How Did the Idea of ‘Gravity’ Change Our Understanding of the Universe?

Gravity is like a magnet that pulls things together, and it changed how we see the whole universe. Before gravity, people thought Earth was at the center of everything, but then came one super-smart guy named Isaac Newton. He realized gravity works everywhere, not just on Earth! That idea helped us understand why the Moon goes around the Earth and even why planets move in space.

Examples

A falling apple helped Newton think about gravity, now we know that apples fall because of the same force that keeps the Moon around Earth.
You feel gravity when you jump up and come back down to the ground.
The Moon stays in orbit around the Earth because of gravity, just like a ball attached to a string circles around your hand.
