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

Authors:

  • Addresses the physics and mechanics of time travel and faster-than-light motion, compiled by an acknowledged expert
  • Readers uninterested in rigorous proofs can safely skip most of the mathematics but still understand the conceptual issues
  • The bibliography is organized so that the book can be used -to some extent- as a review
  • Proves all statements that cannot be found in well-established textbooks

Part of the book series: Fundamental Theories of Physics (FTPH, volume 193)

About this book

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?
