It May Not Be the Great Attractor: The Great White Hole Hypothesis
Zenodo
It May Not Be the Great Attractor: The Great White Hole Hypothesis presents a speculative and falsifiable alternative interpretation of large-scale cosmic motion. Instead of assuming that all observed peculiar velocities arise solely from gravitational attraction toward overdense regions such as the Great Attractor and Shapley Supercluster, the paper explores whether part of this motion could represent accumulated movement away from an ancient, persistent, extremely distant divergent source located broadly opposite the observed flow direction. The proposed Great White Hole Hypothesis (GWHH) is tested through phenomenological modeling, numerical simulations, and comparison with large-scale velocity-field data, including Cosmicflows-4. The results identify directional relationships compatible with a “push-from-behind” geometry, while also showing that standard cosmological structure formation can already explain much of the observed coherent flow. The hypothesis therefore makes a clear observational prediction: it becomes relevant only if a statistically significant divergent residual remains after the velocity field predicted by conventional matter-density distributions is removed. The work does not claim the detection of an astrophysical white hole, but proposes a testable framework for investigating whether an additional large-scale divergent component exists in cosmic motion.

NO TIME BARS UNIVERSE
Zenodo
No Time Bars Universe (NTBU) is a hypothesis and methodological framework for testing whether precision physical clocks exhibit reproducible, observable residuals that cannot be fully accounted for by established relativistic, geodetic, atomic, transfer-link, and instrumental models. General relativity is treated as the quantitative null model. NTBU introduces an explicit Observability Requirement: any proposed deviation from relativistic proper-time behavior must alter a measurable dimensionless quantity or differential observable, such as a frequency ratio between different atomic-clock species, a differential gravitational-redshift response, or a correlated signal across a precision-clock network. Species-universal and environment-independent rescalings that are observationally equivalent to a reparameterization of time are excluded. The paper develops the Proper-Time Residual Test (PTRT), a preregistered falsification protocol in which conventional relativistic and metrological effects are modeled before any NTBU parameter is introduced. Candidate deviation channels include local-position-invariance tests, curvature-sensitive clock responses, variation of dimensionless fundamental constants, and scalar-field-like signals. Existing precision-clock measurements provide stringent boundary conditions on these possibilities. The framework also proposes a prospective test using the Atomic Clock Ensemble in Space (ACES): candidate parameters derived from independent data must be frozen before comparison with relevant ACES results, preventing post-hoc adjustment of the hypothesis. NTBU does not claim that general relativity has been experimentally violated, that proper time has been demonstrated to be incomplete, or that an anomalous clock residual has been detected. Its purpose is to formulate a constrained and falsifiable research program in which the strong NTBU hypothesis can be rejected by null results or subjected to further investigation only if a predeclared model successfully predicts independent observations.

Choice-Branch Timeline Transfer Hypothesis
Zenodo
The Choice-Branch Timeline Transfer Hypothesis proposes that backward time travel does not create a paradox ora newly generated timeline. Instead, a traveler selects a pre-existing branch in which the traveler's past actionalready belongs to that branch. A self-erasing branch is not selectable because a chooser cannot choose a reality inwhich the chooser never exists. If a changed past decision produces a different branch, that branch may laterconverge back into a present sufficiently similar to the original, provided the remaining causal decisions staymostly constant. The model is summarized by three principles: pre-existing branch selection, existencepreservation,and timeline convergence.

Black-Hole–White-Hole Time-Based Navigation Hypothesis
Zenodo
This preprint presents the Black-Hole–White-Hole Time-Based Navigation Hypothesis, a speculative model in which a black hole and a white hole form opposite ends of a connected spacetime navigation system. In the proposed framework, gravity attracts objects toward the black-hole end, negative gravity expels objects from the white-hole end, and multiple wormhole corridors exist between the two ends. Each wormhole corridor is connected to one fixed spatial destination, while the traveler may select the point in time at which to arrive at that destination. The traveler is assumed to be rational, informed, and equipped with advanced structural-scanning and mapping data that identify the correct black-hole system, wormhole corridor, destination, and available time points. The hypothesis also introduces an anti-gravity spacecraft that is unresponsive to both gravity and negative gravity. This technological capability allows the traveler to navigate independently, enter the system from either the black-hole side or the white-hole side, and exit from either side once the route is known. This work is an independent conceptual research proposal intended to organize and develop ideas concerning black holes, white holes, wormholes, time-based navigation, spacetime mapping, fixed destinations, selectable arrival times, and advanced spacecraft control. It is a speculative hypothesis and is not presented as experimentally verified or accepted physical theory.
