Law of Cosmological Intersection

The Law of Cosmological Intersection is a very useful law in the Pencilcosmos. It states that:

In order to change a thing's dimensionality, travel up verses from a structure with differing spatial dimensions, or travel at infinite speeds, an object with one more spatial dimension must intersect with the structure as well as the verse with higher dimensionality, in which things inside the lower-dimensional structure can travel relative to the higher-dimensional object, escaping their verse as well as changing their dimensionality.

(see the Pencilsupremacy article for different phrasing if you need it)

Countless civilizations and entities have utilized this law to escape their home verse, although it is generally considered very hard to travel two dimensional layers above your starting point, as once you have escaped one layer you will have become infinitely small (relative to the outside verse).

This law also holds even if the steps are done backwards (making your dimensionality lower by moving "down" an intersecting object that is intersecting with a lower dimensional verse).

Discovery
The Law of Cosmological Intersection first discovery was most likely in the 1st Era, when an Awefian accidentally used the law to travel down into The Enormous. The Awefian was rescued later, and in a couple LPT, the Awefians had utilized the law to populate The Enormous and fully control it.
