Galileo allegedly dropped unequal weights from Leaning Tower between 1589-1592. Viviani claimed experiments were conducted with professors and students. Most historians consider it a thought experiment rather than physical test. Galileo's earlier prediction was that same-material objects fall at same speed. Experiment disproved Aristotle's theory of gravity
