Gravitational attraction between photons

A photon has a disc-shaped 3D matter-core. 3D matter-cores of photons are under constant gravitational actions. Perimeter surface of a photon’s 3D matter-core has very high convex curvature due to its minute radial size. This is instrumental for very high gravitational action on it by universal medium to maintain radial size of the 3D matter-disc constant and to maintain 3D status of quanta of matter in the disc. However, the faces of 3D matter-core have minute convex curvatures that are sufficient to produce propelling efforts on it by universal medium. Gravitation and apparent attraction between 3D matter-bodies due to gravitation takes place independently in each plane. Gravitation can act only on curved surfaces of 3D matter-particles. As gravitational actions on disc-faces of 3D matter-cores of photons are very minute and used to provide movements of 3D matter-core, they may be ignored as they do not contribute towards gravitational attraction. Major parts of gravitational actions are confined to peripheral surface of 3D matter-disc in a photon. Hence, gravitational attraction can take place only between 3D matter-cores of photons, whose disc-planes coincide. Extent of universal medium between 3D matter-cores of two photons is always less than the extents of universal medium on their outer sides. Hence, higher gravitational efforts on the outsides of 3D matter-cores overcome lower gravitational efforts from inner sides and tend to move the 3D matter-cores towards each other. This action is gravitational attraction between two photons. Since discs of 3D matter-cores of photons are practically very thin and spin about one of their diameters, time interval for its disc-plane to exist in any one plane is extremely short and depends on their 3D matter-contents (frequency). Gravitational attraction between two photons takes place only when disc planes of their 3D matter-cores coincide in a plane and lasts only as long as this coincidence exist. Therefore, once gravitational attraction is active between any two particular photons, it may take very long time (or never) to repeat similar gravitational attraction between them. However, when photons are constituents of superior 3D matter-particles, their paths are controlled so that disc-planes of their 3D matter-cores become coplanar within reasonable intervals so as to provide a mean (average) value for gravitational attraction between the superior 3D matter-bodies. Hence, magnitude of gravitational attraction between two 3D matter-bodies is comparatively too small comparable to apparent attraction between constituent photons in both bodies, whose disc-planes are assumed coplanar.
