This year's gravity essay contest results are in: http://www.gravityresearchfoundation.org/announcements.html [Broken] The five winning papers are published in the International Journal of Modern Physics D: http://www.worldscinet.com/cgi-bin/details.cgi?id=jsname:ijmpd&type=all along with selected papers (after peer review) among those with honorable mentions. Of last year's 27 honorable mention's, 21 were published in the December 2008 edition. Two years ago I used Physics Forums to compute the relativistic force of gravity in Newtonian form for Schwarzschild and Gullstrand-Painleve coordinates. Eventually ZapperZ locked the thread, but not before I completed the calculations for Schwarzschild and most of Gullstrand-Painleve: https://www.physicsforums.com/showthread.php?t=126996 This gives an exact solution to a problem that is usually approximated with the "Post Newtonian Expansion" technique. I became aware of the gravity essay contest only a few days before it closed and quickly typed up a paper that included the results of these calculations: http://www.brannenworks.com/gravity2009.pdf The paper includes a calculation showing that gravity might be thought of as resulting from a flux of particles emitted by massive objects. As is well known, Newton's gravitation law follows from assuming that the force is proportional to the flux density, and that the velocity of the flux is infinite. In the paper, I showed that for the static case, to first order Einstein's gravity for a black hole is obtained by making the assumption that the force is proportional to a flux with the additional provision that the flux interacts with itself so as to increase its flux density proportional to the square of the flux density. This is what one would obtain for a Feynman diagram where two flux particles interacted to produce one (or two I suppose) more. The paper picked up an honorable mention. Apparently, I'm the only amateur to get one of these recently; I looked back as far as 2004. Abstracts for winning and honorable mention papers are listed here: http://www.gravityresearchfoundation.org/abstracts.html [Broken] I haven't been very active around here for a while, at least partly because having the thread I was using to calculate with locked for no valid reason left me with a bad taste in my mouth. But since the heart of this paper was created on physics forums, and since physics forums is oriented towards amateurs interested in physics, and since the subject of the paper is a "beyond the standard model" sort of thing, I thought it was appropriate for me to announce it here. It's not every day that the pros pay attention to the amateurs.
