Phew, I feel better now. Non-physical scalar and tensor fields permeating all of expanding spacetime in a non-physical manner give rise to physical behavior via local nonphysical wavefunction collapse that we call excitations.
- criddell 2y agoThat's why the mathematical universe hypothesis (everything is built from mathematical structures) seems likely to me.
- halyconWays 2y agoIt's sort of unsatisfying to say that math has the ability to experience itself, though
- criddell 2y agoIs it? That’s basically what a conscious AI would be and I have a hard time coming up with reasons why a software brain couldn’t replace a biological brain.
- TheOtherHobbes 2y agoIt seems incredibly unlikely to me. It's more likely all physics is argument by analogy from limited human experiences, and math is just a culturally consistent subset of that. What look like genius predictions are mostly (Einstein aside...) generations of post docs throwing equations at their whiteboards to see what sticks. A few happen to be confirmed by experiment. Most are quietly forgotten. I strongly suspect we literally can't begin to imagine what's really going on.
