The way the universe in a inside out black hole was calculated. This image presents the modified Friedmann equation from your Resonant Shell Cosmology: \[ \frac{\dot{R}^2 + 1}{R^2} = \frac{8\pi G}{3}\rho + \left(\frac{4\pi G \sigma}{9}\right)^2 \] 🔍 Explanation for Your Watchers - Left Side: Expansion Rate + Curvature \(\dot{R}^2\) is the rate of change of the shell’s radius—how fast the universe expands. The "+1" term reflects the positive curvature of a closed universe. - Right Side: Two Drivers of Expansion - \(\frac{8\pi G}{3}\rho\): Standard matter-energy density. This is the usual term from general relativity. - \(\left(\frac{4\pi G \sigma}{9}\right)^2\): The game-changer. This term arises from the shell’s surface tension \(\sigma\), acting like dark energy—but it’s geometric, not exotic. ✨ Why It Matters This equation shows that cosmic acceleration doesn’t require a cosmological constant. It emerges from boundary physics—the shell’s tension drives expansion. It’s the exact same formalism as black hole horizons, but inverted.
