Correct Answer:
A. Newton
Explanation:
The correct answer is Newton because Sir Isaac Newton formally published the mathematical laws governing gravity in his groundbreaking 1687 work, Philosophiae Naturalis Principia Mathematica.
- Step 1 (The Scientific Principle): Newton's Law of Universal Gravitation states that every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
- Incorrect Options:
- Dalton is incorrect because John Dalton is famous for pioneering modern atomic theory and researching color blindness, not gravitation.
- Einstein is incorrect because Albert Einstein developed the Theory of General Relativity, which describes gravity as the curvature of spacetime rather than postulating the initial universal law.
- None of these is incorrect because Newton is the exact historical scientist responsible for this law.
