Wave-Based Reality Selection System via Coupled Modified Schrodinger Equations (Total Wave MSE)

Resumen de: US20260311013A1

0000 The invention introduces a Total Wave structure of the Modified Schrödinger Equation (MSE) that deterministically governs quantum collapse using co-evolving field-specific wave-functions. Unlike conventional quantum mechanics, which treats wavefunction collapse as a postulated or probabilistic phenomenon, this invention models collapse as a structured outcome of wave interference from multiple physical fields—electromagnetic, gravitational, strong nuclear, and weak nuclear—each governed by its own nonlinear MSE. 0000 The system wavefunction Ψ

evolves under the influence of these field-specific observer waves Ψ, and collapse occurs when the total interference term exceeds a defined threshold. This model supports not only collapse but also resonance (sub-threshold wave alignment) and non-collapse (persistent superposition), forming a tri-state mechanism of existence. The Total Wave MSE formalism applies to quantum hardware design, computation, sensing, and AI-guided control. By treating collapse as an engineered interference event, the invention enables deterministic reality selection across multiple domains. It extends the scope of earlier MSE patents and proposes that this structure represents a scalable, tunable, and physically grounded Theory of Everything (TOE).

This optimized prompt enhances the reasoning capabilities of large language models by effectively modeling multi-factor dependencies and interactions.
