In physics, Hooke inferred that gravity obeys an inverse square law and arguably was the first to hypothesise such a relation in planetary motion, [19] [20] a principle Isaac Newton furthered and formalised in Newton's law of universal gravitation. [21]
In 1671, Robert Hooke speculated that gravitation is the result of bodies emitting waves in the aether. [88] [i] Nicolas Fatio de Duillier (1690) and Georges-Louis Le Sage (1748) proposed a corpuscular model using some sort of screening or shadowing mechanism.
Robert Hooke published his ideas about the "System of the World" in the 1660s, when he read to the Royal Society on March 21, 1666, a paper "concerning the inflection of a direct motion into a curve by a supervening attractive principle", and he published them again in somewhat developed form in 1674, as an addition to "An Attempt to Prove the Motion of the Earth from Observations".

Hooke's lecture "On gravity" was at the Royal Society, in London, on 21 March. [2] Borelli's "Theory of the Planets" was published later in 1666. [ 3 ] Hooke's 1670 Gresham lecture explained that gravitation applied to "all celestiall bodys" and added the principles that the gravitating power decreases with distance and that in the absence of ...
Robert Hooke speculated in 1671 that gravitation is the result of all bodies emitting waves in all directions through the aether. Other bodies, which interact with these waves, move in the direction of the source of the waves. Hooke saw an analogy to the fact that small objects on a disturbed surface of water move to the center of the ...
Gravity is one of the universe's fundamental forces. Einstein's theory linked space, time and gravity. It holds that concentrations of mass and energy curve the structure of space-time ...
Hooke's statements up to 1674 made no mention, however, that an inverse square law applies or might apply to these attractions. Hooke's gravitation was also not yet universal, though it approached universality more closely than previous hypotheses. [81] Hooke also did not provide accompanying evidence or mathematical demonstration.
Groundbreaking discoveries in science often come with two iconic images, one representing the breakthrough and the other, the discoverer. For example, the page from Darwin’s notebook sketching ...
