A MUST-READ for anyone interested in real time travel!
on June 6, 2002
I'm a layman when it comes to science, but I was interested in the theories of the reality of time travel. I tried another book (that will remain nameless) which didn't work at all for me. It was just way over my head. This one's great! It's got all of the same kind of information that the first one had, but Nahin is so much more understandable and gets his points across in a much more organized way.
He's literally writing for the lay person here-- the book is intended for writers who would like write science fiction, but want to be scientifically updated on the scientifically possible realities of time travel (both to the past and to the future), teleportation (through wormholes, bending of the 4 dimensions, etc.), the special and general theories of relativity and more. His premise is that science fiction could get away with anything even 50 years ago, when most people and most scientists thought time travel to be impossible, but nowadays, you have to be scientifically sound if you don't want to be laughed out of the literary world. True Sci-fi readers will know if you're legit or not, so Nahin is educating them.
I'm not a writer, but because of the nature of his premise, the book is extremely clear and thus much more informative than the first one ever was. This book even answers questions that I was high-and-dry on before (after reading the first book I picked up). Some of the math may be over the layman's head (some of it's over mine!) and more than you care to know, but he includes a lot of thought-provoking information about the paradoxes of time travel and explains things in pictures very well. He colors his book with quotes and anecdotes from all kinds of works of science fiction and from scientists in the past to make the book fun (and sometimes humorous!).
It's a must-read for anyone interested in the possibilities of time travel and a must-MUST-read for anyone interested in writing a book on anything scientific.
