Bending Spacetime in Your Basement: A Simple Gravity Experiment
2025-03-11
This article describes a simple physics experiment that can be performed at home using readily available materials. It demonstrates the existence of universal gravitation using a torsion balance. The experiment cleverly uses differential measurement to cancel out Earth's gravity, allowing observation of the gravitational attraction between small objects, thereby validating the concept of spacetime curvature in Einstein's General Relativity. The author even speculates on how history might have unfolded if Archimedes had performed this experiment in antiquity.
