Photons act pretty much like waves, not like BBs at all.
The page you referred to on the relativity denial site operates on the assumption that when mainstream experiments failed to show evidence of aether, the experiments were somehow interpreted wrong, so he's claiming that there is a luminiferous aether after all.
I don't really know, and can't speak too confidently about vacuum energy with issues like the vacuum catastrophe and the fact that we don't understand why the vacuum energy has the value we measure, but I think of light as being more self propagating, with such propagation being distorted by distortions in space-time from gravity. Maybe dragonridr or Eros can shed some light on that question that I can't.

If space is a field of ground state vacuum energy (as a minimum?) can light be the product of the quantized energy/wave packet/ propagating through disturbing/waving the field so to speak?

Agreed, but don't people treat the experiment as though it shows the entire particle being in two places at the same time?
ETA:

Just to be clear, I'm not interested in the relativity denial stuff. I know that motion is relative. I also hate that luminiferous aether term, it makes me think of that rarefied gas stuff and I don't buy that aether theory. I'm curious about the possibility of a different kind though, I guess.

please explain further...
how space is 2D ? or what do you mean by that ?

No rush, we got time.
One more question to add. How many 2D planes would equal the thickness dimension of a single layer of graphene?
Then it goes on to describe the limits which I'm not sure I understand all that well and that's one reason i wasn't confident in answering. Can you dumb those limits down a little bit or at least put the uncertainty of the model in context with respect to the difficulty in merging quantum and relativity models, and also the following issues?
...non-relativistic QM, although it cannot be the correct theory in the end, has its empirical successes. But it can never be the appropriate framework for electromagnetic phenomena because electrodynamics, which prominently encompasses a description of the behavior of light, is already relativistically invariant and therefore incompatible with QM. Scattering experiments are another context in which QM fails. Since the involved particles are often accelerated almost up to the speed of light, relativistic effects can no longer be neglected. For that reason scattering experiments can only be correctly grasped by QFT.
Unfortunately, the catchy characterization of QFT as the successful merging of QM and SRT has its limits.
Ok you misunderstand what i mean by 2 D space
A photon must be real or you wouldn't be able to read what you're reading on this message board.

I don't even think a photon is real. It only exists in math.
I partially answered that question with the diagram in this post, at the top of page 36, near the bottom of the post.
Maybe this will help me, how is a photon/wave packet/discrete bundle quantified? Is it a set inseparable "energy value"?
This is one of the coolest things in science to me, that we can tell what distant stars are made of without having to go collect a sample of them.
When the electron falls from a higher energy lever to a lower energy level it will release the energy by emitting light with this energy. Since every kind of atom has a different electronic configuration, the wavelengths of light absorbed or emitted by an element are unique to that element. It is like an atomic fingerprint. The fingerprint recorded by measuring which types of light an atom absorbs is called the Atomic Absorption Spectrum. The fingerprint recorded by looking at which wavelengths of light an atom emits is called the Atomic Emission Spectrum.
It's impossible to measure this because when you try to measure what the photon does, the "wave function collapses" and the entire photon goes through only one slit. I'd guess that on average about half the energy passes through each slit if it's still a wave, though could be 60/40 one time and 40/60 the next time (percent of energy through each slit), but I'm not sure and like I said it can't be measured, because it's always 100% through one slit and 0% through the other slit if you try to measure it.
When a photon is said to pass through both slits are you saying the entire quantity of the photon does so through each slit?

I guess I asked too much at once. I pretty much already understood most of what you said and agree that the observational data of dark energy which may be vacuum energy shows a small non-zero value many orders of magnitude smaller than predicted by QFT, and I suppose the popular view is that there might be something cancelling out the huge predicted value to yield the small non-zero value we measure, but we don't know what is cancelling it out.
So I guess the answer I was looking for was something much shorter and simpler along the lines of "yes we know about that but here are the reasons we still have confidence in the model in spite of that (list reasons); and yes QFT has been claimed to successfully unite QM and SRT though it really hasn't because of these limitations (clarify limitations) which only affect special cases like black holes (or whatever) so it we still have a high confidence in its applicability to the propagation of light in spite of those (if we do)." I'm not saying that's the answer I want just that type of content, even if the conclusions are different from those stated in the example.
Did you follow that quote I posted from the Stanford source; did that make sense to you?

Do I? You are speaking of it as though it's real. I am not surrounded by 2D space. 2D is fine for math but problems can arise when abstractions become considered real. This is just a minor example.
Is it possible to discuss this without abstractions? Like you said, wave function is not a substance. I don't even think a photon is real. It only exists in math. In reality, we don't say a water molecule is a particle and a wave (as in the wave of water). Of course a molecule is defined but I don't know and haven't found details about how a photon is defined.
Maybe this will help me, how is a photon/wave packet/discrete bundle quantified? Is it a set inseparable "energy value"?

Where are the fields, what do they look like, what do they appear as to themselves, if one could see and feel and observe everything that exists, what does the EM field appear as, and how does it work, step by step, planck length by planck length and planck time by planck time.... how long is a light Electric field until it turns into a magnetic field, and how long is it a magnetic field till it turns to electric field? Thats related to its amplitude and wavelength I suppose. Is light destroyed by local magnetic or electric fields? Not destroyed you know, but absorbed?
m or gif, of what the smartest physicists in the world think it looks like for an electron to be accelerated, and then subsequent, EM radiation to be propagated from that point, and the most detailed showing, of how that EM radiation propagates from the electron, what it appears as.
Because I know we cant see it as it propagates, we only see and detect when we finally end the propagation of EM radiation, but if they are claiming to know how it behaves, what it is, how it works... Please... find me that diagram.
It should be the simplest thing to find. Hundred years of knowing physics,I feel this isnt much to ask for. I dont care if you answer anything else in this reply or of me ever again. Thats all I want you to read of this post, the 'show me a diagram' sentence right above. Physicistspeed.

You know, there are these things called "physics textbooks" and they talk about this subject. I 've told you about a very good one for intuitive understanding---but others can be good as well. They have equations of motion and diagrams demonstrating their effects. There are also educational simulations about what you want as well.
Time to deny ignorance and work.
How about trying Google?

There was one applet which I can't find now which let you shake a charge around with a mouse and you would see the propagating fields as a consequence.

That settles it for me then, you believe the fundamental fields of reality ( for example EM field) is made of pure line. The electron is coupled to pure absolute graph, that when the electron moves the graph lines change and this is called radiation, and the local graph doesnt stay changed, so its called a wave, the graph waves.
Reality is a line graph, 3d one might ask? One might be told to read a book one might suppose. It is now known that reality is a digital calculator.
Energy is pure line. The line is made of line. The graph is made of graph. Field is field, field is graph, field is line. Electron is point. 1d, its made of energy, energy is line, energy is point. Energy is graph. Graph waves. Graph is made of pure point. Points are pure lines. Lines are made of points. Graphs are made of points and lines. A field is pure points and pure lines. Energy is a field that is a graph that is pure lines and pure points. Everything is pure everything which is a graph.

How about learning about 1-d wave equation and then classical acoustics first, it's simpler then EM having only a scalar pressure field.
OK, let's start more basic. Do you know what an ordinary differential equation is? In particular, an initial-value problem for describing equations of motion? Do you understand the concept of a 'differential equation of motion' in physics? If not, start there before complaining about how to intuitively grok quantum field theory.
