It’s such a deep mystery why do fundamental entities of the universe (particles, fields, molecules) behave in a way that can be captured into neat little mathematical formulas.

This mystery *strongly* suggests the following..

1/ That if these entities behaved unpredictably, we wouldn’t have existed.

Composite systems like us who can ask questions like these can only be built on fundamental units whose behaviour is simple.

2/ That there may be universes where fundamental entities have unpredictable behaviour which can’t be captured by any formula.

Such universes possibly exist, but no being exists within them that can ask complex questions like this one.

3/ That possibly *all* mathematical structures instantiate a universe.

In only a subset of them, beings like us could exist.

It would be super cool if all such universes are ultimately isomorphic to one another. Just like the number 3 and ||| represent the same abstract concept

4/ If physical theories are modelled by maths because they’re maths, we shouldn’t be surprised at finding unexpected connections in physics (like spacetime being one thing, electromagnetism being one) because we can view the same mathematical object from different angles

5/ Of course, maths=physics can’t be proven. You can’t design an experiment to prove or disprove it.

So it’s a religious belief we have to adopt.

6/ But I’d rather believe that everything possible exists than be forced to accept that our universe is a special one with precise formulas for fundamental entities out of nowhere.
