So, my confession today is that I loved the book "The Time Traveler's Wife." (I have not seen the movie.) I was very afraid to read it because I just knew that at some point, the logic of the main character, Henry, going back and forth in time would unravel, there would be inconsistencies, and I would get mad. But it didn't. The book really held together. I read just yesterday, that my amateur assessment is echoed by a physicist, who says that the book's premise works, based on what physicists believe would be true about time travel.
Just one nugget. I have often heard folks say (and probably echoed myself) that time travel will never be possible; otherwise, people from the future would be here telling us about it. (And yes, I guess they could be undercover or keep it a secret, but that wouldn't last long.) According to Dr. Goldberg, should time-travel ever be made possible, which I guess most physicists don't believe it will, that point in time would mark the beginning of time travel in either direction. You can't go back in time unless there's an "off-ramp" there, as he puts it. Read the whole thing -- and read "The Time Traveler's Wife" in your spare time!
