1m diameter rubber sheet acts as curved space for ball bearing masses.
What it shows:
In general relativity, gravity is replaced by a curved space geometry, where the curvature is determined by the presence and distribution of matter. Objects move in straight lines, or along geodesics, but because of the curvature of space, their paths will simulate the effect of gravitational attraction. This demo gives a two dimensional view of warped space.
How it works:
In this 2-D analog, a 1 meter diameter piece of dental dam forms a...
