From Apple to Gravity

One day, I saw an apple fall from a tree. It didn’t fly sideways. It didn’t float.

It fell straight down. I asked a simple question: Why?

Why does everything fall toward the Earth? And why doesn’t the Moon fall too?

That moment led me to an idea. The same force pulling the apple also pulls the Moon.

I called this force gravity. Gravity wasn’t just on Earth. It existed everywhere

in the universe. One simple observation revealed a universal law.
