355 | Solo: Looking Quantum Mechanics in the Eyeball

Quantum mechanics, specifically the Everettian interpretation, posits that fundamental reality is a vector in Hilbert space, rendering traditional notions of position and momentum as mere coordinate choices rather than inherent properties. The central challenge lies in the "problem of structure": reverse-engineering how to carve this abstract Hilbert space into meaningful subsystems—such as objects or spatial regions—without relying on pre-existing spatial assumptions. Locality in quantum field theory and the system-environment entanglement known as decoherence offer potential mechanisms for this emergence. While the Wheeler-DeWitt equation in quantum gravity introduces a "problem of time" that complicates dynamic evolution, the ongoing research program of quantum mereology seeks to derive the manifest image of the world from this austere, bare-bones formalism, treating space and locality as emergent patterns rather than fundamental building blocks.
