We take Newton's laws of gravity for granted. Surely the inverse square law is the most accurately tested law in physics, right? WRONG. Ironically, gravity has been tested more accurately in the cosmos, than in the laboratory. Today we discuss a fascinating lab experiment putting the inverse square law to the test!
