In Norse mythology, I think they were all separate realms (flat earthers), and thats how they were depicted in Norse mythology, on different branches, and between them was the void area (can't remember the name). Marvel writers made most of the connected on one giant landmass, and between them are these other areas such as Nornheim, but that idea has been practically abandoned by current writers since it gets complicated. For example, Nornheim and the Nornkeep was originally shown on the Asgard map, but in Thor #700, the Nornkeep was on the center of the Yggdrasil between the branches Also, yes there are portals between worlds which could be how they got there like how Loki, Thor, and Jane got to Svartalfheim in Dark World.
