Abstract

We develop a framework in which the quantum wavefunction does not represent a particle, but space itself. In this view, the complex amplitude Ψ(x,t) is a field intrinsic to spatial geometry. Matter and radiation are excitations bound to this space-wave; gravity arises as the flow of space toward concentrations of mass-energy; and measurement collapse is a nonlinear geometric phase locking of Ψ into a localized configuration.

We present a Schrödinger-type dynamical equation for Ψ with Laplace–Beltrami kinetic term, curvature coupling, and nonlinear self-interaction. We demonstrate how the Young double-slit experiment emerges naturally as interference of space modes, and estimate gravitational self-energy effects on collapse using the Diósi–Penrose heuristic. We connect this “wave-geometry” program with objective collapse models, canonical quantum gravity, the river model of black holes, and nonlinear Schrödinger analogies. Experimental implications and open problems are discussed.


1. Introduction

The foundational puzzles of physics — quantum measurement, spacetime structure, and gravity — remain unresolved despite a century of progress.

  • Quantum mechanics provides a predictive algorithm but leaves ambiguous the ontological status of the wavefunction. Is Ψ a real physical field, a probability amplitude, or something else?
  • Gravity, in general relativity, is geometry itself: matter tells space how to curve, and space tells matter how to move. Yet this geometric description resists unification with quantum theory.
  • Measurement collapse introduces non-unitary “events” into otherwise deterministic dynamics. The question of how and why remains central.

Existing proposals include objective collapse theories (GRW, CSL, Diósi–Penrose) [Bassi et al. 2013], canonical quantum gravity (Wheeler–DeWitt), and heuristic models such as Painlevé–Gullstrand’s “river model” of black holes.

In this paper we propose a unified reinterpretation: the wavefunction is not a function of particles in space, but a function of space itself. Collapse corresponds to geometric phase locking of this field, and gravity corresponds to the inward flow of space toward dense concentrations.


2. Formalism

2.1 Ontological postulate

Let M be the three-dimensional spatial manifold. Define a complex scalar field:

Ψ : M × R → C.

Interpretation: ρ(x,t) ≡ |Ψ(x,t)|² is the amplitude density of space itself. Excitations of this field are what we perceive as particles and photons.

2.2 Dynamical law

We postulate a nonlinear Schrödinger-type equation:

iħ ∂t Ψ(x,t) = [ – (ħ² / 2μ) Δg + Vcurv(Ψ) + Λ f(|Ψ|²) ] Ψ(x,t). (1)

  • Δg: Laplace–Beltrami operator associated with metric g.
  • μ: effective inertia of space.
  • Vcurv: curvature-coupled potential.
  • Λ f(|Ψ|²): nonlinear collapse-driving term.

Equation (1) is nonlinear and self-consistent.

2.3 Metric coupling

To close the system, |Ψ|² is mapped to curvature. Options:

  1. Scalar curvature ansatz: R(x,t) = κ ρ(x,t).
  2. Metric perturbation ansatz: gij = ηij + α Gij[ρ] + …, where Gij is a Green’s function convolution of ρ.

Thus Ψ determines curvature, which in turn governs Ψ.

2.4 Collapse term

Collapse is modeled as a focusing nonlinearity or stochastic CSL-type term. A simple deterministic choice:

f(ρ) = ρ, with Λ > 0.

This allows attractor-like soliton solutions, representing localized “spots” on measurement.


3. Young’s Double-Slit as Geometry Interference

Consider two slits A and B at separation d. At a screen a distance L away, approximate:

Ψ(x,t) = cA ΦA(x) + cB ΦB(x),

with Φ modes carrying phase terms ~ e^{ikr}/√r.

Projecting Eq. (1) onto this two-mode subspace yields:

iħ d/dt (cA, cB)ᵀ = H₂×₂ (cA, cB)ᵀ,

with Hamiltonian H containing energies EA, EB and coupling K.

The screen intensity is:

I(x) ∝ |ΦA(x) + e^{iΔφ} ΦB(x)|²
= |ΦA|² + |ΦB|² + 2 Re{ΦA ΦB* e^{iΔφ}}.

Thus, interference fringes emerge as geometry-mode interference. Collapse is the transition of Ψ into a localized soliton — the observed “hit.”


4. Worked Example: Gravitational Perturbation from Collapse

Following the Diósi–Penrose heuristic, collapse timescale τ relates to gravitational self-energy EG:

τ ≈ ħ / EG,
with EG ≈ (3 G m_eff²) / (5 R).

Take m_eff = 10⁻¹⁵ kg, R = 10⁻⁶ m:

EG ≈ 4 × 10⁻⁵⁰ J.
τ ≈ 2.6 × 10¹⁵ s ≈ 80 million years.

Thus for microscopic systems collapse is negligible, consistent with coherence. At mesoscopic scales, τ decreases, predicting new physics.


5. Relation to Existing Programs

  • Objective collapse (Diósi, Penrose): Our collapse term aligns with gravitational self-energy heuristics.
  • Wheeler–DeWitt: Ψ(x,t) resembles a reduced wavefunction of 3-geometry. A covariant extension could connect directly.
  • River model of black holes: Gravity as “space flow” is a natural extension here.
  • Nonlinear Schrödinger/Gross–Pitaevskii: Collapse dynamics mirror soliton formation in condensates.

6. Predictions and Tests

  1. Mesoscopic interference: Molecule interferometry should show deviations from standard quantum predictions at masses approaching 10⁻¹⁶ – 10⁻¹⁴ kg.
  2. Local metric fluctuations: Tiny metric perturbations may accompany detection events — potentially observable by ultra-sensitive interferometers.
  3. Quantum-gravity crossovers: Experiments combining superposition with gravitational effects could discriminate this model from standard quantum mechanics.

7. Open Problems

  • Covariant relativistic generalization.
  • Derivation from a deeper pre-geometric substrate.
  • Ensuring Lorentz invariance and causality.
  • Parameter bounds from interferometry and collapse-model constraints.

8. Conclusion

In the wave-geometry picture, quantum amplitudes belong not to particles but to space. Collapse is a geometric phase transition, and gravity is the flow of space itself.

This program unifies strands from objective collapse, canonical quantum gravity, river models, and nonlinear Schrödinger analogies. It yields a concrete PDE framework, rich with mathematical and experimental challenges.

If correct, this reframing suggests that the true universal constant is not the speed of light, but the speed of space.
