I built a 2D N-body simulator to explore the hypothesis that our universe exists inside a black hole. The code simulates gravitational dynamics within a membrane boundary (event horizon analog), tracks atmospheric evolution, and models dark energy as external mass injection.

After 2000 epochs: 2.7% of bodies developed breathable atmospheres.

The code is MIT-licensed and needs GPU acceleration / 3D extension. Looking for collaborators with computational resources.

Would love feedback on the physics assumptions!
