Time Travel in Einstein's Universe: The Physical Possibilities of Travel Through Time Book

No book is without its charm although this one comes pretty close. Granted, diehard and gullible enthusiasts of space travel no doubt think differently but for the more skeptical they will find little worthwhile here except a gift for explaining the theory of relativity--both special and general relativity--with clarity and simplicity that few can and thus the latter part of the fourth chapter makes the book worthy of the purchase. For those seeking a book that will advocate the resumption of space travel to secure the longevity of the human race as this one does in the last chapter it can be imagined that more thoughtful explanations of the benefits of such exploration are to be found. Likewise, those who want to believe that time travel has any realistic basis will be sorely disappointed. Instead, one will find competitive Gott, cape crusader with his friend Li Xin Li (the former you can, to use an epithet, call batman and the latter Robin) writing a book to lay claim of some very speculative theories. There is one in which Gott, so eager to be the next Newton of time travel, deals with orbiting two cosmic strings that will lead one to the past--Gott himself wants full acclaim as the inventor of this idea. The other, his magnum opus which he shares with his counterpart Robin is figuring out the fact that there will be no explosion if one quickly accelerates in and out of the doors of Misner space, and thus one is now free to leap into time with this. Well I am busy today but I will definitely do it tomorrow. Oh yes, the cape crusaders shook hands with each other in their zeal at finding this an achievable goal. You can learn about their flourishing relationship in the content of this book. Yes the book does explore half a dozen other ways to go into the future and past such as the plausibility of engineering wormholes but frankly it is not worth ones time. The reality is that talk of time travel is an absurdity for a world that has done little that is remarkable beyond flight travel to the moon. We are in the stone ages and yet astrophysists are making mathematical formulas of scenarios that will be implausible even hundreds of years into the future at best and seeking acclaim for it. It has little sense.
