🚀 Neste projeto encontro analiticamente constantes cosmológicas do Universo a partir de um banco de dados do redshift de Super Novas do tipo Ia. Para isso foi usado o Monte Carlo da Cadeia de Markov com o fim de determinar a covariância entre diferentes grandezas e de encontrar a máxima verossimilhança de suas respectivas elipses de incertezas.

Equations of Motion from a Lagrangian of a cosmological model with fading dark matter and interacting quintessence, implemented into CLASS

MDP-Ls (Matter Density Perturbations for Ls) is a software tool designed to compute both linear and non-linear matter density perturbations within the LsCDM cosmological model.

Constructed for the study of viable dark energy f(R) models and the extraction of the expected enhancement or suppression of gravitational waves.

GIFT Framework | Deriving physics from topology E₈×E₈ × K₇ → Standard Model + Cosmology 33 predictions • 0.21% deviation • 0 parameters • Lean 4 + Coq verified

Python implementation of Topological Entropic Gravity (Hughes 2025) for solving S8 tension.

A novel theoretical physics framework that derives spacetime from quantum information.

Based on a Fortran code developed by Pier-Stefano Corasaniti (LUTH), the goal of this Python/C code is to provide an efficient yet easy to use library to compute the mass of the most massive galaxy cluster in a given redshift bin.

This program classifies the universe as flat, open, or closed based on the matter density parameter (Ωₘ) and dark energy density parameter (ΩΛ). The user enters the Hubble constant, Ωₘ, and ΩΛ, and the program uses these to determine the universe’s geometry.

Research in fundamental theoretical physics. Nothing is assumed. Everything is derived.

Modeling dark energy propagation through multilayer resonance fields. A continuation of the SvetLuna Research Continuum (2025).

Fully reproducible cosmology pipeline testing a Siamese Interference Dark Sector via three independent falsification probes (Hubble expansion, effective equation-of-state, interference entropy). Current model over-accelerates the Universe; future Study II will test inverted interference toward cosmic deceleration.

Exploring the universe as a self-organizing information system: compression, entropy & consciousness.
