Watch 'Game of Thrones' mysteries explained (or disproved) with science

Sure, works of fiction are hardly subject to the rules of science, but the folks behind It's OK To Be Smart set out to explain many of the enigmas surrounding Game of Thrones. In the PBS digital short that awaits after the break, topics like the plausibility of Daenerys' dragons, winters that last a decade, the origins of Valyrian steel and more are given real-world significance through the lens of scientific explanation. Also, it's decided that the planet on which Westeros resides should be called Hodor -- an honor of which he's pretty deserving, if you ask me.
