Isaac Newton’s investigations of gravity primarily explained that:
- Gravity acts on all objects in the universe.
He formulated the law of universal gravitation, which stated that every mass attracts every other mass with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This provided a comprehensive understanding of gravitational force and its effects on the motion of celestial bodies.
While it is true that:
- The sun is more massive than earth (which relates to the gravitational interaction between the two),
- and it is also correct that Earth is not the center of the universe (as demonstrated by the heliocentric model which gained support from gravitational principles),
the primary takeaway from Newton's work pertaining to gravity is its universal nature across all objects.
The statement about Jupiter having more moons than Earth is a separate astronomical fact and not directly related to Newton's laws of gravity.
