Time travel and Asimov's "Eternals" I was reading Asimov's The End of Eternity over the weekend. The plot: Through time travel, the Eternals have been manipulating history so as to avoid tragic events (wars, etc.) that happened in the pre-manipulation version of history from having happened in the manipulated version. In so doing, they are also destroying humanity's creative potential and delaying the emergence of interstellar travel technology. Humans From The Far Distant Future intervene to remove the Eternals from history. I thought I'd drop a note and recommend the book to anyone into time travel.
