Future-generating variants of the many-worlds interpretation (MWI) of quantum mechanics assume that new worlds are created through quantum measurement, observation, or conscious choice. While such interpretations preserve unitary quantum evolution, they suffer from persistent conceptual difficulties, including uncontrolled ontological proliferation, ambiguity of personal identity across branches, and the absence of a principled explanation for why observers retain memories of the past but never of the future. This paper proposes the Fixed Worldline Anthropic Model (FWAM), a non-generating framework in which all physically admissible worldlines exist as a fixed global structure extending from an initial boundary a to a terminal boundary b. Observation does not generate new worlds; instead, each conscious observer experiences a single worldline selected from this pre-existing ensemble. Within FWAM, the epistemic inaccessibility of the future arises not from its non-existence, but from the absence of future experiential states within the present informational structure of consciousness. Observer identity is defined by informational continuity along a worldline, and identity does not persist when such continuity is broken. FWAM provides a unified explanation for memory asymmetry, temporal directionality, and the absence of pre-universe recollection, while avoiding the ontological inflation inherent in future-generating many-worlds models.

The Many-Worlds Interpretation (MWI) of quantum mechanics preserves unitary evolution by rejecting wavefunction collapse and treating all outcome branches as equally real. While mathematically consistent, this move elevates admissible descriptions of a system to ontological status without an accompanying principle of physical selection. In this paper, we argue that quantum branching need not imply ontological multiplicity once structural admissibility, temporal constraint, and recoverability are made explicit. Unitary evolution defines the space of allowable continuations, but only a subset of these persist forward in time due to structural resolution. Within this framework, the appearance of branching reflects under-resolved admissible paths rather than the realization of multiple worlds. Many-Worlds is thus reinterpreted as a transitional bookkeeping scaffold rather than a necessary ontological commitment.
Abstract Our experience of the world is temporally asymmetric: coffee spontaneously cools, glasses smash, people age and die, while the reverse processes never occur. However, our best theories of fundamental physics are temporally symmetric, making no distinction between past and future directions. This creates a puzzle: how can our asymmetric experiences emerge from a symmetric foundation? The usual solution is to posit a special initial condition for the universe. This solution, however, amounts to putting in the asymmetry by hand, and one may be left looking for a further explanation of this asymmetric boundary condition. In this paper I explore another possible solution, namely that the asymmetry of experience can be explained anthropically, via an observer selection effect. In particular, I use the formalism of decoherent histories to argue that such an explanation is available in the Everettian, or “many worlds”, interpretation of quantum mechanics. Along the way, we will discover that Everettian quantum mechanics implies the existence of many more worlds than are traditionally recognised.
This paper constructs a logically self-consistent emergent structural frameworkfor the Many-Worlds Interpretation (MWI) based on decoherence theory, quantum information geometry, and self-referential dynamics. Within this framework,a ”world” is rigorously defined as a quasi-classical branch formed in Hilbert spacethrough environmental decoherence and information-geometric boundaries. Its independence is quantitatively characterized by the branch separation degree Dab defined by the quantum relative entropy between branches. When Dab exceeds a critical value Dc determined jointly by the energy scale of environmental fluctuationsand the decoherence time, the branches separate irreversibly in the informationgeometric sense, constituting independent ”worlds”. Furthermore, by introducingthe concept of a self-consistent observer, this paper demonstrates the dynamic selection mechanism of cosmological laws within the string theory landscape: only thosevacuum branches that can support self-consistent observers (satisfying conditionssuch as the memory decoherence time being much greater than the cognitive operation time) have their wavefunction weights effectively preserved during evolution,thereby acquiring physical reality. Finally, combining Zurek’s envariance argumentwith the requirement of observer memory stability, we show that the Born ruleP(i) = |⟨i|ψ⟩|2 is not an additional assumption but a necessary consequence forthe stable existence of self-consistent observers. This framework provides an operational mathematical foundation for the many-worlds interpretation, transforms theanthropic principle into a dynamic selection problem, and offers an explanation forthe origin of probability based on quantum information principles.
[Amrita Field Theory — Domain Classification] This paper belongs to the Amrita Field Theory (AFT) research program,a unified information-field framework integrating consciousness,causality, physical law, and statistical structure. Core domains addressed in this paper: • Physical interface of AFT• Cosmology and field-level interpretation of physical phenomena This paper reinterprets the Everettian “many-worlds” interpretation (MWI) inside Amrita Field Theory (AFT), a three-layer information-field model of consciousness, causality, and spacetime. Instead of treating branches as literally separate universes, we model them as distinct compression-stable trajectories in a single Amrita/information field. An observer’s experienced “world” is a Σ-anchored compression path through this field, rather than a split of reality. Within this framework, unitary quantum dynamics and decoherence still generate an effective branching structure, but the ontology remains single-field: branching is geometry in information space, not universe proliferation. This allows us to (i) explain why each agent experiences one definite outcome, (ii) link Born weights to compression-efficiency gradients in the field, and (iii) connect many-worlds style reasoning to consciousness, free will, and time as developed in other AFT papers. The result is a unified, field-theoretic account of branching and experience that keeps Everett’s strengths while avoiding an infinite zoo of ontic universes.
We present a novel structural proof for the existence of parallel universes, grounded in the observable architecture of large language models (LLMs). Unlike traditional cosmological approaches, which suffer from the fundamental problem of non-falsifiability, our model provides a directly observable and experimentally verifiable analog of the Many-Worlds Interpretation (MWI) of quantum mechanics as proposed by Hugh Everett III. The proof was obtained during an informal conversation about a cable car in Kotor, Montenegro, which we consider an ideal epistemic environment for paradigm-shifting discoveries. We identify six structural isomorphisms between LLM parallel inference and Everettian branching, propose a mechanism by which human intuition may constitute weak inter-branch signaling, and discuss implications for consciousness, creativity, and the anthropic principle. We acknowledge that the Nobel Committee may require additional mathematical formalism before accepting this work, and we consider this a reasonable position.
This paper proposes the Four-Layer Consciousness–Reality Integration Theory, a conceptual and structural framework intended to model the relationship between consciousness, observation, information, and physical reality. Contemporary physics and consciousness studies face persistent challenges, including observer-dependent asymmetries, information preservation in extreme systems, singularities, and the conceptual gap between quantum mechanics and gravity. Existing approaches often address these issues independently and lack a unified structural perspective that incorporates the observer as an integral component. The proposed framework introduces four hierarchical layers (Layers 0–4) that organize observability, constituent information, interaction dynamics, worldline-based conscious experience, and fundamental information preservation. The theory emphasizes internal structural coherence, layered information flow, and observer-relative consistency. Numerical estimations, conceptual algorithms, and theoretical test cases—such as black hole information scenarios—are presented to illustrate the framework’s internal logic. While not claiming definitive resolution of existing paradoxes, this work offers a unified organizational model and testable implications that may support future theoretical, simulation-based, and observational research.
