Why Doesn’t Gravity Ever Run Out?

Gravity has been shaping the universe for billions of years. So why hasn’t it ever run out of energy? The question sounds simple, but it exposes a surprisingly common misunderstanding about how forces, energy and motion actually work. In this video, we follow gravity from a falling apple to planetary orbits, collapsing stars and Einstein’s curved spacetime. We’ll see why gravity does not need a constant supply of fuel, where the energy of a falling object really comes from, why planets can orbit for billions of years without being continuously pushed, and why enormous gravitational events do not mean gravity itself is being “used up.” The answer changes the way gravity should be pictured entirely. Gravity is not a cosmic engine burning through a hidden fuel supply. It is part of the structure of the universe itself. -- DISCUSSIONS & SOCIAL MEDIA Commercial Purposes: insanecuriositybusiness@gmail.com Tik Tok: https://www.tiktok.com/@insanecuriosity Reddit: https://www.reddit.com
