Magnetic mass is a property of quark-gluon 'plasma'. This 'plasma' is the highest energy state of "matter" known to man, theorized to exist instants after the big bang, and can be created in lab environments by smashing two very heavy (generally gold) ions together. I put quotes around plasma and matter because in general, plasma is referring to stripped ions and electrons, but in this case it is referring to atoms that have been shattered into their constituent soup.
And I put quotes around matter because even after smashing gold atoms apart, we can account for every bit of energy except for the "massive" particle that gives all matter its mass.

As far as photons having mass, correct they have zero rest mass, but that makes the equation: E = pc or momentum times speed of light. Since light photons have energy, and energy can be written as:

1/2mv^2 (for light v = c the speed of light), you get an effective mass E = 1/2 m(effective) * C^2.

It doesn't really come into play anywhere, except for when you use its momentum to push things like in a solar sail.

the subject including your "theories" is they are relatively only speculations. you utilize meaningless words and words like "commute swifter than time", "explode or evaporate", "a photon that has amassed greater mass than popular", "a different state of flux or happenstance", and "elementary debris who then camoflage themselves as different debris". except you have concrete motives for those words and speculations, no person can understand what you attempt to assert. besides, a valid theory must be testable. Your "theories" are too obscure and too ambiguous to be testable.
