Faster Than Light

Faster Than Light PDF 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

A Philosophical Rejection of the Big Bang Theory

A Philosophical Rejection of the Big Bang Theory PDF Author: Khuram Rafique
Publisher: Createspace Independent Publishing Platform
ISBN: 9781986907378
Category :
Languages : en
Pages : 68

Book Description
Scientific inquiry takes onward course from the point where previous scientists had reached. But philosophical analysis initiates from scratch. Philosophy questions everything and chooses starting point for itself after having ruled out all the unsubstantiated and doubtful elements of the topic under study. Secondly, known realities must make sense. If a theory is officially 'counter intuitive', then either it is mere fiction or at the most; a distorted form of truth. This book's analysis is based on the philosophical principle that knowledge is empirical and does not arise magically in absence of observational grounds. With philosophical approach, it was doubtful to accept that Georges Lemaître already knew Hubble's law in year 1927 that was yet to be found by Edwin Hubble in year 1929. Therefore this book started with denial of the claim that Lemaître already knew this law. But analysis of section I.III forced author to look the matter from original source and it came to surface that Lemaître knew this law in year 1927. But contrary to mainstream claim, Lemaître had not derived that law from general relativity (GR) equations rather had deduced from a method given by Hubble himself. Whereas whole case of the Big Bang Theory rests on misleading claim that Lemaître had derived this law solely from GR equations. The basis of this claim happened to be a manipulated translation (1931) of Lemaître's original 1927 article. People regard Big Bang Theory as truth because authoritative sources deceived them by presenting a manipulated translation in year 1931. This book is a philosophical analysis of original papers of Alexander Friedmann (1922), Georges Lemaître (1927), Edwin Hubble (1929) and Albert Einstein (1917) thus covers actual roots and origins of the Big Bang Model. In this book, only the core elements of the Big Bang Model i.e. 'Expansion of Universe' and 'CMBR' are covered. It has been sufficiently shown that 'expansion' is an illusion whereas CMBR is a proof that we live in a non-expanding infinite universe. If these two core elements of the standard Big Bang Model are precisely refuted then there is nothing crucial left with the standard model. For readers of this book at least, Big Bang Theory shall become a story of past mistakes. Author is not an authoritative source on science topics therefore readers must download all the above mentioned original papers and check all the points outlined in this book from relevant original papers. Unlike reading from an authoritative source that makes readers relaxed and careless but enables authorities to deceive them in worst way possible, this book requires readers to remain alert on all the points discussed in the book and verify everything from original sources whose links are given at the end of this description and also provided in footnotes section of the book. This book is not a judgment of the topic rather it is like a case presented by an advocate while readers are the judges. Readers are required to apply their own critical judgment to conclude the matter by themselves. After carefully reading this book, readers will also start taking 'authoritative sources' with due care and it will become difficult for the 'authorities' to deceive them again.

The Dark Physics of The Universe

The Dark Physics of The Universe PDF Author: Burtay Mutlu
Publisher: Burtay Mutlu
ISBN: 1645704440
Category : Philosophy
Languages : en
Pages : 164

Book Description
This book uses the knowledge of physics to interpret the events and facts in the Universe from a completely different perspective as philosophically. In a way, this is a philosophy for physic with a different Universe model proposal. It proposes some answers for the mechanism of motion in the perspective of Speed, momentum, relativistic mass, mass existence, inertia, time dilation, length contraction by using Waveform Time due to expansion of the Universe. In this view, you can see the mechanism of time dilation and length contraction in the quantum level under constant speed and acceleration. The book also suggests some explanations for The Time, The Dimension, the 4th and 5th dimensions, The Anti Matter, The Spin, The Bonds, The Chaotic Systems. And the Book gives some answers in the same viewpoint for the impossibility of traveling in Time and reaching Light Speed for the Mass.

The Fabric of the Cosmos

The Fabric of the Cosmos PDF Author: Brian Greene
Publisher: Vintage
ISBN: 0307428532
Category : Science
Languages : en
Pages : 594

Book Description
NATIONAL BESTSELLER • From one of the world’s leading physicists and author of the Pulitzer Prize finalist The Elegant Universe, comes “an astonishing ride” through the universe (The New York Times) that makes us look at reality in a completely different way. Space and time form the very fabric of the cosmos. Yet they remain among the most mysterious of concepts. Is space an entity? Why does time have a direction? Could the universe exist without space and time? Can we travel to the past? Greene has set himself a daunting task: to explain non-intuitive, mathematical concepts like String Theory, the Heisenberg Uncertainty Principle, and Inflationary Cosmology with analogies drawn from common experience. From Newton’s unchanging realm in which space and time are absolute, to Einstein’s fluid conception of spacetime, to quantum mechanics’ entangled arena where vastly distant objects can instantaneously coordinate their behavior, Greene takes us all, regardless of our scientific backgrounds, on an irresistible and revelatory journey to the new layers of reality that modern physics has discovered lying just beneath the surface of our everyday world.
