From the list on time travel that respect the paradoxes.
Who am I?
I am an author of science fiction, as well as nonfiction, a singer/songwriter, and a Professor at Fordham University, and time travel has played a role in all of these endeavors. I’ve written four novels and numerous stories which feature time travel, several songs (for example, “If I Traveled to the Past”), and talk about it in my classes. The opportunity of going back in history and stopping a bad thing has always intrigued me, as has traveling to the future to see how things turn out. The paradoxes that can get in the way of that make thinking and writing and talking and singing about it even more fun.
Paul's book list on time travel that respect the paradoxes
Why did Paul love this book?
If you think about it, communication back in time from the present triggers the same kind of paradoxes as physically traveling to the past. If I send information to the past about which horse will win in what upcoming race, how come I didn’t already know that in the present to begin with? Timescape offers a great, scientifically knowledgeable account about how something like that might play out.
