Systematic Stress Testing of Traversable Wormhole Architectures
Year: 2026
Type: preprint
Abstract: This extended preprint presents an archive-grounded retrospective synthesis of a research program containing 35 model labels or major tested architectures for traversable or throat-like spacetimes. The inventory represents a dependent model lineage rather than 35 independent experiments and includes candidate backgrounds, repair attempts, support screens, rotational modules, explicit-action searches, numerical stress tests, and destructive attack calculations. The program began with a fixed open, two-way traversable-throat objective. Successive failures motivated increasingly substantial architectural changes, including black-bounce geometries, nested throats, compact-star embeddings, torque layers, thin-shell and regular-core support mechanisms, beyond-Horndeski action searches, dense-QCD environments, semiclassical source screens, and independent in-project numerical implementations. Across the tested set, no branch both reached and passed every applicable mandatory gate required for a complete-model viability claim. Restricted successes included regular finite-throat geometries, first-order rotational transport, host-induced frame dragging, selected background-level stability results, and dense-QCD host configurations. Terminal failures or unresolved gates included null-energy requirements, ghost or strong-coupling pathologies, characteristic-cone violations, low-frequency perturbative instabilities, background-equation nonclosure, matter-interface inconsistencies, source insufficiency, and failure under dense-grid numerical reproduction. The manuscript does not claim discovery, observation, or successful construction of a physically viable traversable wormhole and does not present the model inventory as a universal no-go theorem. Project-internal audits, preregistration, holdout checks, and separate implementations are explicitly distinguished from external validation. The principal contribution is a documented negative-results and model-falsification record, together with a prospective research protocol that freezes the physical question, throat class, action, host, validation hierarchy, numerical convergence requirements, and independent reproduction criteria before future model optimization. Following retrospective review of the model lineage, the original open-throat program was stopped. A separate closed-throat research direction is identified only as a future program and is not presented as a demonstrated solution.
