So answer my question.
There's multiple possible answers, among which are:
1) Einstein was wrong (he wasn't infallible you know).
2) At what stage did he state that, and did he later change his mind?
A nonsensical declaration without support REMAINS a nonsensical declaration without support no matter how many times it's repeated.
One more time: WHAT EVIDENCE DO YOU HAVE?
And still waiting for your "explanation" of the disparity between observed results and your claim that it's density not mass that "causes" gravity.
Evidence?
The more mass per volume the less aether the volume contains the more aether which is displaced by the matter the more force there is exerted toward the matter by the displaced aether.
'Superfluid Is Shown To Have Property Of A Solid'
http://www.sciencedaily.com/releases/1999/07/990730072958.htm
'Northwestern University physicists have for the first time shown that superfluid helium-3 -- the lighter isotope of helium, which is a liquid that has lost all internal friction, allowing it to flow without resistance and ooze through tiny spaces that normal liquids cannot penetrate -- actually behaves like a solid in its ability to conduct sound waves. ... "Faraday's finding was the first indication that light and magnetism were related," says William Halperin, professor of physics and astronomy at Northwestern. "I wouldn't say that our discovery is of that magnitude, but it is significant as the first observation of a previously unknown mode of wave propagation in a liquid -- one that is of the type you would expect to see in a solid."'
The aether is, or behaves similar to, a frictionless superfluid with properties of a solid.
The galaxy clusters in the following article are not traveling with dark matter. There is no such thing as dark matter. The galaxy clusters are moving through the aether. The galaxy clusters displace the aether.
'Hubble Finds Ghostly Ring of Dark Matter'
http://www.nasa.gov/mission_pages/hubble/news/dark_matter_ring_feature.html
"Astronomers using NASA's Hubble Space Telescope got a first-hand view of how dark matter behaves during a titanic collision between two galaxy clusters. The wreck created a ripple of dark mater, which is somewhat similar to a ripple formed in a pond when a rock hits the water."
The 'pond' consists of aether. The moving 'particles' are the galaxy clusters. The 'ripple' is a gravitational wave. The 'ripple' is an aether displacement wave.
The above is physical evidence of a moving 'particle' having an associated aether displacement wave.
In a double slit experiment, the particle travels a single path and enters and exits a single slit. It is the associated aether displacement wave which enters and exits both slits. The aether displacement wave creates wave interference upon exiting the slits. As the particle exits a single slit, it is this interference which alters the direction the particle travels. Detecting the particle causes a loss of coherence of the associated aether displacement wave, there is no wave interference, and the direction the particle travels is not altered.
Aether has mass. Aether physically occupies three dimensional space. Aether is physically displaced by matter. Aether is not at rest when displaced. Displaced aether exerts force toward matter.
Aether displacement explains why the shape of the Milky Way's 'dark matter' is in the shape of a squished beach ball.
'Dark Halo Around Our Galaxy Looks Like Squished Beach Ball'
http://www.space.com/7746-dark-halo-galaxy-squished-beach-ball.html
"Dark matter seems to shroud the remaining visible matter in giant spheres called haloes."
The Milky Way's halo is displaced aether.
"But the new study found that the Milky Way's halo isn't exactly spherical, but squished. In fact, its beach-ball form is flattened in a surprising direction perpendicular to the galaxy's visible, pancake-shaped spiral disk."
All of the aether displaced by the Milky Way matter exerts force toward the matter. The force exerted toward the matter by the aether displaced perpendicular to the plane of the galaxy's spiral disk offset. It is the aether which is displaced outward relative to the plane of the spiral disk which exerts force toward the center of the galaxy. This forces the matter closer together which results in the displaced aether looking like a squished beach ball.
Matter does not move with dark matter. Matter moves through the aether.
'Offset between dark matter and ordinary matter: evidence from a sample of 38 lensing clusters of galaxies'
http://onlinelibrary.wiley.com/doi/10.1111/j.1365-2966.2010.16739.x/abstract
"We compile a sample of 38 galaxy clusters which have both X-ray and strong lensing observations, and study for each cluster the projected offset between the dominant component of baryonic matter centre (measured by X-rays) and the gravitational centre (measured by strong lensing). Among the total sample, 45 per cent clusters have offsets [greater than]10 arcsec. The [greater than]10 arcsec separations are significant, considering the arcsecond precision in the measurement of the lensing/X-ray centres. This suggests that it might be a common phenomenon in unrelaxed galaxy clusters that gravitational field is separated spatially from the dominant component of baryonic matter. It also has consequences for lensing models of unrelaxed clusters since the gas mass distribution may differ from the dark matter distribution and give perturbations to the modelling. Such offsets can be used as a statistical tool for comparison with the results of Lambda cold dark matter ( CDM) simulations and to test the modified dynamics."
