I have a question for all the geeks (like myself) that watch Game of thrones. The opening credits of the show depicts a three-dimensional map of the series' fictional world, projected onto a concave earth.
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 slant on something that is more likely of pure magic or some other supernatural cause, but the intro inparticular seems to have the world placed in what could be described as a Dyson Sphere/Shell.
You don't need a dyson sphere to explain long summers and winters, a highly elliptical orbit would suffice.
On Earth, a year is defined as one revolution of the Earth around the Sun. However, we have no idea what the definition of a year is in the world of Westeros. It could simply be defined as a number of days. So one revolution of that planet could conceivably take hundreds of Earth years, and the long winters are periods where the planet is far away from its sun.
