Flavors one, two and three seem like a progression from four to six dimensional matrices (4, 5 and 6). Six would be a singularity.

Can symmetry breaking under the gauge transformation be understood, well not exactly but kind of as: There were two linearly independent bases for the spinor field before the symmetry breaking and under the transformation the two independent spinor state collapses to give a spinor field with two linearly dependant or just one linearly independent component-direction. And because of the singularity associated with the transformation, the symmetry breaking is irreversible unless, the single component spinor breaks down to a combination of two independent states. And so, avoiding singularity for some special reason-to describe the steady state at equilibrium during transition as described by the Higgs mechanism, the spontaneous symmetry breaking produces two different interactions from what used to be a single combined form. Does that make any sense? The symmetry breaking happened on a sphere( infinite solution-from non zero minimum field). Contrast to that if it had happened on a point(single solution-from a zero minimum) the lower Omega would be bounded at zero. Does the former imply that even if we keep on finding more fundamental particle in the course of scientific advancement, we will never hit the Omega = zero ; setting the bound that real particles could not be made up of virtual particles and the two are distinct. This idea is particularly really exciting to me because I recently wrote an ameteur discussion that "all real particles are emergent from the localization of gravitational waves(also quantization). Is it possible that the smooth transition can happen two ways, like you could connect two points with an concave or convex paths. But since this is a single point of defect, the two states by quantum transformation are superposed into like a superposition of the two states, in the same point-giving the dipole? Also, Is two structures with different orientation special or could structures with more orientations could come together. What would happen when a third orientation hits the boundary of the two? Could it be that the orientation would weigh in towards either one because of the amplitude of the real components of the third guy aligns more towards either of the two, and so the transition influences the whole structure to acquire the same orientation? The Higgs field being zero at the boundary allows only one of the two poles to be real, and hence creating the magnetic monopole in the theory. This would mean that magnetic monopoles could exist together with this other imaginary state. In condensed matter systems, the quasi particles when described as point like defects, can propagate. Could the defect in the Higgs field propagate, as the energy densities on either sides of the boundary (which is now almost just the point) evolve differently? Could there be an oscillatory behavior? If you could have different pairs of defects form groups and smoothen out, and the fact that the defect particles could propagate as in condensed matter system, and oscillate as described by the differently evolving, energy densities on different sides; could this possibly allow the same particle in such a field to have mass that changes as the system evolves, and could it have anything to do with Majorana mass?

The answer is obvious. We are in Euclidean space inside an elliptic plane. It's just light is red-shifted by elliptic gravity.

@@jacobvandijk6525 to quickly respond I would say there is a progression of forces starting with the photon of three real dimensions, graviton of three dimensions but one imaginary, magneton of three dimensions two imaginary and vanderton of no real dimensions. The magneton for positive charge, strong nuclear force and when pressed down to a lower scale the weak nuclear force.

After listening to Alan's lectures for hours this kind of lecture style is, sorry, but just horrible. Why this rushing? Don't try to fill the blackboard with text, just write the minimum and try to explain what is hard to understand and what you are thinking about all that. Make space for interesting questions and ideas...
