⌛ Spacetime Curvature and Time Dilation — 2D Orbiting Clock Map

2D top-down companion of the spacetime curvature and time dilation sim: exact Schwarzschild gravitational time dilation combined with the Lorentz factor of the orbital speed, accumulated clock readings, and a GPS satellite check against the published +38.5 microseconds per day.
