This repository hosts the interactive Single-Page Application (SPA) and theoretical manuscript for the research paper: "Are We Really In A Black Hole? Theoretical Foundations, Observational Constraints, and the Schwarzschild-de Sitter Duality."
The project explores Black Hole Cosmology (BHC)—the hypothesis that our observable universe is the interior of a non-singular black hole that formed in a higher-dimensional "parent" universe. By synthesizing the Einstein-Cartan theory with modern Unimodular Gravity, this paper provides a framework that resolves the Big Bang singularity problem and offers a physical origin for Dark Energy.
The included index.html file acts as an interactive cosmological journal, transforming abstract physics into explorable data:
- The Schwarzschild Coincidence Plot: An interactive scatter plot comparing the mass-to-radius ratios of stellar black holes, supermassive black holes, and the observable universe.
- Holographic Boundary Simulator: A visual demonstration of the Covariant Entropy Bound, showing how 3D volume properties emerge from 2D boundary data.

Torsion-Mediated Bounce: How Einstein-Cartan spacetime torsion prevents infinite density at the center of a black hole, triggering an internal "Big Bounce."
Mass Identity (Rs = RH): The mathematical alignment demonstrating that the Schwarzschild radius of the universe's mass is equal to the current Hubble radius.
Cosmological Coupling: Recent observational evidence suggesting that supermassive black hole growth is coupled to the universe's expansion via a Universal Growth Index (gamma ~ 0.618).
The mathematical and observational evidence presented in this paper suggests that the observable universe is a self-contained, holographic projection within a Schwarzschild-de Sitter manifold.
While standard cosmology relies on the ad-hoc additions of Cosmic Inflation and a mysterious Dark Energy field to explain our universe's structure, Black Hole Cosmology provides a more elegant geometric solution. By replacing the mathematically impossible singularity at the dawn of time with a torsion-mediated "Big Bounce," we establish a natural, physical boundary—the event horizon—that dictates the expansion and entropy of our cosmos.
Ultimately, the proposition that we reside inside a black hole bridges the gap between general relativity and quantum mechanics. Future data from gravitational wave observatories (like LISA) and precise measurements of Cosmic Microwave Background parity anomalies will be the final acid tests needed to confirm if our cosmic horizon is, indeed, the inside of a black hole.
