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 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.
The interpretation of quantum mechanics has been disputed ever since the advent of the theory in the 1920’s. Famous are the discussions over long time between Einstein and Bohr. Einstein refused to accept the so‐called Copenhagen interpretation, where the wave function collapses at a measurement and where the outcome of the measurement is essentially accidental (“God does not play dice”). Alternative interpretations have appeared, but the Copenhagen school has dominated the thoughts throughout the decades. One interesting interpretation was formulated in 1957 by Hugh Everett at Princeton, a student of John Wheeler, which abandons the wave‐function collapse. In this model the universe is governed entirely by the Schrödinger equation, which does not allow for any collapse. In Everett’s model after a measurement the wave function is separated into different branches that do not interact. This model was left unnoticed for long time until Bryce DeWitt took it up in 1970 and termed it “Many‐Worlds Interpretation”, a term that in some sense is misleading. Everett’s model is incomplete, and it was later supplemented by the theory of decoherence, which explains how the different branches decouple as a result of the interaction with the environment. This extended model has in recent years gained increased respect, and some believe that it is the only model made available so far that is fully consistent with quantum mechanics. This interpretation can also shed some light on the development of the universe and, in particular, on the so‐called Anthropic principle, which puts human beings at the center of the development.
Aiming at the logical paradoxes and intuitive conflicts in mainstream quantum mechanics interpretations, this paper proposes a novel Dynamic Cosmic Splitting-Merging Hypothesis Driven by Inter-Universe Quantum Entanglement. When a physical event has two or more mutually exclusive possibilities, the universe instantaneously splits into corresponding parallel branches, which maintain global inter-universe quantum entanglement. Conscious observation or subjective final choice acts as the trigger for non-local entanglement synchronization, forcing all branched universes to collapse and merge into a unique macroscopic reality. This hypothesis eliminates the counter-intuitive quantum superposition of the Copenhagen interpretation and the infinite proliferation of parallel universes in the Many-Worlds Interpretation, providing a self-consistent and closed explanation for the double-slit interference experiment, Schrödinger's cat gedankenexperiment, and Wheeler's delayed-choice experiment. A minimal mathematical formalism is constructed to formalize the core physical mechanism.
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.
The modern version of the wave-function collapse in quantum mechanics is based on decoherence and leads to the multiverse interpretation of quantum mechanics. The decoherence causes the universe to develop an emergent branching structure. One can interpret the branching structure either as a tree structure or as parallel different histories. Time is not continuous since there are no measurable continuous in quantum physics. Notion of continuous range of possible values of time is just an idealization. The same goes with the direction of time that is a prior assumption based on the branching structure of the multiverse. The multiverse does not exist in external space nor time since there is nothing more beside it. The observer's mind should be not in a superposition with himself. Because of this, in the Many-minds interpretations it is argued that the distinction between worlds should be made at the level of the individual observer. The human bodies are in a superposition, but the minds have definite states that are never in superposition. All possible lives, personalities that do not violate the laws of physics are facts since they represent a valid history in the multiverse. We are one of this possible personalities. Our choices are defined by our personality explained to us by our mind, our consciousness is the unchangeable part of us. It is nonphysical and it senses the world. It does not interact with the brain in the other way beside it.
The many Worlds Interpretation postulates that the universal wave function exists and never collapses unlike the Copenhagen Interpretation. Instead, all possible outcomes of the measurement are realized in isolated parts of the wave function. These parts create the “worlds”. There must be an infinite number of these worlds due to the probabilistic paradoxes caused by having equally real worlds. On the other hand, each spatial dimension consists of an infinite number of the lower spatial dimension. Meaning an n dimensional world consists of an infinite number of (n-1) dimensional worlds. The universal wave function could be 4 dimensional which would explain why these 3-dimensional worlds are isolated. This claim will be further supported with Schrödinger Equation simulations. The 4-dimensional Schrödinger Equation will present a better fit to the Many Worlds Interpretation than the 3-dimensional Schrödinger Equation since it will provide a solution to the statistical paradoxes posed by the interpretation by postulating an infinite number of worlds.
