I just realised, Marvel have really read into Greek Mythology. I mean, they’ve made sure that they’ve got the details right. Because at the start of Thor it does this camera shot thing where it’s on Earth and then it goes underwater and it looks like it goes back up to Earth but- it’s Asgard. Actually, thinking about it, they didn’t really have to read into it. But still, I credit them.
I think you mean Norse Mythology. Thor is in the Norse pantheon. But you are right in the sense that they kept the Norse cosmology fairly accurate. In Norse myth, Asgard is connected to other worlds through a rainbow bridge.
