The Earthspace refers to the Earth's universe, this being the specific universe within a reality where the planet Earth is located. It's the plane of existence where the planet shares space and time with other celestial bodies, like the Sun, the rest of the Solar System, the Milky Way, the Andromeda Galaxy, and so on.
- The Earthspace was called such only in the recap page of Avengers Academy #19. In most instances it's only referred to as "our dimension" by its inhabitants without a given name. In Doctor Strange, Sorcerer Supreme #21, for instance, it's only called "Earth's universe."
