222 - What is the role of gravity in the universe?
Gravity is a force that pulls everything towards each other. It's like a big hug from the universe. Imagine you have a ball, and you throw it up in the air. What happens? It comes back down, right? That's because the Earth is pulling on the ball with gravity.
Gravity also helps keep us on the ground, keeps the planets moving around the sun, and even holds the galaxies together. It's a really important force that helps our universe work the way it does.
