This simulation visualizes Einstein's General Relativity using the Schwarzschild metric for non-rotating masses.

Spacetime curvature: The grid represents 2D space where height = gravitational potential (Φ = -GM/r).

ds² = -(1-2GM/rc²)dt² + (1-2GM/rc²)⁻¹dr² + r²dΩ²

Light bending: Photons follow null geodesics, bending by angle α = 4GM/(rc²).

Orbital precession: Perihelion shift Δω = 6πGM/(c²a(1-e²)) per orbit (Mercury: 43"/century).

Event horizon: At r = 2GM/c² (Schwarzschild radius) - the "point of no return".
