The diagram comes from according to the principle of the anharmonic oscillator with the particle that oscillates between singularity and correlated matter. Between two is the flow of the particle which is only the quantum vacuum. Dark matter is only an addition of the convergence of the quantum vacuum at a point (an area). The density of dark matter is proportional to the convergence of space towards this singularity. Dark matter is then only an addition of all the quantum vacuum space to a smaller area.
