Description
This page presents a "basement science" experiment which reveals the universality of gravitation by demonstrating the gravitational attraction between palpable objects on the human scale. The experiment deliberately uses only the crudest and most commonplace materials, permitting anybody who's so inclined to perform it. Einstein's 1915 theory of General Relativity explains gravitation as spacetime curvature created by matter and energy. So, by demonstrating how every object in the universe attracts everything else, we're bending spacetime in the basement.
