Faster Than Light

Author: Nick Herbert
Publisher: Penguin
ISBN: 0452263174
Category : Science
Languages : en
Pages : 225

Book Description
"Even though most physicists believe that the speed of light is as fast as anyone can go, Einstein's theory of special relativity does not rule out faster-than-light (FTL) travel. On the contrary, it seems to indicate that certain superluminal or FTL effects would permit us to re-experience the past: time travel would become a reality, not science fiction. Through this crack in the cosmic egg steps Herbert, a Stanford physicist and author of Quantum Reality, who summarizes clearly current speculation and theory about faster-than-light travel. Along with space warps, black holes and tachyons (hypothetical FTL particles), he looks at the so-called 'quantum connection'—an alleged force said to instantaneously link any two subatomic particles long after they have bumped into each other. Free of the woolgathering that tints much writing on the 'new physics', this brave, exciting book should send scientists back to their drawing boards; for the nonspecialist reader, it reveals a world much stranger than Star Trek."—Publishers Weekly "Original, challenging, and audacious."—San Diego Magazine

Faster Than Light

Author: Marilyn Nelson
Publisher: LSU Press
ISBN: 0807147338
Category : Poetry
Languages : en
Pages : 0

Book Description
Conjuring numerous voices and characters across oceans and centuries, Faster Than Light explores widely disparate experiences through the lens of traditional poetic forms. This volume contains a selection of Marilyn Nelson's new and uncollected poems as well as work from each of her lyric histories of eighteenth-, nineteenth-, and twentieth-century African American individuals and communities. Poems include the stories of historical figures like Emmett Till, the fourteen-year-old boy lynched in 1955, and the inhabitants of Seneca Village, an African American community razed in 1857 for the creation of Central Park. "Bivouac in a Storm" tells the story of a group of young soldiers, later known as the Tuskegee Airmen, as they trained near Biloxi, Mississippi, "marching in summer heat / thick as blackstrap molasses, under trees / haunted by whippings." Later pieces range from the poet's travels in Africa, Europe, and Polynesia, to poems written in collaboration with Father Jacques de Foiard Brown, a former Benedictine monk and the subject of Nelson's playful fictional fantasy sequence, "Adventure-Monk!" Both personal and historical, these poems remain grounded in everyday details but reach toward spiritual and moral truths.

Back-in-Time and Faster-than-Light Travel in General Relativity

Author: Serguei Krasnikov
Publisher: Springer
ISBN: 3319727540
Category : Science
Languages : en
Pages : 255

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?

Special Relativity and Motions Faster than Light

Author: Moses Fayngold
Publisher: John Wiley & Sons
ISBN: 3527622438
Category : Science
Languages : de
Pages : 320

Book Description
While the theory of special relativity is often associated with the idea of traveling faster than light, this book shows that in all these cases subtle forces of nature conspire to prevent these motions being harnessed to send signals faster than the speed of light. The author tackles these topics both conceptually, with minimal or no mathematics, and quantitatively, making use of numerous illustrations to clarify the discussion. The result is a joy to read for both scientists familiar with the subject and laypeople wishing to understand something of special relativity.

Hunting the Faster than Light Tachyon, and Finding Three Unicorns and a Herd of Elephants

Author: Robert Ehrlich
Publisher: CRC Press
ISBN: 1000587991
Category : Science
Languages : en
Pages : 222

Book Description
In 1905, Albert Einstein declared speeds greater than light to be impossible. This book describes the author’s decades-long search for the hypothetical subatomic particles known as tachyons that violate this principle. This book is a scientific detective story. The crime is speeding—that is, the possible breaking of the cosmic speed limit, namely the speed of light, as stipulated by Einstein. This detective story is also a memoir written by a member of a band of "tachyon hunters." The author’s pursuit of tachyons has been met with skepticism from most physicists, who note correctly that no such superluminal particles have ever been surely observed and that there have been many false sightings. Nevertheless, considerable circumstantial evidence for tachyons has already been published and an ongoing experiment could decide the issue in the next few years. This book is written for the general reader, containing humor and eliminating jargon whenever possible, and will also be of interest to scientists. The hunt for the tachyon will fascinate all readers who approach the study of physics with curious and open minds.

Cycles of Time

Author: Roger Penrose
Publisher: Vintage
ISBN: 0307596745
Category : Science
Languages : en
Pages : 307

Book Description
From Nobel prize-winner Roger Penrose, this groundbreaking book is for anyone "who is interested in the world, how it works, and how it got here" (New York Journal of Books). Penrose presents a new perspective on three of cosmology’s essential questions: What came before the Big Bang? What is the source of order in our universe? And what cosmic future awaits us? He shows how the expected fate of our ever-accelerating and expanding universe—heat death or ultimate entropy—can actually be reinterpreted as the conditions that will begin a new “Big Bang.” He details the basic principles beneath our universe, explaining various standard and non-standard cosmological models, the fundamental role of the cosmic microwave background, the paramount significance of black holes, and other basic building blocks of contemporary physics. Intellectually thrilling and widely accessible, Cycles of Time is a welcome new contribution to our understanding of the universe from one of our greatest mathematicians and thinkers.

Faster Than The Speed Of Light

Author: Joao Magueijo
Publisher: Random House
ISBN: 144813403X
Category : Science
Languages : en
Pages : 312

Book Description
The idea that the speed of light is a constant - at 186,000 miles per second - is one of the few scientific facts that almost everyone knows. That constant - c- also appears in the most famous of all scientific equations: e=mc2- Yet over the last few years, a small group of highly reputable young physicists have suggested that the central dogma of modern physics may not be an absolute truth - light may have moved faster in the earlier life of the universe, it may still be moving at different speeds elsewhere today. In telling the story of this heresy, and its gradual journey towards acceptance, Joao Magueijo writes as one of the three central figures in the story, introducing the reader to modern cosmology, to the implications of VSL (variable speed of light) and to the world of physicists. The initial rejection of Magueijo's ideas is beginning to give way to a reluctant acceptance that the young men may have a point - only the next few years will tell the final fate of this 'dangerous' idea.
