A dimension exists in an universe.

As an example:

The Asgard we all know is a dimension which is part of Earth-616. And there are different versions of Asgard depending the universe, in the Ultimate Universe, every Asgardian god but Thor was killed, in the Marvel Cinematic Universe Asgard is more technological than magical.
