and accessible examples, Fear of Physics nimbly ranges over the tools and thought behind the world of modern physics, taking the mystery out of what is essentially a very human intellectual endeavour.

Lawrence Krauss explores the greatest unanswered questions at the forefront of science today, and likely for the coming century and beyond. Internationally known theoretical physicist and bestselling author Lawrence Krauss explores science’s greatest unanswered questions. Three of the most important words in science are “I don't know.” Not knowing implies a Universe of opportunities—the possibility of discovery and surprise. Our understanding of science has advanced immeasurably over the last five hundred years, yet many fundamental mysteries of existence persist: How did our Universe begin? How big is the Universe? Is time travel possible? What’s at the center of a black hole? How did life on Earth arise? Are we alone? What is consciousness, and can we create it? These mysteries define the scientific forefront—the threshold of the unknown. To explore that threshold is to gain a deeper understanding of just how far science has progressed. Covering time, space, matter, life, and consciousness, Krauss introduces readers to topics that will shape the state of science for the next century, providing us all passport to our own journeys of exploration and discovery.

“Brilliant and fundamental, this is the necessary book about our prime global emergency. Here you’ll find the facts, the processes, the physics of our complex and changing climate, but delivered with eloquence and urgency. Lawrence Krauss writes with a clarity that transcends mere politics. Prose and poetry were never better bedfellows.” —Ian McEwan, Booker Prize-winning author of Solar and Machines Like Me "The ideal book for understanding the science of global warming..at once elegant, rigorous, and timely." — Elizabeth Kolbert, Pulitzer Prizewinning author of The Sixth Extinction “A brief, brilliant, and charming summary of what physicists know about climate change and how they learned it.” —Sheldon Glashow, Nobel Laureate in Physics, Metcalf Distinguished Professor Emeritus, Boston University “The distinguished scientist Lawrence Krauss turns his penetrating gaze on the most pressing existential threat facing our world: climate change. It is brimming with information lucidly analysed. Such hope as there is lies in science, and a physicist of Dr. Krauss’s imaginative versatility is unusually qualified to offer it.” —Richard Dawkins, author of The Blind Watchmaker and Science in the Soul “Lucid and gripping, this study of the most severe challenge humans have ever faced leads the reader from the basic physics of climate change to recognition of the damage that humans have already caused and on to the prospects that lie ahead if we do not change course soon.” —Noam Chomsky, Laureate Professor, University of Arizona, author of Internationalism or Extinction? “Lawrence Krauss tells the story of climate change with erudition, urgency, and passion. It is our great good luck that one of our most brilliant scientists is also such a gifted writer. This book will change the way we think about the future.” —Jennifer Finney Boylan, author of Good Boy and She’s Not There “Everything on climate change that I’ve seen is either dumbed down and bossy or written for other climate scientists. I’ve been looking for a book that can let me, a layperson, understand the science. This book does just what I was looking for. It is important.” —Penn Jillette, Magician, author of Presto! and God, No! “The renowned physicist Lawrence Krauss makes the science behind one of the most important issues of our time accessible to all.” —Richard C. J. Somerville, Distinguished Professor Emeritus, Scripps Institution of Oceanography, University of California, San Diego “Lawrence Krauss is a fine physicist, a talented writer, and a scientist deeply engaged with public affairs. His book deserves wide readership. The book’s eloquent exposition of the science and the threats should enlighten all readers and motivate them to an urgent concern about our planet’s future.” —Lord Martin Rees, Astronomer Royal, former president of the Royal Society, author of On the Future: Prospects for Humanity

The national bestselling author of The Physics of Star Trek returns with an “enthusiastic and entertaining” journey through the science of the cosmos (The Guardian, UK). Taking us on a millennia-spanning journey through the life of a single oxygen atom, physicist and author Lawrence M. Krauss traces the history of the cosmos from the Big Bang to the present—and on into the distant future. With wit and insight, Krauss explicates cutting-edge science and reveals the surprising story of matter: what it is, where it came from, and where it’s going. Along the way, this lively and accessible volume inspires wonder at the powers and unlikely events that conspired to create our solar system, our ecosystem, and us. “Lawrence Krauss has Carl Sagan’s knack of expanding the imagination and explaining the mysteries of the universe in simple terms.” —Stephen Hawking

Will the universe continue to expand forever, reverse its expansion and begin to contract, or reach a delicately poised state where it simply persists forever? The answer depends on the amount and properties of matter in the universe, and that has given rise to one of the great paradoxes of modern cosmology; there is too little visible matter to account for the behaviour we can see. Over 90 percent of the universe consists of 'missing mass' or 'dark matter' - what Lawrence Krauss, in his classic book, termed "the fifth essence". In this new edition of The Fifth Essence, retitled Quintessence after the now widely accepted term for dark matter, Krauss shows how the dark matter problem is now connected with two of the hottest areas in recent cosmology: the fate of the universe and the "cosmological constant." With a new introduction, epilogue and chapter updates, Krauss updates his classic and shares one of the most stunning discoveries of recent years: an antigravity force that explains recent observations of a permanently expanding universe.

An unparalleled group of prominent scholars from wide-ranging disciplines detail ongoing efforts to impose ideological restrictions on science and scholarship throughout western society. From assaults on merit-based hiring to the policing of language and replacing well-established, disciplinary scholarship by ideological mantras, current science and scholarship is under threat throughout western institutions. As this group of prominent scholars ranging across many different disciplines and political leanings detail, the very future of free inquiry and scientific progress is at risk. Many who have spoken up against this threat have lost their positions, and a climate of fear has arisen that strikes at the heart of modern education and research. Banding together to finally speak out, this brave and unprecedented group of scholars issues a clarion call for change. Topics include: Free speech, victimhood, ideology, corruption of academic disciplines, cancel culture, DEI, gender, and race, and what we can do. “Higher education isn’t what it used to be. Cancel Culture and DEI have caused many to keep their mouths shut. Not so the authors of this book. This collection of essays tells of threats to open inquiry, free speech, and the scientific process itself. A much-needed book.”—Sabine Hossenfelder, Physicist and Author of Existential Physics: A Scientist’s Guide to Life’s Biggest Questions With Contributions by: Dorian Abbot, John Armstrong, Peter Boghossian, Maarten Boudry, Alex Byrne, Nicholas Christakis, Roger Cohen, Jerry Coyne, Richard Dawkins, Niall Ferguson, Janice Fiamengo, Solveig Gold, Moti Gorin, Karleen Gribble, Carole Hooven, Geoff Horsman, Joshua Katz, Sergiu Klainerman, Lawrence M.

Since the 19th century, physicists have talked a private language they share only with mathematicians. And, since the 1920s, physics has not even shared our everyday idea of space and time - the sub-atomic world of the quantum seems to be ruled by weirder rules than we can understand. This book cuts through the maths and the strangeness to the underlying concepts, the basic intuitions about the way the world works that guide the researchers of physics such as Feynman, Hawking, Penrose and Weinberg. Lawrence Krauss is the author of The Fifth Essence.
