What would be the impact on astronomy and cosmology if the speed of light was a dependent variable and the independent variable was the energy density of dark matter?

I don't believe in Dark Matter, to me it's just a sign that we have made some seriously f'd up mistakes and we're trying to patch it up so Physicists don't lose their tenure and have to get a real job.
I haven't been able to get a somewhat simple answer on"why" there needs to be dark matter and dark energy(through google). At least nothing I could comprehend. Could anyone give a comparison or something to make this a bit easier to wrap my brain around?

There are other indications of dark matter but this is the clearest to me.

Elsewhere we talked about prior conditions from which matter emerges. When I describe dark matter I am talking about the kind of mass that has not completed the journey into the formation of particles that appear in the particle model of particle theory.
Isn't it a simple prediction to come to, that where matter exists in great quantities, i.e. galaxies for example, that pre-stage mass would have taken shape and would have remained in gravitational association with galactic structure that consists of particles that we CAN detect?

Must we google things ourselves. Where is a good link? Do you know how to embed a link in a post. For example you can use [ url=] [/url]
Like this. The Axion is a dark matter candidate.
Personally I like the idea I use in my QWC thread, Mass *has* gravity where pre-particles form from the energy background before the fundamental particles. The formation of fundamental particles leave an unused population of these pre-particles that do exert and feel gravity and so they hang around massive structure like galaxies.

Thanks for mentioning the Axion. Now if you would, please explain what you mean here:

Hi,
I say this, because there must be an existing set of particles alongside the Axion. This is a particle that can travel through solid objects.
However, the appearance of this unique particle has not revived an absolute condition for dark matter itself. Thergo, and answering your question, the dark matter candidate, may not be an actual dark matter itself.

Maybe we should start with a definition of space itself.
Some think of it as the "fabric of spacetime". To some space could be empty and is just a place where things happen. Most agree that space seems to be something other that an perfect void.
I like to think of space as infinite and filled infinitely with energy density that is characterized by continual energy density fluctuations. There are no voids.
In my view DM is a characteristic of energy density. The average universal energy density is high enough to produce energy density fluctuations that are capable of forming matter, and dark matter is that part of the energy background that has no charge and therefore doesn't stand out to be detected. It is a stage of prematter formation that exists where the energy density is above the equilibrium threshold but below the lower matter formation threshold.

I guess you are right since the volume of spacetime is implied to be zero at the instant of the big bang so everything was "potential" at that point. Correct me if you don't agree, but most BBT theorists will just say that it had volume after the first instant and will not say it was ever infinitely small and infinitely dense.
I stand uncorrected
.But getting back to the original post, photons are said to be expanding spherical waves (see bottom of page 4) as evidenced by the out of phase interference patterns in two slit experiments.
Wouldn't we have to say that the photon's spherical waves would be expanding at the speed of light? Please correct me if this is not a fair conclusion.
A single photon has a definite wavelength according to Planck's equations. If it is interfered with its size and shape changes. I can't see a pair of slits producing an expanding wavefront from light unless they are very close together, are extremely narrow, or they bounce light inside of them and produce a fan of light. Draw the lines. Light from a single pinpoint source passing through two slits without scattering should not intersect itself to produce an interference pattern.
