The Spherical Physics Page

"Every universe is contained within a 5th, 6th and 7th dimensional sphere.  These spheres move along these (and the 8th dimension, spherical time) while the universes inside of them operate on the 1st, 2nd, 3rd and 4th dimensions (horizontal, vertical, depth, time).   Generally, each sphere contains only one universe.  These spheres move around randomly and occasionally collide.  When this happens, either the spheres will combine to contain two separate universes, or the universes will be scrambled amongst each other, creating a chaotic universe (every universe has different laws of physics, so having two sets of laws in one universe is chaotic).  If a normal, one universe sphere, collides with a sphere containing a chaotic universe, the spheres will implode into an almost infinitely small (it still has size along the 8th dimension, just not the 5th, 6th, or 7th) object called an "Andrick Sphere".  Eventually (along 8th dimensional time), this "Andrick Sphere" will contract into an actual point (with zero volume).  Until it reaches this point, the universes inside will not be affected, because the dimensions that the sphere is
shrinking on are different from those within the universes.  Once the "Andrick Sphere" contracts to a point, there will be a catastrophic explosion as all of the matter in the universes is converted into energy.
 This energy will be contained in the expanded sphere and will eventually cool off into a normal universe.  There will be nothing left of the original two universes.  There is an alternate theory to what eventually happens to an "Andrick Sphere". Some scientists calculate that when it shrinks into a point it will stay that way. Supposedly it will then attract other spheres which will also shrink. This will pretty much destroy the sytem of spheres. Theoretically, the universes cannot escape from the "Andrick Sphere" unless a great amount of energy is forced into the 8th dimensional space between the two universes.  This amount of energy is directly proportional to the amount of matter in each universe multiplied by the inverted amount of 8th dimensional space between them." ¹

The Mushroom Zone is an example of a chaotic universe.  While most universes are composed of planets and flaming stars, The Mushroom Zone is a strange double cone. When the original link was made between The Mushroom Zone and our universe, it drew our sphere and that of The Mushroom Zone closer together.  When the mushrooms built Mushroom Portals, they forged permanent links between the two spheres.  Our spheres were actually connected in an Andrick Sphere!  When the Mushroom Portals were destroyed, the two spheres separated back out because of the huge amount of energy released by the nuclear weapons used to blow up the portals.
