To those who have seen the new Thor movie, in the Cinematic universe, are the nine realms actually different 'realms' as in dimensions, or simply different planets within a star system they refer to as the worlds tree? Its never really explained one way or the other, especially with Asgard being a flat disc rather than an actual planet, so are they all different planes? Or is it that Earth is the only one of the nine realms which is in our dimension and the rest are not physically in our galaxy (as in you cant travel to them through space, only by teleportation methods like the bifrost or the portals thor 2)?

If not then im assuming they're just a small constellation grouped together, as there are far more galaxies outside of the nine realms, such as wherever Loki ended up when he met Thanos.
