Strange that we need to go to these lengths just to determine which way the ground is, when any object with mass seems to find it with no problem...
LOL, true 'nuff...although once you start pulling any Gs, where the object believes the "ground" is can change wildly. In an airplane during a well-executed barrel roll, an "object with mass" will believe the "ground" is the bottom of the airplane for the entire maneuver, even when the airplane is upside down.
