For centuries, we believed gravity was a force pulling objects downward. Drop an apple, and gravity does the rest,simple, ...

The equivalence principle says that there is no difference between being stationary and subject to gravity tugging you and accelerating in a vehicle that's free of gravitational pull.

The equivalence principle tells you that the paths of falling junk directly inform you about the nature of gravity, and those same paths reveal a complicated geometry of the underlying space-time.

Per the equivalence principle, this should have no effect on how gravity acts upon both cylinders. So if MICROSCOPE measured any deviations, equivalence would be violated.

The Weak equivalence principle (WEP) is a key aspect of classical physics. It states that when particles are in freefall, the trajectories they follow are entirely independent of their masses.
