Why gravity doesn't need a fuel supply to shape the universe
In short: If gravity has been shaping the cosmos for billions of years, why hasn't it run out of energy? This video explores the fundamental misconception that gravity functions like a cosmic engine consuming fuel.
The video traces the mechanics of gravity from the simple fall of an apple to the complex curvature of spacetime described by Einstein. It examines how planetary orbits persist for billions of years without continuous propulsion and clarifies why massive gravitational events do not deplete the force.
Ultimately, the presentation argues that gravity is not a process of burning through a hidden energy supply, but is instead an inherent part of the universe's structure.
