Using a Taylor series with a few terms already gives a good approximation of the real situation. In quantum mechanics, this idea is pushed much further and leads to Feynman path integrals describing the interaction of particles.
WebLecture 1 8.821/8.871 Holographic duality Fall 2014. Emergence of gravity Duality (2) implies that quantum gravity plus spacetime can emerge from a non-gravitational system. The idea itself is not new: In 1967, A. Sakharov observed that certain condensed matter systems have mathematical descriptions similar to those in GR. WebOn the face of it, m g has a very different character than m i; it is a quantity specific to the gravitational force.If you like, it is the "gravitational charge" of the body. Nevertheless, Galileo long ago showed (apocryphally by dropping weights off of the Leaning Tower of Pisa, actually by rolling balls down inclined planes) that the response of matter to …
