As stated, the 0th dimension cannot be empty because then it doesn’t exist and cannot be full because then it is not made from something. Switching back and forth between states with a formula is isomorphic to other dimensions in the “Defined Class.”
Gravity can be shown from scratch in my book. If there are two objects in 1-D or 2-D and one walks randomly it finds the other one. The equation of gravity can quickly be developed and without time, even in n dimensions we can solve for at least 4 bodies gravitationally.
Electromagnetism also works out.
The other forces are related. Chemistry in 1-D starts with the simplest orbital, a 1-D sphere. This is an object passing by another object, the simplest of thoughts. Thoughts are made from subsets of the instantaneous soup
