“The Theory of Everything: The Quest to Explain All Reality” S:1 E:16 Newton’s Gravity Unifies Earth and Sky

S:1 E:16 Newton’s Gravity Unifies Earth and Sky Gravity is by far the weakest of the fundamental forces. Learn how Newton achieved the first major unification in physics by showing that terrestrial and celestial gravity are the same. He also tacitly equated inertial mass and gravitational mass, leading to the startling theory 250 years later.
