1. A big deal was made about the city of Asgard being made on Earth causing all sorts of universal trouble and supposedly the cause for attacks from both Hela and the World-Eaters. Since Asgard is still on Earth shouldn't that problem still be there or did Odin somehow creating it and still inhabit something there solve it? Or did Odin recreate the entire dimension? Or were the World-Eaters just after the empty dimensional space? Or am I just looking for answers where there are none?
2. Does anybody know the status of the rest of the nine worlds? The World-Eaters supposedly devestated most of them, but we don't have any details. Each was supposedly very large, yet again supposedly many of their inhabitants are now on Earth. Odin closed off the dimension of Asgard so Karnilla apparently cannot go home. Surtur's realm was unmolested due to being too badass to invade. Hela returned to Hel so Nieflheim I assume to be okay. Based on the comments the other realms are inhabited and alright. So why don't all the giants, fairies, and what not just go home?
