Warning: This story contained some mild spoilers from the first six seasons of Game of Thrones.
The world of Game of Thrones may be fictional, but that doesn't stop its fans from heatedly arguing about all the possible underlying science, because nerd-gassing about one's favorite science fiction is a time-honored tradition. Just how hot is dragon's breath? Is there a real-world equivalent of wildfire? What's the best and worst way to die? And how fast would Gendry have to run back to the wall to send a raven to King's Landing requesting help?
These and other scintillating topics are discussed in a forthcoming book by physicist (and uber-fan) Rebecca Thompson, Fire, Ice, and Physics: The Science of Game of Thrones. The book comes out in October from MIT Press, but as we gear up for the premiere of the final season Sunday night, Thompson graciously gave us a sneak preview into some of the burning science questions she investigated.
