Have you ever looked at Earth and ask yourself why people, say, in the Southern Hemisphere, don’t just fall off the planet?
Here on planet Earth, the reason we do not fall off is because gravity is constantly pulling everything towards the center of the Earth. Even though you cannot feel yourself being pulled, gravity is always happening. In fact, you would definitely know if it ever stopped because suddenly, you’d find yourself floating in the air. And you wouldn’t be alone: gravity does not just keep you tied to the Earth, but everything around you too.
