There is no such thing as non-baryonic dark matter gravitationally bound to matter. Matter moves through non-baryonic dark matter. Matter displaces non-baryonic dark matter.
Non-baryonic dark matter and aether are the same side of the same coin.
Non-baryonic dark matter and aether are different labels for the same thing. Non-baryonic dark matter and aether are labels for the material which physically occupies three dimensional space unoccupied by matter.
Non-baryonic dark matter
is aether.
Aether has mass. Aether physically occupies three dimensional space unoccupied by matter. Aether is physically displaced by matter.
Displaced aether exerts force toward matter. This force is gravity.
A moving particle has an associated aether displacement wave.
Curved spacetime is displaced aether.
Einstein was most correct when as a teenager he stated the following.
"Einstein's 'First Paper'"
http://www.worldscibooks.com/etextbook/4454/4454_chap1.pdf
"The velocity of a wave is proportional to the square root of the elastic forces which cause [its] propagation, and inversely proportional to the mass of the aether moved by these forces."
The above more correctly stated as the following.
The velocity of a wave is proportional to the square root of the elastic forces which cause its propagation, and inversely proportional to the mass of the aether displaced by these forces.
What waves in a double slit experiment is non-baryonic dark matter.
What waves in a double slit experiment is the aether.
A photon is either a particle which has an associated external non-baryonic displacement wave or a photon is a 'particle' which consists of a very small region of the non-baryonic displacement wave itself.
A photon is either a particle which has an associated external aether displacement wave or a photon is a 'particle' which consists of a very small region of the aether displacement wave itself.
Either way, the photon 'particle' enters and exits a single slit in a double slit experiment and it is the associated
physical wave which enters and exits both.
