Question: Who originated the proposition of the theory of gravitation?

Gauge theory gravity (GTG) is a theory of gravitation cast in the mathematical language of geometric algebra.  To those familiar with general relativity, it is highly reminiscent of the tetrad formalism although there are significant conceptual differences.  Most notably, the background in GTG is flat, Minkowski spacetime.  The equivalence principle is not assumed, but instead follows from the fact that the gauge covariant derivative is minimally coupled.  As in general relativity, equations structurally identical to the Einstein field equations are derivable from a variational principle.  A spin tensor can also be supported in a manner similar to Einstein–Cartan–Sciama–Kibble theory.  GTG was first proposed by Lasenby, Doran, and Gull in 1998 as a fulfillment of partial results presented in 1993.  The theory has not been widely adopted by the rest of the physics community, who have mostly opted for differential geometry approaches like that of the related gauge gravitation theory. <SEP>  The theory proposed a mechanical explanation for Newton's gravitational force in terms of streams of tiny unseen particles (which Le Sage called ultra-mundane corpuscles) impacting all material objects from all directions.  According to this model, any two material bodies partially shield each other from the impinging corpuscles, resulting in a net imbalance in the pressure exerted by the impact of corpuscles on the bodies, tending to drive the bodies together.  This mechanical explanation for gravity never gained widespread acceptance, although it continued to be studied occasionally by physicists until the beginning of the 20th century, by which time it was generally considered to be conclusively discredited. Le Sage's theory of gravitation is a kinetic theory of gravity originally proposed by Nicolas Fatio de Duillier in 1690 and later by Georges-Louis Le Sage in 1748. <SEP> Nicolas Fatio de Duillier {'1': ", '2': ", '3': ", '4': "} (also spelled Faccio or Facio; 16 February 1664 – 12 May 1753) was a Swiss-born mathematician, natural philosopher, and inventor.  Fatio is known for his work on the zodiacal light problem in astronomy, for originating the "push" or "shadow" theory of gravitation, for his close association with both Christiaan Huygens and Isaac Newton, and for his role in the Newton v. Leibniz calculus controversy.  He spent much of his adult life in England and Holland.  He also invented and developed the first method for fabricating jewel bearings for mechanical watches and clocks. <SEP> Wholistic reference is reference to the whole—with respect to the context.  In its strongest, unqualified form, the principle of wholistic reference is the proposition that each and every proposition, regardless how limited the referents of its non-logical or content terms, refers to the whole of its universe of discourse.  According to this principle every proposition of number theory, even an equational proposition such as 5 + 7 = 12, refers not only to the individual numbers that it happens to mention but to the whole universe of numbers.  The relation verb ‘refers’ is being used in its broad sense (loosely “is about”) and not as a synonym for ‘names’ in the sense of “is a name of”.
