A simple way to measure the shape of warped spacetime
Background
I've wondered for years about ways to visualize how mass (and hence gravity) affects the curvature of spacetime. … The question is not about astrodynamics and orbits but the curvature of spacetime.
Assumption: The distance between the mass and the mirror is identical between the two scenarios. …
