A New View Of Gravity - Science News: "Gravity, Verlinde asserts, is similar in the sense that masses move in ways that also produce more probable, higher-entropy arrangements.
Verlinde is not the first to relate gravity to thermodynamics. In 1995, Ted Jacobson of the University of Maryland demonstrated that the equations of Einstein’s general theory of relativity could be derived from basic thermodynamic principles. That result drew on work in the 1970s by Jacob Bekenstein and Stephen Hawking, who discovered parallels between ordinary thermodynamics and the physics of black holes, regions of such intense gravity that nothing that enters can ever exit. Bekenstein showed that a black hole has entropy, determined by all the matter and energy it has swallowed. Hawking demonstrated that black holes have a temperature (requiring the emission of Hawking radiation from a black hole’s surface). Since black holes are basically nothing more than pure gravity, describing them in terms of the thermo dynamic properties of entropy and temperature hinted at deeper links between gravity and thermodynamics."
