Final answer:
The principle that large and small masses fall at the same rate exemplifies that the same physical rules apply throughout the universe. This demonstrates universality, as embodied in Newton's law of gravitation, the Standard Model, and the Big Bang theory.
Step-by-step explanation:
The observation that large and small masses fall at the same rate, which has been tested on Earth, in space, and on the moon, demonstrates that the same physical rules apply throughout the universe. This is one of the remarkable discoveries about nature—the universality of physical laws—and it suggests that the same laws governing the motion of objects on Earth also determine the motion of celestial bodies in space. This principle is embodied in Newton's law of gravitation and is also a fundamental aspect of the Standard Model in particle physics and the Big Bang theory.
