Let’s consider the possibility that the same phenomenon that is responsible for dark energy is responsible for dark matter. The phenomenon I am referring to is the change in the fluctuation in space.  Fluctuation of spaces, when phased, create an equal and opposite change in dimension.  Phasing creates a positive change in dimension and a negative change in dimension. The negative change in dimension has a gravitational component and creates the effect we recognize as dark matter. The positive change in dimension is the effect we recognize as dark energy.  So why do we have this expansion of the universe when there is a component with a gravitational increase and a component that is just as it creates a positive change in dimension pushing space outward? The reason why the gravitational component does not overcome the expansion of space is that the gravitational component does not interact, or interacts very weakly, with the positive change in the shape of space. The gravitational component  of the negative change in dimension does, however, interact with mass. The gravitational effect of the  negative change in dimension  which is a function of the phased fluctuation of dimension, interacts with existing mass.  The expansion of space is a function of the positive change in dimension which is also a function of the phased fluctuation of dimension. As space expands, the area of space in which fluctuations of space  occurs expands, thus more fluctuations of space phase, thus the expansion of space  accelerates.
