Open, peer-reviewed cosmology research reveals a reproducible solution to the Hubble and S8 tensions using transparent numerical methods and public code.

Independent validation is the core of scientific integrity. By releasing every line of code and dataset, we invite scrutiny to confirm or challenge these results.”
— Joel Almeida, Scientific Director at ExtractoDAO Labs

CURITIBA, PARANá (PR), BRAZIL, November 28, 2025 /EINPresswire.com/ -- The team at ExtractoDAO Labs, led by cosmologist Joel Almeida, has submitted for peer review the results of the Dead Universe Theory (DUT) — a new gravitational framework that simultaneously resolves the two most significant observational discrepancies in modern cosmology.

All numerical results presented in this announcement are fully reproducible through publicly available scientific code. Independent researchers can verify the findings using the exact same algorithms, parameters, and datasets released by ExtractoDAO Labs on GitHub and Zenodo. This ensures transparent, independent validation of the proposed resolutions to the Hubble tension and the S8 growth-rate anomaly — fully aligned with modern standards of open scientific reproducibility.

? The Hubble Tension — disagreement between local expansion rate and CMB-inferred values
? The Growth/S8 Tension — observed structure formation slower than ?CDM predictions

Using fully open, independent, and reproducible scientific codes, DUT achieves:

H0(local) = 73.52 km/s/Mpc

H0(CMB) = 67.39 km/s/Mpc

fs8(z = 0) = 0.4224

Structural suppression ˜ 10% at z < 1

??² ˜ –211.4 relative to ?CDM (same datasets)

These results — the focus of more than $14 billion USD in global scientific efforts over the past decade — arise naturally from one self-consistent physical parameter set.

Dual independent numerical engines — scientifically verifiable

DUT simulations combine accessible computation with HPC-grade reproducibility:

A) COSMOMC-DUT (Python RK4) — real-time scientific visualization
B) CLASSICMC-DUT (Fortran/C++) — deterministic high-performance execution

All results can be directly reproduced by any research group:

?? Public and permanent repositories:

3: Zenodo — validated code and outputs
https://zenodo.org/records/17752029

Open Science — International Verification

All theoretical equations, numerical solvers, and dataset calibrations are fully transparent.
Every numerical claim in the manuscript can be reproduced exactly using the public code.

This work marks the beginning of a global effort to independently test
whether DUT can supersede ?CDM across the full cosmic dataset.
