Hard sci-fi novels about time travel and Godel universes

[Benzoate]

anybody know any good "hard " sci-fi novels on time travel? Preferably the kind discussing the philosophical implications of time travel , and/or incorporate Godel Universe and Einstein General theory of relativity into its plot.

Time machines : time travel in physics, metaphysics, and science fiction by Paul Nahin has an extensive discussion of sci-fi books dealing with time travel as well as the philosophical implications (see my review of this book at http://www.chronon.org/Science/Time...physics,_metaphysics,_and_science_fiction.php)

'The Proteus Operation' by James P. Hogan is one of the best that I've ever read.

The "Ender" series of books by Orsen Scott Card are classic SF which incorporate a mostly correct interpretation and use of relativistic time dilation. There is no travel into the past and no faster than light travel.

There are a few science fiction-y unexplained technological leaps regarding instantaneous communication (Impossible according to SR & GR) and the final book in the series, Xenocide, ends with the one of the worst cases of Deus ex machina combined with low-end SF "magic," otherwise Card is very careful with the science, philosophy, and history in his books.
