Measurement as Reshaping of Space (and QFT) in the Foam-Plexus Model

The quantum measurement problem in standard physics arises because the wavefunc- tion encodes probabilities spread over space, yet measurements return definite outcomes. In the Foam-Plexus model, this paradox dissolves. Spacetime is a discrete lattice of Planck- scale quanta connected by wormholes, and the electromagnetic (EM) Plexus is the physical shape of space generated by proton–electron fluxes. The electron itself is a jittering tetra- hedral wormhole structure embedded in this geometry. The wavefunction is not an abstract probability amplitude but an eigenmode of the connectivity tensor Cµν , whose eigenmodes correspond in the continuum limit to spherical harmonics. Measurement does not “collapse” the wavefunction: it re-threads the wormhole network, changing the shape of space so that a definite electron position is realized. We formalize the connectivity tensor, derive its per- turbation under measurement, link to the discrete foam Laplacian, and identify testable corrections to hydrogen spectra and precision QED observables. Multi-particle extensions and cosmological implications (e.g., the CMB as early foam measurement) are explored.
