UNIVERSAL FORCES

Finally at the universal level, the form is non-linear and quintic. Now there a five interacting elements in both the fields and their particles. So there must be an enormous 'black hole'of negative energy near the centre of the universe

Three of these four domains are clearly observable using optical, radio, microwave, and X-ray telescopes. What exists beyond these four is unknown to current mainstream scientific methods. Whether SFT offers any view outside our universe is not currently known.

At large scale, masses can influence each other if the gravitational forces between them is significant and this certainly occurs at the level of the solar system. In EMSFT, the celestial forces at the solar system level are long-range dipole-dipole forces. Hence there is a differential relationship between the gravitational tensor of GR and the stress tensor of EM. However, as the coordinates in both are transformed by the use of centre-of-motion coordinates, the resulting self-field equations are unlike the non-linear equations of GR or of EM.

From the mathematics it appears that there are exactly four gravitational fields all on different sized gauges; the solar system is the first and strongest, the galaxy is less strong, the super-cluster domain is next and the universal scale, one universe amongst multiverses, is the last and weakest. Each of these forms a series (as in a multipole sequence) where the centre of motion, or mass, oscillates between white and black holes. Hence there is according to GSFT an enormous black hole near the mass-centre of the universe. These 4 levels of gravitation form a series where the four forces are each based on the photon's electromagnetic structure. In other words, each can be solved via a modified version of Maxwell's equations. The first is like a differential of the everyday E and H-fields we experience on the terrestrial domain. Further, each of the four gravitational forces has a different cyclotron 'spin' associated with it in that each has its own direction of spin.

For instance the precession of Mercury is due to its cycltron spin that speeds up as Mercury approaches the Sun. This means that the total, orbital and cyclotron, rotation of Mercury becomes larger. Due to its dipolar cyclotron rotation; at the galactic domain, the spin is shifted by 90 degrees, so it nether adds or detracts from the orbital velocity; at the supercluster level it be opposite whatever it is at the solar system level and so on.

This can all be tested numerically. This is much easier to acheive than GR which needs supercomputers to crunch each problem. It does appear to calculations to give reasonable agreement with mercury's perihelion calculated from GR.
Tthe solar system force (GSFT1) is 'dielectromagnetic' (DEM) and is basically a first differential of EMSFT. The galactic force (GSFT2) is 'trielectromagnetic' (TEM) and is a second differential of EM. The super-cluster force (GSFT3) is 'quadroelectromagnetic' (QUAEM)and is a third differential of EM. Finally the universal force (GSFT4) is 'quintaelectromagnetic' (QUIEM) and is a fourth differential of EM. This means that these tensors (GSFT1,GSFT2,GSFT3,GSFT4) tend to be huge but manageable due to the centre-of-motion coordinate transforms that reduce the complexity of the problem.
