Here's why:

* Newton's Law of Universal Gravitation: This fundamental law states that every particle in the universe attracts every other particle with a force that is:

* Proportional to the product of their masses: The more massive the objects, the stronger the force.

* Inversely proportional to the square of the distance between their centers: The farther apart the objects, the weaker the force.

* Even tiny objects exert a pull: While the gravitational force between you and a distant galaxy is incredibly weak, it still exists. The same goes for every object you encounter, from a pen to a skyscraper.

* The Earth's gravitational pull is dominant: The Earth's massive size means its gravitational force is the strongest influence on you. That's why you feel grounded and why objects fall towards the ground.

So, even though you might not feel it, there's a tiny gravitational pull between you and every object in the universe, from the tiniest atom to the most massive galaxy. It's a subtle but fascinating force that governs the structure and evolution of the cosmos.
