15 DAYS Thor: 'Your ancestors called it magic, and you call it science. Well, I come from a place where they're are one and the same thing...My father explained it to me like this, that your world is one of the Nine Realms of the Cosmos, linked to each other by the branches of Yggdrasil, the Worlds Tree. Now you see it every day without realising. The images glimpsed through...What did you call it? This Hooble telescope...So the Nine Realms...Now there is Midgard, which is Earth. This is Alfheim, Vanaheim, Jotunheim and Asgard. And that's where I come from.'
