A universe, also known as a dimension was a large location that held many galaxies, stars and planets. There were three major universes that existed in conjunction with each other through the multiverse known as Earth-9471, Earth-167 and Earth-1218. The realm of Azarath was not considered to be a universe.
Any alternate reality could be traveled between through cosmic wormholes, which could be rarely created naturally or artificially opened by devices such as Mjolnir. Rarely, Chelsea Carter — as Raven — could travel through alternate dimensions with her powers.
