It will take a while. :) But in the meantime I'll replace the rowboat analogy with a more apt one. One description of gravitational attraction is that of a mutual attraction between two bodies with mass. It is similar in that regard to magnetism or Coulomb attraction. Place a magnet on a table and a piece of ferromagnetic metal near to it, and they will both slide towards one another if their masses are on the same order. (If the masses are not on the same order, this will still happen but just not be readily perceived.) The situation of a photon being attracted to a massive object without the massive object being attracted (pulled) in the direction of the photon is like that of a magnet that pulls on a ferromagnetic object without the object pulling the magnet towards it as well. The magnet would stay in place on the table, undisturbed, while only the ferromagnetic object slides towards the magnet. Eric
