Come awwnnnn, Ethan, was this article really necessary? What in the known and unknown universe does it have to do with REALITY? I’m soo sick of articles swooning over every trivial detail of what is in the last analysis JUST A TV SERIES! So George R R Martin put his sf background away when he wrote the books, so WHAT?? It isn’t supposed to be astro-physics, is it? Are we to have a scientific justification for dragons and all the other weird pseudo-Tolkeinian creatures? Howsabout sticking to what’s real from now on? Given the current plague of idiocy and ignorance that’s abroad throughout the land, it’s needed very badly.
