There is a concept of a 'W' axis, which would exist within Euclidean 4D space. Such an environment would possess 5-dimensional spacetime. One hypothesis proposes our universe to exist within a Euclidean 4D hypervolume, with other universes existing within said hypervolume.

In mathematics, there is no real limit on spatial dimensions; dimensions just add another coordinate value.

Fun fact: The 'W' axis uses the terms "ana" and "kata" for travel, equivalent to "up" and "down," respectively.
