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?Fundamental Theories of Physics,0168-1222 ;193GravitationCosmologyPhilosophy of naturePhysicsClassical and Quantum Gravitation, Relativity Theoryhttps://scigraph.springernature.com/ontologies/product-market-codes/P19070Cosmologyhttps://scigraph.springernature.com/ontologies/product-market-codes/P22049Philosophy of Naturehttps://scigraph.springernature.com/ontologies/product-market-codes/E34040History and Philosophical Foundations of Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P29000Gravitation.Cosmology.Philosophy of nature.Physics.Classical and Quantum Gravitation, Relativity Theory.Cosmology.Philosophy of Nature.History and Philosophical Foundations of Physics.530.1Krasnikov Sergueiauthttp://id.loc.gov/vocabulary/relators/aut833863BOOK9910300551903321Back-in-Time and Faster-than-Light Travel in General Relativity1864324UNINA
