In UFT 442 we handle the deflection of light grazing the sun. With special relativity, the dynamics of such a trajectory cannot be computed, because the gamma factor diverges for v –> c. Within m theory, however, v=c is possible for m>1. An analytical calculation for light corpuscula moving at this speed gives the astonishing result that m is the “golden ratio” number of about 1.6. This is quite high. For ordinary matter (S2 star for example) we found m approx. 1. This leads us to the statement that light (or e-m radiation in general) has a different interaction with the spacetime or background field than dense matter. The mass of the photon seems to be extended in any form so that space appears “less dense” than for ordinary matter.
Since m theory allows velocities of v=c, we are able to apply the Lagrange (or identical Evans-Eckardt) equations to motion of light corpuscula. We can compute the dynamic behaviour of light in the presence of heavy masses. This is possible only by m theory. I did this for several values of a constant m. The result is that the experimental deflection angle is obtained within 2% with the value of the golden ratio. This is a very remakable result, proving the consistency of the calculations. This is a new milestone in theoretical physics.
The fact, that the m value for light equals the golden ratio, is probably the first time where this important constant of natural philosophy was derived from a principal physical theory without assuming any “philosophical principles”.
