Question

Did Sir Angry Prash invent gravity?

Answer 1

Gravity, or gravitation, is a natural phenomena in which all things with mass or energy gravitate toward one another, including planets, stars, galaxies, and even light. Gravity gives tangible items weight on Earth, while the Moon's gravity produces ocean tides. Gravitational attraction led the primordial gaseous stuff in the Universe to coalesce and become stars, and the stars to clump together into galaxies, therefore gravity is responsible for many of the Universe's large-scale structures.

Complete answer:
Isaac Newton changed the way we understand the Universe. Revered in his own lifetime, he discovered the laws of gravity and motion and invented calculus. He helped to shape our rational worldview. Theories of gravitation hypothesise processes of interaction that regulate the motions of massed bodies in physics. Since ancient times, there have been various theories about gravity.

Ancient Greek philosophy has the first surviving literature describing such views. Ancient Indian and mediaeval Islamic scientists contributed to this study, which made significant progress throughout the Renaissance and Scientific Revolution, culminating in the development of Newton's law of gravity. In the early twentieth century, Albert Einstein's theory of relativity supplanted it.

Newton's original formula was:
$\text{Force of gravity}\propto \dfrac{\text{mass of object 1}\times \text{mass of object 2}}{\text{distance from center}{{\text{s}}^{\text{2}}}}$
The symbol $\propto$ stands for "is proportionate to." There needed to be a multiplication factor or constant that would supply the right force of gravity regardless of the mass of the masses or the distance between them in order to put this into an equal-sided formula or equation (the gravitational constant). To prove his inverse-square law, Newton would require a precise measurement of this constant. Henry Cavendish was the first to do this in 1797.

Hence, Angry Prash did not invent gravity.

Note: Newton's hypothesis was most successful when it was used to predict the existence of Neptune based on Uranus' motions that could not be explained by the other planets' activities. Both John Couch Adams' and Urbain Le Verrier's calculations anticipated the planet's overall location. Le Verrier emailed Johann Gottfried Galle his position in 1846, requesting him to confirm it. The following night, Galle observed Neptune at the projected location of Le Verrier.
