An anonymous reader writes "At a symposium at the Dutch Spinoza-instituut on 8 December, 2009, string theorist Erik Verlinde introduced a theory that derives Newton's classical mechanics. In his theory, gravity exists because of a difference in concentration of information in the empty space between two masses and its surroundings. He does not consider gravity as fundamental, but as an emergent phenomenon that arises from a deeper microscopic reality. A relativistic extension of his argument leads directly to Einstein's equations."
Here are two blog entries
discussing Verlinde's proposal in somewhat more accessible terms. Update: 01/12 04:48 GMT
: Dr. Verlinde has put up a blog post explaining in simpler terms the logic of the gravity from entropy paper
. He introduces it with: "Because the logic of the paper is being misrepresented in some reports, I add here some clarifications."
