Galileo used thought experiments to test many assumptions, including the notion that heavy objects fall more quickly than lighter objects when they are dropped. Lacking access to either a vacuum chamber or a planetary body that has no atmosphere, he nevertheless correctly predicted that all falling objects would accelerate at the same rate in the absence of air resistance.
