If we do come up with a grand unified theory that spawns the existence of everything that's completely self contained and self describing, and it ends up being something like x + y = z, what does that really explain? Why? It's because x + y = z, that's why! Once we boil it down to that why becomes meaningless. Everything ultimately has the same reason why.

I have a feeling that the deeper we get, the more physics will be based on “magical numbers”. We have already come across some. But yes, it is extraordinary how the most pure and simple physics with numbers from quantum randomness can create something like this. Very weird to me.

And why does it matter if everything has a root cause or not? Whether the universe is ultimately deterministic and computable, or uncomputable, or not deterministic at all?

It is our imagination that gives facts like math equations meaning.

I think why everything but x+y=z would be x+y=z. But why x+y=z would still be open unless it is self referential.
