This paper explores the Many-Worlds Interpretation (MWI) of quantum mechanics as a conceptual framework for understanding fragmentation, uncertainty, and narrative divergence in global economic dynamics. We argue that the logic of Everettian branching –originally introduced to resolve the quantum measurement problem– offers a compelling metaphor for interpreting the proliferation of economic expectations, speculative bubbles, policy contradictions, and systemic crises in a multilateral, post-truth financial world. Situating our analysis within the emerging discourse of narrative economics and cognitive fragmentation, we draw parallels between physical decoherence and economic disconnection, highlighting how modern financial systems increasingly resemble a multiverse of incompatible but coexisting belief structures. We propose that modular tensor categories may eventually offer more refined topological frameworks for modeling such multiplicity. The paper con cludes by outlining ethical and policy implications for re-coherence and the role of observers in navigating global economic multiplicity.

This paper explores the quantum many-worlds interpretation (MWI) and its implications beyond fundamental physics, extending to decision theory, game theory, and economics. Starting from the foundational principles of MWI, we examine how observers interact with branching universes, analyze Newcomb’s paradox in both classical and quantum forms, and discuss applications in quantum game theory and quantum economics. By integrating quantum concepts like superposition, entanglement, and interference, we demonstrate how these ideas resolve classical paradoxes and offer novel frameworks for modeling complex systems. Mathematical formulations are presented using Unicode symbols for clarity. The many-worlds interpretation of quantum mechanics, proposed by Hugh Everett III in 1957, posits that the universe branches into multiple parallel realities during quantum measurements, avoiding the wave function collapse postulate. This framework has profound philosophical and practical implications, particularly in understanding decision-making under uncertainty. In this paper, we synthesize discussions on MWI, observer roles in branching, Newcomb’s paradox, its quantum variant, quantum game theory, and quantum economics. These topics form a coherent progression from quantum foundations to applied interdisciplinary fields, highlighting how quantum principles can reshape classical theories.
The Many-Worlds Interpretation (MWI) of quantum mechanics, first proposed by Hugh Everett in 1957, posits that all possible outcomes of a quantum measurement are realized in coexisting branches of the universe. While traditionally confined to microscopic physical systems, this article proposes that the logic of MWI offers an illuminating metaphor –and potentially a modeling framework– for understanding the increasingly fragmented landscape of contemporary geopolitics. In particular, the behavior and communication strategy of political figures such as Donald J. Trump appear to resonate with an Everettian logic: the simultaneous activation of multiple, incompatible narratives, none of which collapses under scrutiny, and each sustained within separate cognitive or media ecosystems. We argue that this “Many-Worlds political style” challenges classical models of political rationality, narrative coherence, and public truth. Drawing from recent work in quantum cognition, narrative theory, and political psychology, we explore how Everett’s interpretation may offer not only a metaphorical but a structurally meaningful way to describe the emerging post-truth political order. The article concludes with a discussion of how such cross-disciplinary frameworks may contribute to both political theory and foundational questions in quantum epistemology.
The nature of branching in the many-worlds interpretation (MWI) of quantum mechanics remains an open question, particularly regarding its locality and compatibility with special relativity. This paper challenges the conventional view that branching is either global or local, demonstrating instead that it is nonlocal for entangled systems. Through a new analysis of the EPR-Bohm experiment, I argue that global branching has several potential issues and can hardly be justified. At the same time, I argue that branching cannot be entirely local, as entangled particles exhibit simultaneous, spacelike-separated branching, manifesting an apparent action at a distance within individual worlds. However, while nonlocal branching suggests the emergence of a preferred Lorentz frame within each world, the multiverse as a whole retains full Lorentz invariance, ensuring no superluminal signaling. By refining the ontology of branching and resolving tensions between MWI and relativistic constraints, this analysis may help advance our understanding of quantum nonlocality and also strengthen MWI's standing as a viable interpretation of quantum mechanics.
