Time Machines: Time Travel in Physics, Metaphysics, and Science Fiction

Summary: Man Must Conquer Time!
Review: This book is a good introduction to some of the science fiction and science fact speculations concerning the possibility of time travel. It considers time travel from early science fiction speculations (e.g. H. G. Wells' _Time Machine_) to modern science speculations involving quantum mechanics, faster-than-light tachyons, and wormholes. From the classic speculations involving General Relativity of Kurt Godel and his rotating universe, to the modern speculations of Kip Thorne involving the use of wormholes to travel backwards in time, the science of time travel is made clear to the lay person. Philosophical speculation with regards to the metaphysics of time is dealt with fully. The apparent paradoxes of time travel (backwards in time) (e.g. the "grandfather paradox") are considered and possible resolutions to them are proposed. In the end, the reader is left to decide for himself whether time travel is: 1. possible, and 2. feasible (at whatever level of technological advancement). According to Stephen Hawking, the fact that we haven't been visited by time travelling tourists is evidence against the possibility of backwards in time, time travel. I myself do not believe this to be the case and think that there is some other reason for the apparent absence of time travellers. For those of us who boldly wonder about the possibilities of man's future evolution, future technological progress, and future civilization, the issue of time travel is an unavoidable and a tempting one. If man is to ever conquer the galaxy, he must conquer time first. It must be possible - it will be possible! This book is an appeal to dreamers and speculative philosophers to examine fully the issues, paradoxes, and proposed methods of time travel.

Review: This book is a well put together documentation of the idea of time travel: from fiction to the actual physics equations. I have it beside my Weinberg Cosmology and my Wheeler Gravitation book. If he wrote this way about antigravity, someone might get it to actually work... We need more such books that make the future possible by giving us the facts we need!

Summary: This book is awesome!!!!
Review: This book just proves that there are things out there that we dont know, and that we should be figuring it out. Before reading this book I thought time travel was virtually impossible, but after reading it I knew that there is a way to do this we just need to try and figure out the mysteries. All in all this books is by FAR the greatest book on time travel yet.
