Towards a theory of wavefunction collapse Part 2: Collapse as abrupt reconfigurations of wavefunction's evolution in a dynamically expanding spacetime

Garrelt Quandt-Wiese

A new approach to wavefunction collapse is proposed. The so-called Dynamical Spacetime approach enhances semiclassical gravity and enables it for an explanation of wavefunction collapse by postulating that the spacetime region on which quantum fields exist and on which the wavefunction's evolution can be regarded is bounded towards the future by a spacelike hypersurface, which is dynamically expanding towards the future. Collapse is displayed in the way that the wavefunction's evolution becomes unstable at certain critical expansions of spacetime, at which it reconfigures via a self-reinforcing mechanism quasi-abruptly to an evolution resembling a classical trajectory. Thereby, spacetime geometry changes in favour of the winning state, which causes the path of the other state to vanish by destructive interference. This mechanism for collapse can explain the quantum correlations in EPR experiments without coming into conflict with relativity and the Free Will theorem. The Dynamical Spacetime approach is mathematically formulated on basis of the Einstein-Hilbert action and predicts for the Newtonian limit the same lifetimes of superpositions as the gravity-based approaches of Diosi and Penrose. A second important feature of the Dynamical Spacetime approach is its capability to forecast reduction probabilities. It can explain why all experiments performed so-far confirm Born's rule, and predict deviations from it, when solids evolve into three-state superpositions. The basics needed for the derivations in this paper are developed in Part 1 by an analysis of semiclassical gravity.

PEDLER: A Deterministic Event–Hypergraph Foundation for All of Physics

Abhishek Choudhary

PEDLER (Point Event-Driven Learner) is a proposed deterministic event–hypergraph framework for fundamental physics in which physical reality is modeled as a finite, typed, directed hypergraph evolving through local causal rewrite rules. This research poster presents the conceptual foundation of the PEDLER Unified Physics Programme, motivated by unresolved questions surrounding quantum measurement, wavefunction collapse, spacetime, gravity, and cosmology. It introduces the proposed primitive ontology, deterministic event dynamics, causal hypergraph evolution, emergent spacetime, quantum correlations, gauge interactions, black holes, and cosmological evolution within a unified conceptual framework. The poster concludes with an initial collection of foundational axioms, primitive rewrite operators, required emergence theorems, open mathematical problems, and experimentally falsifiable predictions. It is intended as the foundational blueprint for a long-term research programme rather than as a completed physical theory. Mathematical derivations of quantum mechanics, general relativity, gauge theory, particle physics, and cosmology remain objectives of future work requiring rigorous formalization, proof, computational validation, and empirical verification.

Wavefunctions as Low-Dimensional Projections of Strings:A Unified Description of Quantum States, String Amplitudes, and High-Dimensional Boundary Conditions

WUN, SYU JIA

This paper proposes a central thesis: The quantum-mechanical wavefunction ψ(x) is not a description of a particle itself, but a projection of higher-dimensional string amplitudes into 3+1 spacetime. Under this interpretation, quantum superposition, collapse, and nonlocality are no longer independent mysteries but distinct projection behaviors of the same higher-dimensional structure. We show that: Wavefunction superposition corresponds to the linear superposition of string amplitudes. Wavefunction collapse corresponds to selecting and stabilizing a point in the high-dimensional moduli space. Spatial spread of ψ(x) corresponds to the topological extensibility of strings in higher dimensions. Quantum nonlocality is the natural projection of high-dimensional connectedness. The measurement problem becomes: the selection of a projection boundary condition in higher-dimensional space. Because both quantum mechanics and string theory are built on amplitudes and moduli spaces, we unify them by proposing the String–ψ Correspondence: ψ(x)=P[Ψstring​(S)], where ψ(x) is the observed low-dimensional wavefunction and Ψ(S) is the full string-state wavefunction before projection. This unified framework offers new insights for quantum gravity, quantum information, cosmology, and particle physics.