The many-worlds interpretation holds an important position in foundationalstudies of quantum mechanics due to its ontological parsimony—adhering to theuniversality of the wave function and unitary evolution. However, this interpretation has long faced core challenges such as the fuzzy mathematical definition of”world branches” and the origin of probability. Within the framework of a ”faileduniverse,” this paper re-examines the generation conditions and existence formsof many-worlds structure. By introducing topological constraint phase transitionsand self-referential reconstruction dynamics, we prove that when the universe is in a”failed phase” caused by insufficient logical depth, the global many-worlds description collapses, but its topological order parameter—the second Chern number—localizes in a modularized discrete form within causal fragments. The many-worldsdo not disappear but exist in a fragmented, modalized manner; the quantum measurement process is reconstructed in this picture as a topological transition of theobserver on the boundaries of causal fragments, rather than instantaneous wavefunction collapse or global world splitting. This framework unifies quantum measurement, spacetime emergence, and cosmological observations into a self-consistenttheoretical system, and derives three experimentally distinguishable predictions:non-Gaussianity of the cosmic microwave background radiation, the logical noisespectrum of primordial gravitational waves, and a detectable discrete chiral currentin mesoscopic circuits.
The Many-worlds Interpretation (MWI) of quantum mechanics has captivated physicists and philosophers alike since its inception in the mid-20th century. This paper explores the historical roots, evolution, and implications of the MWI within the context of quantum theory. Beginning with an overview of early developments in quantum mechanics and the emergence of foundational interpretations, we delve into the origins of the MWI through the groundbreaking work of physicist Hugh Everett III. Everett's doctoral thesis proposed a radical solution to the measurement problem, positing the existence of multiple branching universes to account for quantum phenomenon. We trace the evolution of the MWI, examining its refinement and elaboration by subsequent physicists such as John Wheeler. Furthermore, we discuss the MWI's impact on contemporary physics, including its connections to quantum information theory and ongoing experimental tests. By providing a comprehensive analysis of the MWI's historical development and current relevance, this paper offers insights into one of the most provocative interpretations of quantum mechanics and its implications for our understanding of the universe.
Abstract This is the world’s first general-audience work to systematically rewrite the underlying logic of economics through quantum thinking. Since Adam Smith, economics has rested on the foundation of Newtonian mechanism: human beings are rational atoms skilled at calculation, resources are scarce stocks with fixed attributes, prices tend toward equilibrium, and markets clear automatically. Yet the rise of behavioral economics shattered the myth of homo economicus, and the 2008 financial crisis, platform economies, free goods, asset-price bubbles, and the repeated tug-of-war between inflation and expectations have again and again exposed the limits of the classical framework’s explanatory power. The problem is not that a particular conclusion needs patching; it is that the entire worldview needs updating. This book argues that what quantum mechanics contributes to economics is not a set of fashionable metaphors, but a rigorous intellectual structure for handling multiple coexisting possibilities, observation that participates in generation, relations that precede entities, and a whole that is greater than the sum of its parts. From this perspective, resources are probability clouds of possibility waiting to be activated by cognition, and scarcity is the result of observational collapse; human nature is a superposition of the rational and the irrational; decision-making is measurement rather than revelation; supply and demand are mutually entangled, and prices oscillate around coherent states rather than settling at static equilibrium; money is an entangled carrier of trust, and institutions are the coherent emergence of economic systems. The book consists of an introduction and six parts comprising forty-two chapters. Part I accomplishes the worldview leap from Newton to the quantum; Part II reinterprets individual choice and cost; Part III dissects the entanglement mechanism of supply, demand, and price; Part IV examines money, cycles, and market networks; Part V rebuilds the theory of value and welfare; Part VI leads to the emergent landscape of property rights, policy, and institutional civilization. Each chapter follows a “break before build” approach: first dismantling a widely held classical myth, then offering a more explanatory answer within the quantum framework, supplemented by real cases spanning ancient and modern, Chinese and foreign history, thought experiments, comparative charts, and chapter-end key takeaways, discussion questions, and further reading. With masterful and penetrating prose, the author makes cutting-edge theory accessible and compelling. Whether you are a researcher or graduate student in economics, management, finance, or decision science, or a general reader hoping to see through the workings of wealth, markets, and society, this book will change the lenses through which you view the world—afterward, the economic world will never look the same.
