The simple answer is because a photon has no charge.

But if the entirety of the universe is one big/infinitely many mini electric field and magnetic field...combined... when a photon goes off, why doesnt it interact with the neighboring electric and magnetic fields which are everywhere!
I think I looked into this before, and determined that when people say there's no interaction, what they really mean is that any such photon interaction is usually small enough to be negligible, so for most practical purposes there's no interaction.
Delbrück scattering, the deflection of high-energy photons in the Coulomb field of nuclei as a consequence of vacuum polarization has been observed. However, the process of scattering of light by light, has not been observed.[1] In both cases, it is a process described by Quantum Electrodynamics (QED).

That the eigenvector of mass is not quite the same as the eigenvector of flavor?

Ok but what im asking about is; A photon,em radiation is thought to be an electric field interacting with a magnetic field alternatingly constantly. If the entire universe is full of an EM field ( Im also curious how a single 3d (field can and does exist in the first place) field can consist of 2 separate components, how are the electric and magnetic components connected as the same field and how does this field exist everywhere.
So what im wondering is if Em radiation is created which is part of this fields parts, electric field and magnetic field interacting with each other, why the entirety of electric and magnetic field components of the all encompassing field isnt interacted with by a moment of light in an area. If a photon is made, isnt it made by an electron vibrating the em field, and that vibrated em field is the photon, well if you can just take an electron anywhere and do that, it is assumed the electric and magnetic fields exist everywhere just waiting to be disturbed, so when an area is disturbed, why does that disturbance create a cascading effect
why doesnt the disturbed magnetic field create an electric field, which disturbs immediate magnetic fields, which disturb near by electric fields?

A New Preonic Model for the Composition of All Known Matter and Energy
by John SkieSwanne

I am one of those who firmly believe there exists something smaller than quarks, leptons and even gauge bosons. That preons do exist.

I'm perplexed why some 'particles' have identical preon arrangements.
Indeed. Here you see two particles having the same arrangements - the neutrino and the gauge boson. I too am perplexed about this feature, but not surprised. Both have very low mass and are neutrally charged. That's why I think these two properties are related to the arrangement (the "sequence") of the preons. The same should go for the spin too. I don't know, maybe "aababb" gives particles with spin=2, and "aaabbb" gives particles with spin=1/2. Like DNA sequence, the end result depends on the sequence.
We show that a class of background independent models of quantum spacetime have local excitations that can be mapped to the first generation fermions of the standard model of particle physics. These states propagate coherently as they can be shown to be noiseless subsystems of the microscopic quantum dynamics. These are identified in terms of certain patterns of braiding of graphs, thus giving a quantum gravitational foundation for the topological preon model proposed by one of us.
These results apply to a large class of theories in which the Hilbert space has a basis of states given by ribbon graphs embedded in a three-dimensional manifold up to diffeomorphisms, and the dynamics is given by local moves on the graphs, such as arise in the representation theory of quantum groups. For such models, matter appears to be already included in the microscopic kinematics and dynamics.

You happened to post this while I was meditating upon an explanation for mass pattern in the standard model. Coincidence? I think not...
This is really interesting!
I notice this twist of spacetime can even account for chirality (the electron neutrino can come in two different patterns).

The theory deepens string theory and fleshes out the concept. It also goes nearly all the way to unifying quantum mechanics with the observable universe at macro scales.

Yes, I noticed the same thing. It's really intriguing!
One thought, though. In this picture...
, one can see that electrons have more twists than quarks. Yet electrons are less massive than quarks. Neutrinos are OK (they have no twist relative to the others), but electrons leave me wondering how come more twist means less mass for this specific case.

So is the EM field infinite photons (or not infinite as in uncountable, but infinite as in moment to moment their number changes) that are touching or near touching, and when an electron is accelerated, its not that it shoots the nearest photons surrounding it from point A to point B, but that the photons react as a newtons cradle in a way, the balls being the photons?
But then again it is more like how water waves, if the molecules of water in a still pool represented the photons of the EM field at equilibrium, and then a finger or electron was dipped into this field, the molecules would not move as the wave, the wave is an energetic and momentary displacement of the position of the quanta.
And so theoretically as perhaps one could measure the transfer of energy from one molecule to another, the transfer of energy from one photon to another is the particle nature?
Its near impossible to get this network of photons to like a newtons cradle send energy in a straight line, so that is why it is said they are particle in nature, yet also always wavelike when detectable as an energetic phenomenon.
