Why Does Everything Fall Down?

Gravity is the force that keeps your feet on the ground, holds the Moon in orbit, and shapes the entire universe. But what is gravity, and why does it exist at all? In this video, we explore how gravity works, from Isaac Newton's idea of an invisible force to Albert Einstein's revolutionary view that gravity is actually the curvature of spacetime. You'll learn why planets orbit stars, how gravity slows time, what gravitational waves are, and why scientists still don't fully understand gravity at the deepest level. From falling apples to black holes, gravity is one of the most familiar phenomena in everyday life—and one of the greatest unsolved mysteries in physics. ---------------------------------------------------------------------------------- CHAPTERS: 00:00​ Start 00:51 What Gravity Is? 01:54 How Gravity Works? 03:00 Gravity In Action 04:25 Unsolved Physics ---------------------------------------------------------------------------------- Music: Borealis Artist: Next Route Source: YouTube Audio Library License: Free to use with attribution ---------------------------------------------------------------------------------- #gravity #physics #einstein #science #spacetime #relativity #universe #brainscope
