Vhistory: Cross-Domain Real-Data Tests of a Structural Persistence Replacement Framework for Dark Matter Source Terms

Hypothesis

Any ordinary matter that becomes part of a sufficiently organised, long-lived structure and remains organised for billions of years may contribute to an accumulated gravitational effect beyond what is expected from its instantaneous visible mass alone.

This repository contains the data, methods, and results from a series of tests exploring a simple question:

Does the gravity normally attributed to dark matter increase with the persistence and organisation history of ordinary matter?

The idea being tested is called Vhistory. Rather than introducing new particles, the tests investigate whether part of the inferred dark matter contribution can be represented by a history-dependent gravitational source associated with long-lived organised structure.

The focus of this work is the data and model comparisons, not a completed physical theory.

Methodology

For each test, the standard analysis framework is kept as unchanged as possible. The dark matter contribution is replaced with a history-derived effective source while preserving the rest of the modelling approach.

The goal is to determine whether observed gravitational phenomena can be predicted from measures related to the accumulated organisation and persistence of ordinary matter structures.

Datasets and Tests

- SPARC galaxy rotation curves

- Galaxy-galaxy weak lensing

- BOSS large-scale structure power spectra

Current Results

- Better fit than the best competing CDM halo model in 118 of 143 SPARC galaxies

- Median ΔBIC approximately +11 in favour of the Vhistory replacement model

- Competitive weak-lensing results

- Competitive BOSS large-scale structure results

Observed Pattern

Across the datasets tested so far, the inferred gravitational component normally attributed to dark matter appears to increase where ordinary matter has existed within organised structures for long periods of cosmic time.

In simple terms:

ordinary baryonic matter → structure formation → long-lived organisation and persistence → increased inferred gravitational effect

The tests suggest a correlation between accumulated structural history and the additional gravity usually modelled as dark matter.

What This Is Not

- Not a claim that dark matter has been disproven.

- Not a completed physical theory.

- Not a derivation from established General Relativity.

- Not evidence that the observed pattern must be correct.

The purpose of releasing this work is to allow others to inspect the data, methodology, assumptions, parameter counting, statistical treatment, and model comparisons.

Requested Criticism

I am particularly interested in feedback on:

- Statistical fairness of the comparisons

- Hidden model flexibility or overfitting

- Parameter accounting

- Covariance treatment

- Selection effects

- Alternative explanations for the observed correlations

- Whether the observed pattern could arise from known astrophysical effects

Background

I am not a physicist. The project began as a data-driven investigation after noticing recurring patterns across multiple gravitational datasets. Large language models have been used to help translate those observations into mathematical and physical language, but the central claim being investigated remains empirical:

Does the gravity attributed to dark matter systematically increase with the age, persistence, and organisation of ordinary matter structures?

The datasets, scripts, and results are provided so others can independently evaluate that question.
