Editorial Review:

Product Description:
Where the science of black holes, gravitational waves, and time travel will likely lead us, as reported by spacetime's most important theoreticians and observers.

Our minds tell us that some things in the universe must be true. The New Physics tells us that they are not, and in the process, blurs the line between science and science fiction. Here are six accessible essays by those who walk that line, moving ever further out in discovering the patterns of nature, aimed at readers who share their fascination with the deepest mysteries of the universe.
• Richard Price: "An Introduction to Spacetime Physics"
• Stephen Hawking: "Chronology Protection"
• Igor Novikov: "Can We Change the Past?"
• Kip S. Thorne: "Speculations about the Future"
• Timothy Ferris: "On the Popularization of Science"
• Alan Lightman: "The Physicist as Novelist"

- The State of Real Time Travel
A series of essays on the concept of Time in current Theoretical Physics. The papers were presented in 2000 following a tradition within the community of Physics. These topics honor Kip Thorne on the occasion of his 60th birthday. Thorne has investigated the possibility of actual time travel in current concept of Spacetime.

Igor Novikov provides arguments for the possibility of travel to the past, but concludes that it is impossible to change the past, which has already happened, including any effects of a future person traveling back into time. Stephen Hawking argues that travel in time, in the science fiction concept, is impossible, likely violating the laws of physics as we understand them now.

- Interesting thinking on the edge of knowledge
This a book derived from 5 physicists who gave a discourse to honor Kip Thorne on his 60th birthday. If you're interested in the musings of some of the greatest minds in science, this is an excellent book. Absent is the mathematics that gives substance to the thoughts, which makes this subject very approachable to the lay audience.

The topics are far ranging in the field of physics and the discussions are beyond the edge of what is currently provable. This is the area of where knowledge meets intuition, where great theories and insight are born.

If time travel, the universe as four dimensions, and related subjects are not for you, then this isn't the book for you. If your interested in the thoughts that will propel further investigation in the quest for knowledge ... Read More

- Is time-travel possible?
-----------------------------------------------------------
This slim volume consists of six essays, based on talks presented at the Kipfest [note 1] on the occasion of Kip Thorne's sixtieth birthday. Thorne, the Feynman Professor of Physics at Caltech is best known to the general public for his 1988 wormhole "time machine" proposal, and indeed much of the book is taken up exploring the question, "is time travel possible?"

Physicist Richard Price leads off with a concise refresher-essay, "Welcome to Spacetime." Danish physicist Igor Novikov explores classic time-travel paradoxes, with some cool diagrams and novel results: in essence, "closed timelike curves" [note 2] are theoretically possible, but paradoxes aren't allowed -- with ...

- Sorry, grandma, I won't be seeing you again anytime soon.
Time travel appears pretty impractical based on this book. Maybe it's mathematically possible to fold time and punch wormholes in it in theory, but I don't think NASA or Greyhound is going to be offering trips back and forth through our lives. However, it's always intriguing to read what really smart people come up with, because they make a lot of it seem so obvious, even though I could never come up with it on my own.

- Garbage
It is incredible how they trust blindly in EVERY aspect of General Relativity. Space-time warpages and singularities happens ONLY in mathematics! There is no way out. It is funny how Scientific American gives credibility to such a kind of science-fiction. It is time to stop lying to the public!

Hawking and Thorne, grasp it: Time-travel is physically IMPOSSIBLE.
