    en.wikipedia.org/wiki/Gravitation_(book)

    Gravitation is a widely adopted textbook on Albert Einstein's general theory of relativity, written by Charles W. Misner, Kip S. Thorne, and John Archibald Wheeler. It was originally published by W. H. Freeman and Company in 1973 and reprinted by Princeton University Press in 2017.

    en.wikipedia.org/wiki/Gravity

    In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction primarily observed as mutual attraction between all things that have mass.Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force and 10 29 times weaker than the weak interaction.

    Objects are falling to the floor because the room is aboard a rocket in space, which is accelerating at 9.81 m/s 2, the standard gravity on Earth, and is far from any source of gravity. The objects are being pulled towards the floor by the same "inertial force" that presses the driver of an accelerating car into the back of their seat.

    [55] [b] They attributed the motion of objects to an impetus (akin to momentum), which varies according to velocity and mass; [55] Buridan was influenced in this by Ibn Sina's Book of Healing. [1] Buridan and the philosopher Albert of Saxony ( c. 1320 – c. 1390 ) adopted Abu'l-Barakat's theory that the acceleration of a falling body is a ...

  6. Graviton - Wikipedia

    en.wikipedia.org/wiki/Graviton

    The graviton must be a spin-2 boson because the source of gravitation is the stress–energy tensor, a second-order tensor (compared with electromagnetism's spin-1 photon, the source of which is the four-current, a first-order tensor). Additionally, it can be shown that any massless spin-2 field would give rise to a force indistinguishable from ...

    Theoretical physicist Rainer Sachs from the University of California, Berkeley, observed that The Large-Scale Structure of Space–Time was published within just a few years as Gravitation and Cosmology by Steven Weinberg and Gravitation by Charles Misner, Kip Thorne, and John Archibald Wheeler. He believed these three books can supplement each ...
