I mean the basic fundamentals of logic that underly all science and math. Two electrons plus one electron makes three electrons. The circumference of a circular object equals pi times its diameter. If point X is empty space at time Y, then there cannot be something at point X at time Y. If A always makes B happen and B always makes C happen, then A will always make C happen. These are the basic kinds of logical rules that, I think, must apply in all universes. It is just impossible for them not to be true. Since I believe all possible universes probably exist, then as long as you can create a mathematical model of a universe that follows these kinds of logical rules, that universe must exist somewhere.

Our universe can be thought of as a giant computer doing tons of math all the time to calculate the exact trajectory of every particle through spacetime, except it's not computing anything. It's just following the immutable rules of logic and math. If you have a pile of sand that has 8,705,216 grains of sand in it and you throw 324,112 grains of sand on top of it, there are then 9,029,328 grains of sand in the pile. Unlike me, the universe doesn't need a calculator to figure this out. It just makes itself happen, simply because it cannot logically happen any other way. That's what I mean by logic.
