Here's why:
* Newton's Law of Universal Gravitation: This law states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
* Inverse Square Law: The "inverse square" part is key. This means that if you double the distance, the force of gravity is reduced by a factor of 2 squared, which is 4.
In summary: Doubling the distance weakens the gravitational force significantly, not just by half.
