Inertial

Experiment which alone shows the nullify of all those adduced against the motion of the earth.

"Shut yourself up with some friend in the main cabin below decks on some large ship, and have with you there some flies, butterflies, and other small flying animals. Have a large bowl of water with some fish in it; hang up a bottle that empties drop by drop into a wide vessel beneath it. With the ship standing still, observe carefully how the little animals fly equal speed to all sides of the cabin. The fish swim indifferently in all directions; the drops fall into the vessel beneath(...) have the ship proceed with any speed you like, so long as the motion is uniform and not fluctuating this way and that. You will discover not the least change in all effects named, nor could you tell from any of them whether the ship was moving or standing still."

Galileo Galilei, Dialogo, 1632
