The MAX

 The MAX  has no known border, the energy orbiting acts as a gas, thinning out the further one goes. So far, astronomers have only been able to come up with a weak estimate. Hopes are for future technological advancements to be able to define a strict border.

Although, It is still unknown whether there exists a real physical border or not.

Unlike the Everywhere, The MAX is a true fractal structure. The combined strength of the cores of the Everywheres allow for real fractal patterns.

Due to the appearance of The MAX, creatures of equivalent size store The MAXes for entertainment purposes, like humans store lava lamps.
