Synopsis

Where the science of black holes, gravitational waves, and time travel will likely lead us, as reported by spacetime's most important theoreticians and observers.

Our minds tell us that some things in the universe must be true. The New Physics tells us that they are not, and in the process, blurs the line between science and science fiction. Here are six accessible essays by those who walk that line, moving ever further out in discovering the patterns of nature, aimed at readers who share their fascination with the deepest mysteries of the universe.

· Richard Price: "An Introduction to Spacetime Physics"
· Stephen Hawking: "Chronology Protection"
· Igor Novikov: "Can We Change the Past?"
· Kip S. Thorne: "Speculations about the Future"
· Timothy Ferris: "On the Popularization of Science"
· Alan Lightman: "The Physicist as Novelist"

About this title

About the Author

Stephen W. Hawking is a theoretical physicist and cosmologist. He is an Honorary Fellow of the Royal Society of Arts, a lifetime member of the Pontifical Academy of Sciences, and in 2009 was awarded the Presidential Medal of Freedom, the highest civilian award in the United States.

Kip Thorne, a Nobel Prize-winning physicist and the Feynman Professor of Theoretical Physics Emeritus at Caltech, is the author of the bestselling books Black Holes and Time Warps and The Science of Interstellar. Thorne was an executive producer for the 2014 film Interstellar. For “bridging the worlds of science and the humanities,” Thorne received Rockefeller University’s Lewis Thomas Prize for Writing about Science. He lives in Pasadena, California.

Igor Novikov is a theoretical astrophysicist and cosmologist. He is a Fellow of the Royal Astronomical Society and is a professor of astrophysics at the Observatory of the University of Copenhagen.

Timothy Ferris is a science writer and has held professorships at four universities, teaching subjects as diverse as astronomy, philosophy, English, journalism, and history. He is currently an emeritus professor at UC Berkeley.

Alan Lightman is a physicist and writer. He is a professor at the Massachusetts Institute of Technology. He was the first professor at MIT to receive a joint appointment in the sciences and the humanities.

Richard Price is a leading American physicist, known for his work in general relativity. He is currently a professor at University of Texas Brownsville.

From Scientific American

Put Stephen Hawking, Kip Thorne, Igor Novikov, Timothy Ferris and Alan Lightman in a room together, and I would imagine that the intellectual sparks would fly lively and thick. The five essays collected in this book are adapted from those sparks, talks given at the California Institute of Technology in June 2000 to honor the 60th birthday of physicist Kip Thorne. If there is a unifying theme to the essays, it is the possibility of time travel, one of Thorne's obsessions as a theoretician of general relativity and, of course, a topic of perennial popular interest. None of the authors was paid for his contribution, and royalties will go to a Caltech scholarship fund in Thorne's name. Theoretical physicist Igor Novikov starts by asking, "Can we change the past?" He shows how curious foldings and warpings of spacetime apparently allow the possibility of traveling back in time and considers the so-called grandfather paradox: What if I travel back in time and kill my grandfather? Then, logically, I would never have been born to make my journey into the past. Novikov argues that the laws of nature would prevent such logical paradoxes from happening. Stephen Hawking is perhaps the world's most famous theorist of spacetime. He is less sanguine than Novikov that time travel is possible, except on the scale of individual atomic particles, which is not of much use for science-fiction fantasies. If Hawking's take on the physics is correct, grandfather is doubly safe. Thorne uses his commanding presence at the heart of the book to address the question implicit in the title: How will our understanding of spacetime evolve in the near future, theoretically and experimentally? The final two essays, by writers Timothy Ferris and Alan Lightman, though excellent in themselves, have nothing directly to do with the topic at hand. Ferris considers how science is communicated to the general public, and Lightman muses on relations between science and art. It all adds up to less than the sum of its parts. The word "hodgepodge" comes to mind, and the fact that the editors decided the book needed a long preparatory introduction (longer than all but one of the five contributions) and a puffed-up glossary suggests that the problems were apparent from the beginning. Anyone who wants the skinny on time travel and the future of spacetime would do well to go directly to Thorne's excellent popular book Black Holes and Time Warps: Einstein's Outrageous Legacy (W. W. Norton, 1994). Still, there is a terrific story lurking among the disparate parts of the present volume, but readers will have to dig it out for themselves. I would suggest skipping the introduction and going straight to Lightman's piece on science and art. He was trained as a physicist and has transformed himself into a successful novelist, so he knows both sides of which he speaks. He takes us to the heart of the creative process and shows us what physicists and novelists have in common. For one thing, they both make up stories, and they both want their stories to be true. Ferris tells us why scientific story making is essential to a healthy and free body politic. "Technologically, intellectually, and even politically, science resides somewhere near the center of our culture, by which I mean the society of all those persons who value their freedom, honor their responsibilities, appreciate their ignorance, and are willing to keep learning," he writes. Now go to the essays by Novikov and Hawking and watch two outrageously clever minds at play in the fields of knowledge and ignorance. They take Einstein's supreme story--his theory of gravity and spacetime, called general relativity--and make delightful riffs on the theme. What if? they ask. They agree on this: even if it turns out that time travel is impossible, it is important that we understand why it is impossible. Finally, turn to Thorne's central essay, where it all comes together. We have in Einstein's legacy a fabulously inventive story: black holes, time travel, ripples in spacetime, the big bang--stuff any novelist would have been proud to invent. But the story must be put to the experimental test, and so far general relativity has passed muster. Soon new tests of a most exquisite sensitivity will come on line, and these are the focus of Thorne's crystal-ball gazing. The Laser Interferometer Gravitational Wave Observatory (LIGO)--three huge instruments at Hanford, Wash., and Livingston, La.--and similar devices in Italy, Germany and Japan promise the possibility of detecting gravitational waves rippling through spacetime from colossal events (imploding stars, colliding black holes, even the big bang itself) unfolding across the universe. Then, sometime around 2010 if physicists get their way, the Laser Interferometer Space Antenna (LISA) will be launched into space. Three intercommunicating spacecraft arrayed across millions of kilometers of the solar system, bobbing like corks in water as gravitational waves roll by, will map in fine detail the bending of space, the warping of time, and the whirl of spacetime around distant black holes. LISA will detect ripples in spacetime as small as one hundredth the diameter of an atom. What a story! What a test! This is story making that lifts the human spirit out of our sometimes petty terrestrial concerns and places us among the stars.
