"Information is Geometry. Transforming complex system theories and spacetime entropy into high-performance algorithms."


Scientific Research & Innovation

I am a researcher in Theoretical Physics and Computational Science currently affiliated with the Federal University of Rio de Janeiro (UFRJ). My work applies "Code-First Physics" to solve fundamental cosmological tensions without the Dark Sector.

1. Unified Cosmology: The Reactive Entropic Gravity Framework

Focus: Cosmological Tensions ($H_0$, $\sigma_8$) & CMB Power Spectrum.

  • Core Discovery: Replaced Dark Matter with a thermodynamic response function coupled to the Hubble horizon via coefficient $\alpha \approx 0.47$.
  • The TARDIS Effect: Identified a metric compression factor $\Gamma \approx 117$ necessary to preserve thermodynamic unitarity.
  • Key Validation: Recovered the 3rd Acoustic Peak of the CMB and the cosmic expansion history indistinguishable from standard models.

2. Black Hole Universe: Geometric Inflation

Focus: Primordial Cosmology & Metric Inversion.

  • Mechanism: Non-minimal scalar coupling $\xi R\phi^{2}$ as the inflationary mechanism.
  • Critical Parameters: Identified $\xi=100$ producing exactly $N=61.7$ e-folds, solving horizon and flatness problems.
  • Geometric Constraints: Validated Gaztañaga's duality with a ratio $R_{s}/R_{H} = 1.096$, confirming our cosmos originates from a parent black hole interior.

3. Information as Geometry (Informação como Geometria)

Focus: Galactic Dynamics & Gravitational Lensing.

  • Lensing "Kill Shot": Proved that the Entropic Potential produces a deflection angle plateau, mimicking an Isothermal Dark Matter Halo ($\rho \propto r^{-2}$) without WIMPs.
  • Stability Analysis: Demonstrated that entropic forces create a "Phantom Halo" effect, maintaining Toomre stability ($Q > 1$) for galactic disks.
  • Methodology: Implemented "Code-First Physics" with 7 distinct computational unit tests including Richardson Extrapolation for numerical convergence.

4. The Reactive Universe (O Universo Reativo)

Focus: Large Scale Structure & Dynamical Friction.

  • Satellite Planes: Simulations revealed that the External Field Effect (EFE) breaks spherical symmetry, causing satellites to collapse into a co-rotating plane, solving the Milky Way satellite alignment problem.
  • Merger Dynamics: Demonstrated a "Flyby" trajectory solution for interacting galaxies, resolving the "Halo Drag" problem where standard CDM predicts rapid mergers.
  • JWST Crisis: The enhanced acceleration $a_0(z)$ drives primordial cloud collapse ~0.5 Gyr faster than $\Lambda$CDM, explaining "impossibly early" massive galaxies.

Tech Lab & Ventures

  • Asimovtech SystemsFounder & CTO. A technology lab focused on Complex Systems, Econophysics, and AI solutions.
  • PlanckDynamics Engine: A Python-based symplectic integrator for cosmological MCMC simulations.
  • EntropicGravity-Py: Open-source framework for numerical validation of Emergent Gravity.
  • Project Sentinel: Market anomaly detection utilizing Shannon Entropy.
