Hey all - just recently got GoT S1 on BluRay - missed it on HBO but am now following it religiously and have started reading the books. One of the things that strikes me about this world is the peculiar seasonal patterns, with years-long summers and winters. Now, I may be projecting a more science-fiction-y slant on something that is more likely of pure magic or some other supernatural cause, but the intro in particular seems to have the world placed in what could be described as a Dyson Sphere/Shell. Things in favor of the theory: - The intro surface is represented as being concave. - The sun seems to be drifting about over the surface of the shell (or the shell drifting around the sun) - potentially explaining the odd shift of seasons for long periods of time. - Apparently, in later books which I have not read yet, there are references to lost ancient technologies. - While not evidence in favor, there could be some device or series of devices orbiting around the star to periodically block light, simulating night/day. Things against the theory: - The whole intro may be simply nothing more than a stylized and artistic tool for presenting the world to the viewer and prepping them for the places they will visit in any given episode (the cities shown change from week to week). - The presence of stars & constellations. - The existence of the "Sunset Sea" to the west of Westeros. Suns in Dyson Spheres never set - at least, not in the conventional way. A paragraph in this article: http://www.artofthetitle.com/2011/05/12/game-of-thrones/ piques my interest in particular, but there doesn't seem to be much official info about why this is. Other possible explanations for the weird seasons might include: - Variable output/unstable primary star - Highly eccentric and/or elliptical orbit I know it's probably a moot point, but I still think it's fun to wonder about such things, to see if there's a greater meaning behind it all. Has any one had thoughts on this?
