The Emergence of Reality: A Path Integral Interpretation of the Many Unreal Worlds

Bhushan Bhoja Poojary

Abstract

The standard interpretations of quantum mechanics, particularly the Copenhagen and Many-Worlds (MWI) views, fail to provide a satisfactory, physically localized mechanism for wave function collapse or the appearance of a single classical reality. This paper proposes the Emergent Universe from Many Unreal World Interpretation (MUWI), a novel framework that integrates concepts from the Feynman Path Integral Formulation (PIF), the Holographic Principle, and the concept of quantized spacetime. MUWI posits that reality emerges from a finite, pre-existent set of Unreal Spacetime Fabrics, each corresponding to a potential quantum state, or "address." We establish a formal equivalence between these unreal fabrics and the "sum over histories" in the Path Integral Formulation (PIF). The particle’s quantum state is the propagator, calculated as the collective interference of all potential states (shadows) across these fabrics. The critical distinction lies in the collapse mechanism: Measurement is not a branching event, but an irreversible, informational event-an "address change"-triggered by the interaction of a true particle with a shadow. This interaction enforces a new boundary condition, instantaneously collapsing the PIF to a single history (the observed outcome) and transferring the particle's quantum information across a non-local holographic plane. This approach proposes a localized, geometric mechanism for wave function collapse, offers a consistent explanation for the paradox of retrocausality in delayed-choice experiments, and suggests a fundamental link between the quantum wave and the emergent geometry of spacetime.

Emergent Universe from Many Unreal World Interpretation

Bhushan Bhoja Poojary

There are multiple interpretations of quantum mechanics, 2 most famous interpretations are Copenhagen interpretation and many world interpretations. Copenhagen interpretation fails to explain the mechanism behind wave function collapse and many world interpretations avoid collapse by adding infinite branching worlds. Goal of this paper is to provide alternate interpretations which explains mechanism behind collapse using finite pre-existent unreal worlds. All quantum weirdness can be narrowed down to few postulates, if we consider every particle has a dedicated address in event horizon, every address has its own dedicated spacetime fabric, particles will have its projected shadows on other space time fabric and whenever there is interaction between true particle and other shadow particle, new address is assigned for both interacting particles and instantaneously all projected shadow becomes void. We perceive universe from collapse perspective only when particles collapse and new address are assigned, thus giving an illusion that we live in one universe but its result of interaction of multiple worlds. From new postulates we were able to explain how one of the entangled photons can decides other photons path in Wheeler's delayed choice experiment and thus helps us to removes problematic retro causality speculation to explain the phenomenon observed in this experiment.

The Particle That Exists in Spacetime: A 4D View of the Double-Slit Experiment

Pierre Pienaar

This article presents a conceptual interpretation of the double-slit experiment using Feynman's path integral formulation. Rather than treating a quantum particle as a point-like object following a single trajectory, the particle's propagation is viewed as a distributed structure in 4D spacetime. In the path-integral picture, this structure is represented by a coherent sum over possible paths between emission and detection. From this perspective, the observed interference pattern emerges from the phase relationships between these possible spacetime paths. The article distinguishes between propagation and interaction. Propagation is described as an extended 4D process, while measurement appears as a localized spacetime event within a 3D spatial slice, producing the point-like detections observed in the double-slit experiment. The aim is not to propose a new physical theory or to explain the mechanism of collapse, but to provide an intuitive geometric interpretation of the standard quantum formalism and its relationship between quantum propagation, interference, and localized measurement outcomes. This is a conceptual essay and interpretive synthesis, not a proposal of a new physical theory.

Beyond Wave-Particle Duality: A Two-Plane Model of Quantum Reality

Hamza Leith

We propose a novel interpretation of quantum mechanics based on the hypothesis that quantum entities possess two ontologically distinct components—particle and wave—that couple to spacetime through fundamentally different mechanisms. The particle component interacts with spacetime through conventional local, causal coupling, while the wave component exists on a topological plane structurally linked to spacetime's global geometric properties. This dual-mode coupling framework offers intuitive explanations for wave-particle duality, measurement-induced decoherence, quantum interference, and non-local correlations without invoking wavefunction collapse or observer-dependent reality. We outline the conceptual foundations, discuss how this framework resolves longstanding quantum paradoxes, and propose potential experimental tests.

