In the folklore of physics, no story is better known than the tale of Galileo dropping balls from the Leaning Tower of Pisa and proving that gravity accelerates all objects equally regardless of their masses or composition. This is called the "equivalence principle," and it is a cornerstone of modern physics. But was Galileo correct?
