Why Gravity Is Not Really a Force _ Science for Sleep
"Gravity might feel like a force, but under Einstein's theory of relativity, it is not. It is the curvature of spacetime itself."When you place a heavy ball on a trampoline, the fabric bends. Objects roll toward the center not because of a force, but because the fabric is curved. In the same way, mass tells spacetime how to curve, and curved spacetime tells mass how to move. A ball thrown in the air is not being pulled back by a mysterious force; it is following the straightest possible path through curved spacetime. This means gravity is not a force like electromagnetism. It is the geometry…
