Here's why:
* Newton's Law of Universal Gravitation: This law states that every particle of matter 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 closer the objects are, the stronger the gravitational attraction.
* Empty Space: In the vast emptiness of space, with no other forces acting upon them, the only force that remains is gravity.
* Drifting Together: Since gravity is always attractive, the two masses will experience a force pulling them towards each other. Over time, this force will cause them to drift closer and closer together.
Important Note: While gravity is the fundamental force at play, the actual speed at which they drift together depends on several factors like their initial distance, mass, and their relative velocities.
