One of the first experiments carried out on the Moon.

Which hits the ground first, a hammer or a feather?

It can be surprising even for normal people.

Another experiment confirming the theory of gravity, which will remain a theory… but the result of this experiment is a fact. This experiment can be repeated under other conditions to develop the theory in many ways, and that’s what has been done for centuries.

In fact, in high school in France, the same experiment is done with balls of the same shape and size but with different masses, taking photos at regular intervals and to create a graph of position versus time. I don’t know how many students do it each year, but several tens of thousands seems like a minimum.

For those interested, in the old days, a well-known scientist used to drop objects from the top of the Tower of Pisa to test his theory.
