D. Isaac Newton

Sir Isaac Newton figured out that every object in the Universe was attracted to every other object with a force (gravity) that is directly proportional to the product of their masses and inversely proportional to the square of the distances in between them. This was then or later know as the Universal Law of Gravitation. We also know he studied Mathematics and Philosophy which helped him come to this conclusion.
