Oh and for light to be massless than logically that is the wave in a luminiferous aether concept.
I think there has to be some kind of aether. The preferred term these days is Quantum Vacuum.
So here is my idea: The aether exists. It has ground-state non-zero mass.
This is an experiment with photons in a nonlinear medium. The 3 bound photons are so called solitons. They use effective field theory to describe the behavior. This means they treat the photons as particles with an "effective mass" having an "effective attractive force". Effective is the key word here. The photons don't become massive or anything. It is just that their behavior in this medium can be approximated as massive interacting particles.
This doesn't change or affect the standard theory in any way.
Has anyone seen electrons and protons under a microscope ever?
And we still have not even ever seen an photon, even though technically that is all we ever see or are even capable of seeing
Well, mass, and every other physical quantity, is measured by its apparent effect on other things.

The real issue with calling something aether is that it is re-inventing or re-using an old term. That in itself isn't so bad if it wasn't for the massive amount of ignorant abuse that would flow from that.
Einstein himself didn't have a problem with referring to the space-time of general relativity as "new aether", which he said had different properties than the "old" or "luminiferous aether". Of course Einstein's "new aether" term never stuck which is just as well because it would now be over 100 years old and not so new any more. I think the reason it didn't stick is for the reason you said of re-using an old term which meant something different in the sense the luminiferous aether had different properties than the new aether. So what's wrong with calling it "space-time" as we do now?
If you want to call 'the aether' the electromagnetic field which exists in all space & time, then what you say appears to be correct, but it's better to call things by what other people know them to be and not a distinctly misleading name.
If you're still convinced that's somehow impossible, feel free to measure and prove to everybody there really is a medium for the EM field like luminiferous aether that Michelson-Morley didn't find, nor have numerous experiments since. It was obviously a popular idea over a century ago, but the fact it's never been found since says something to me. At what point and after how many failed experiments to detect luminiferous aether does one finally accept that it may not exist and that EM radiation seems to propagate just fine without it?

A photon (in vacuum) is a great example of something with positive energy, positive momentum, and zero mass.
I've lost track of things in the last decade and a half from the detector side, but I suspect things are still fundamentally the same today.Text

And what about the Casimir Effect? Doesn't that imply a ground-state medium does indeed exist. Maybe it doesn't have all the qualities that Michelson and Morley were looking for, but if they had been alive to witness the Casimir Effect, what would they have said?

But anyways, I was just here for a picture of a photon, as there is none, I must mozy on along on this site.
I was hoping for a picture of a photon...a picture of this positive momentum and positive energy thing. Also zero mass, should be pretty easy to take a picture of that.
