Why Do Things REALLY Fall? (with General Relativity)?

Things fall because gravity is like a gentle push from the Earth that makes them move toward it, just like when you roll a ball down a hill.

What's Gravity?

Imagine you're on a trampoline, and you jump. The trampoline stretches under your feet and pulls you back up. That’s kind of how gravity works, the Earth is like a big, strong trampoline that pulls things toward it.

How Does It Work with General Relativity?

Think of space as a giant sheet. When something heavy, like the Earth, sits on this sheet, it makes a dent in it. Now, if you roll a ball near that dent, it will curve and move toward the center, just like how we fall to the ground.

So when you drop your toy, it’s not magic, it's just following the dent the Earth made in space!

Examples

  1. A ball falls to the ground because gravity pulls it down, like Earth is a magnet.
  2. Imagine spacetime as a trampoline; heavy objects bend it, making things fall toward them.
  3. Gravity isn’t just a force, it’s how space and time work together.
