Here's why:
* Newton's Law of Universal Gravitation: This 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 gravitational attraction.
* Inversely proportional to the square of the distance between their centers: The farther apart the objects are, the weaker the gravitational attraction.
In simple terms: Gravity is the force that pulls things together, and the strength of that pull depends on how heavy the objects are and how far apart they are.