The offset is due to the galaxy clusters moving through the aether. The analogy is a submarine moving through the water. You are under water. Two miles away from you are many lights. Moving between you and the lights one mile away is a submarine. The submarine displaces the water. The state of displacement of the water causes the center of the lensing of the light propagating through the water to be offset from the center of the submarine itself. The offset between the center of the lensing of the light propagating through the water displaced by the submarine and the center of the submarine itself is going to remain the same as the submarine moves through the water. The submarine continually displaces different regions of the water. The state of the water connected to and neighboring the submarine remains the same as the submarine moves through the water even though it is not the same water the submarine continually displaces. This is what is occurring physically in nature as the galaxy clusters move through the aether.
The Universe is, or the local Universe we exist in is in, a jet.
'Mysterious Cosmic 'Dark Flow' Tracked Deeper into Universe'
http://www.nasa.gov/centers/goddard/news/releases/2010/10-023.html
'The clusters appear to be moving along a line extending from our solar system toward Centaurus/Hydra, but the direction of this motion is less certain. Evidence indicates that the clusters are headed outward along this path, away from Earth, but the team cannot yet rule out the opposite flow. "We detect motion along this axis, but right now our data cannot state as strongly as we'd like whether the clusters are coming or going," Kashlinsky said.'
The clusters are headed along this path because the Universe is, or the local Universe we exist in is, a jet. Analogous to the polar jet of a black hole.
The following is an image analogous of the Universal jet:
http://aether.lbl.gov/image_all.html
The reason for the 'expansion' of the universe is the continual emission of aether into the Universal jet. Three dimensional space associated with the Universe itself is not expanding. What we see in our telescopes is the matter associated with the Universe moving outward and away from the Universal jet emission point. In the image above, '1st Stars' is where aether condenses into matter.
The following is an image analogous of the Universe, or the local Universe, we exist in:
http://www.astro.ucla.edu/planetarium/graphics/st_images/BlackHole.jpg
Dark energy is the change in state of the aether emitted into and propagating through the Universal jet.
It's not the Big Bang. It's the Big Ongoing.
Einstein's definition of motion as applied to the ether is defined throughout the following article as the ether does not consist of individual particles which can be separately tracked through time.
I interpret Einstein's definition of motion as applied to the ether as it can not be known if ether consists of particles or not.
'Ether and the Theory of Relativity - Albert Einstein'
http://www.tu-harburg.de/rzt/rzt/it/Ether.html
"if, in fact nothing else whatever were observable than the shape of the space occupied by the water as it varies in time, we should have no ground for the assumption that water consists of movable particles. But all the same we could characterise it as a medium."
"There may be supposed to be extended physical objects to which the idea of motion cannot be applied. They may not be thought of as consisting of particles which allow themselves to be separately tracked through time."
"The special theory of relativity forbids us to assume the ether to consist of particles observable through time, but the hypothesis of ether in itself is not in conflict with the special theory of relativity."
"According to the general theory of relativity space without ether is unthinkable;...But this ether may not be thought of as endowed with the quality characteristic of ponderable media, as consisting of parts which may be tracked through time. The idea of motion may not be applied to it."
Every time Einstein mentions motion as applied to the ether it is defined as the ether does not consist of individual particles which can be separately tracked through time. This is different than Einstein's definition of mobility as applied to the ether.
The ether of general relativity is mobile.
"It may be added that the whole change in the conception of the ether which the special theory of relativity brought about, consisted in taking away from the ether its last mechanical quality, namely, its immobility."
"the state of the [ether] is at every place determined by connections with the matter and the state of the ether in neighbouring places, ... disregarding the causes which condition its state."
The state of the ether as determined by its connections with the matter and the state of the ether in neighboring places is the state of displacement of the ether.

"Since according to our present conceptions the elementary particles of matter are also, in their essence, nothing else than condensations of the electromagnetic field"
The electromagnetic field is a state of aether.
Matter is condensations of aether.
DOES THE INERTIA OF A BODY DEPEND UPON ITS ENERGY-CONTENT?' A. EINSTEIN
http://www.fourmilab.ch/etexts/einstein/E_mc2/e_mc2.pdf
"If a body gives off the energy L in the form of radiation, its mass diminishes by L/c2."
The mass of the body does diminish; however, the matter which no longer exists as part of the body has not vanished. It still exists, as aether.
Matter evaporates into aether.
As matter converts to aether it expands in three dimensional space. The physical effects this transition has on the neighboring aether and matter is energy.
Mass is conserved. Energy is conserved.
A change in state of that which has mass is energy.
Force exerted toward matter by aether displaced by matter is gravity.
Your turn. Explain what occurs physically in nature in a double slit experiment.
