Phys, does the rotation curve of galaxies guarantee the existence of dark matter? I would think that a logical mind must realize there is the possibility of another explanation even that one of our fundamental tenets may be wrong.
One more question phys and I will explain after your answer. Suppose that the result of the BB was the creation of a single proton and no other particles, how much space would be created for that proton?
To demonstrate that I'm not cherry picking. We see Einstein repeatedly telling us the speed of light is variable.

Plus I've already shown you the 1920 Leyden Address where Einstein talks of the aether of General Relativity.

I politely decline on the grounds that such a laborious exercise is unnecessary in the light of Einstein's description of a gravitational field as inhomogeneous space, along with our current knowledge of the expansion of the universe. Space expands between the galaxies, not within. The result is inhomogeneous space, and that's a gravitational field with no causative matter.
It is at odds with Einstein, who described the central concentration of energy tied up in as the matter of a planet causing a conditioning of the surrounding space described via a non-constant gμv which causes a variable speed of light that then causes the curvilinear motion that is described as curved spacetime. I've paraphrased, but read the original material, and you will find that I am correct.
No, I'm afraid it isn't. What's conceptually more fundamental relates to what we actually observe. We don't observe time passing, our seconds are defined using the motion of light. Thus when our second changes, it's because the rate of motion of light has changed.

See for example http://en.wikipedia.org/wiki/Variable_speed_of_light and http://arxiv.org/PS_cache/arxiv/pdf/0705/0705.4507v1.pdf where Magueijo and Moffat responded to Ellis. Its constancy has become a tautology.

I've given you ample Einstein quotes PhysBang, enough to demonstrate that I'm clearly not cherry-picking, and the hoary old "out of context" does not undo what Einstein actually said.
Here's the deal re dark matter, as simply as I can put it: it's energy that causes gravity, not matter. Matter only causes gravity because of the energy content. Einstein told us that a gravitational field has energy, and that a gravitational field is a region of inhomogeneous space. Now take a region of homogeneous space and divide it into cubes. Now decrease the energy-density of all of the cubes bar the one in the centre. The result? An energy-density gradient all around it. A gravitational field. But try as you might, when you look in that central cube, there's not a single speculative WIMP, there's no dark matter there. Because the dark matter you're looking for, is space itself. It's dark, it has energy, it isn't moving with respect to you, and E=mc2.
My gedanken about the single proton should be enormously important for anyone who thinks about it's meaning. THE EXPANDING ELECTRIC FIELD OF THE PROTON IS THE AETHER OF SPACE . When all the electrons and protons were created their expanding electric fields created space at C.
