Gravity as Geometry

<p>if inertial mass and gravitational mass are exactly the same, everything will fall at the same speed, making it hard for a falling observer to establish that he is in a gravitational field.</p> <p>Einstein hypothesized that, not only would it be hard, but in fact impossible. This thought lead him down a rabbit hole of curved spacetime and gravity being geometry, and in the process he (arguably) solves the mysteries of action at a distance and inertial/gravitational mass, that plagued Newton. Later investigations of the theory exposes strange effects such as how the center of a black hole is not a place in space but a moment in time.</p> <p>This is the story of General Relativity.</p> <p><a href="https://www.cantorsparadise.com/gravity-as-geometry-4e02450512ff"><strong>Read More</strong></a></p>
