Pendulums swing at intervals independent of their mass
HERE’S THE INTERESTING PART
A heavy bowling ball and a tiny hollow marble suspended on equal lengths of string will perfectly match each other swinging back and forth. The sheer weight of the bob literally does not matter. The fundamental mathematics of the swinging arc rely exclusively on the localized pull of gravity and the exact length of the tether, rendering the actual physical mass entirely irrelevant.
One discovery leads to another.