Multiverse interpretation of quantum mechanics

Raphael Bousso A, Leonard Susskind

We argue that the many worlds of quantum mechanics and the many worlds of the multiverse are the same thing, and that the multiverse is necessary to give exact operational meaning to probabilistic predictions from quantum mechanics. Decoherence---the modern version of wave-function collapse---is subjective in that it depends on the choice of a set of unmonitored degrees of freedom, the environment. In fact decoherence is absent in the complete description of any region larger than the future light cone of a measurement event. However, if one restricts to the causal diamond---the largest region that can be causally probed---then the boundary of the diamond acts as a one-way membrane and thus provides a preferred choice of environment. We argue that the global multiverse is a representation of the many worlds (all possible decoherent causal diamond histories) in a single geometry. We propose that it must be possible in principle to verify quantum-mechanical predictions exactly. This requires not only the existence of exact observables but two additional postulates: a single observer within the Universe can access infinitely many identical experiments; and the outcome of each experiment must be completely definite. In causal diamonds with a finite surface area, holographic entropy bounds imply that no exact observables exist, and both postulates fail: experiments cannot be repeated infinitely many times; and decoherence is not completely irreversible, so outcomes are not definite. We argue that our postulates can be satisfied in hats (supersymmetric multiverse regions with vanishing cosmological constant). We propose a complementarity principle that relates the approximate observables associated with finite causal diamonds to exact observables in the hat.

Internal Time Orientation in Double-Slit and Delayed-Choice Experiments

Brett Farkas

This work presents a unified, interpretive account of quantum interference and delayed-choice experiments that applies equally to photons and massive particles. Rather than invoking spacetime trajectories, wave–particle duality, retrocausality, or collapse postulates, the paper locates quantum interference in the coherent evolution of internal, pre-geometric degrees of freedom defined over classical spacetime. Within this framework, “which-path” questions are not merely unanswered but fundamentally ill-posed: interference arises from global coherence of an internal field subject to experimental boundary conditions, while spacetime itself remains single-valued and classical at laboratory scales. The approach reproduces all standard quantum-mechanical predictions without modification and is explicitly interpretive rather than predictive. A central result is a unified explanation of why interference occurs across disparate physical systems—photons, electrons, atoms, and molecules—while decoherence manifests through system-dependent physical mechanisms. Photons and massive particles differ in how internal coherence is lost (e.g., electromagnetic absorption versus collisional and thermal interactions), but not in the underlying principle. Delayed-choice experiments are reinterpreted without paradox: changes to the apparatus modify boundary conditions for the internal field rather than retroactively altering particle histories. By removing spacetime paths from the fundamental ontology, the framework offers a consistent, path-free account of interference, decoherence, and localized detection that preserves the empirical success of quantum mechanics while clarifying its conceptual foundations.

One World, One Reality, and the Everett Relaltive State Interpretation of Quantum Mechanics

Paul L. Csonka

We modify the Relative State Interpretation (RSI) of Quantum Mechanics so that it does not imply many worlds and parallel realities. We drop the assumption that probability amplitudes correspond one-to-one with reality: Not all information is contained in amplitudes, and not all amplitudes need be realized. Amplitudes do not "collapse" after a measurement, but evolve continuously, including unrealized ones. After each "event" only one possible outcome is realized. Therefore, if a value is measured, that value is real, all others are not; there is only one reality and one world. Reality content is "quantized" : unity for realized outcomes, zero for all others. It is "conserved": can move along any possible sequence of events, but only one at a time. The modified RSI is is strictly deterministic in the sense that the "global" probability amplitudes of the universe are determined for all times by the laws of physics and the initial conditions. They guide all events. But it is not deterministic in the sense that from the amplitudes one can not predict which outcome actually happens; that represents new information that accumulates as history unfolds. To the extent that information is part of the physical world, the coming into being of the universe is ongoing, even after the Big Bang. All predictions of the two versions agree, except possibly in esoteric, untested cases.
