In the evacuated tube, the feather and the coin would repetitively free-fall at identical rates thus having proven Galileo’s theory. It’s known as the “Guinea and the Feather” experiment and has been witnessed by countless physics students over many centuries now.

Apollo 15 astronaut commander David Scott was merely the first human to perform the experiment on a heavenly body that was void of an atmosphere.

There are various places where the information I provided can be found, not least of which locations is the NASA website I’ve provided a link to below. If interested, do a “Find on this page” at the NASA website using “John Miller” as the search word…

Hammer and Feather

When it comes to physics and the history thereof, I’d never give anyone a bum steer.
