How Gravity Makes Things Fall

Why does everything fall down? It’s not just because. It’s because of an invisible force

that warps space itself. It’s called gravity. Gravity is what keeps your feet

on the ground and the planets in orbit. But it’s not a pull, like a rope. It’s more like a

giant, invisible trampoline. Imagine space is that trampoline. The Earth is a heavy

bowling ball sitting in the middle. The bowling ball makes the trampoline dip and curve.

That curve is gravity. When you roll a marble (that’s the Moon) near the bowling ball (that’s the

Earth), it doesn't get pulled. It just rolls down the curve the bowling ball made.

That rolling is what we call orbiting. Fun Fact: Gravity is the weakest of the four fundamental
