Why Gravity Is Not a Force | Leonard Susskind

We are taught that gravity is a force. An invisible pull that keeps planets in orbit and holds us to the ground. Modern physics tells a different story. In this video, we explore why gravity is not a force in the traditional sense — and why this realization reshaped our understanding of reality. Drawing on ideas associated with Leonard Susskind and Einstein’s general relativity, this documentary examines how gravity emerges from the geometry of spacetime itself. In Newton’s picture, gravity acts across distance as a force. But Einstein replaced this idea with something deeper. Massive objects curve spacetime, and other objects simply follow the straightest possible paths within that curved geometry. When you stand on Earth, you are not being pulled downward by a force. You are prevented from following your natural geodesic in curved spacetime. Gravity is not something that acts on you. It is the structure you move within. At an even deeper level, modern theoretical approaches suggest gravity may be emergent — arising from more fundamental degrees of freedom, possibly connected to entropy, information, or holographic principles. The idea that gravity is not a force is not philosophical. It is encoded in the mathematics of general relativity. You are not being pulled. You are following geometry.
