About 425 years ago, Galileo Galilei supposedly dropped pairs of balls of different sizes and materials from the Leaning Tower of Pisa to show that all objects accelerate at the same
rate under gravity's pull.
After all, we aren't that great at second - guessing aspects of classical reality, either: how many of us would naturally say that feathers and bricks fall at the same
rate under gravity?
A French satellite experiment has shown that objects with different masses fall at exactly the same
rate under gravity, just as relativity dictates.
And by testing the effect of gravity on BECs of two different types of atoms, an atom interferometer could test the principle that all objects, no matter their weight or composition, accelerate at the exact same
rate under gravity's pull — as Galileo Galilei supposedly demonstrated by dropping balls of different materials off the Leaning Tower of Pisa in Italy.
