We live our entire lives within the Earth's gravitational field, yetrarely if ever do we experience the universality of gravitation:that every object in the universe attracts and is attracted byevery other. This page presents a "basement science" experimentwhich reveals the gravitational attraction between objects less than akilogram in mass. Knowledge in antiquity suggesting gravitation wasuniversal is discussed, and the feasibility of an experimental testusing only materials and techniques of the era is explored.Orbits in Strongly Curved Spacetime
Close-in orbits around compact massive objects such as neutron starsand black holes trace out paths drastically different from theellipses of Kepler's Laws. Since the velocity of an orbiting objectcannot attain or exceed the speed of light, Einstein's generalrelativity predicts a different energy curve, resulting in precessionabsent in Newton's theory. This page includes an interactiveapplet that lets you explore such orbits and explains the theorybehind them.by John Walker
