The same physics stories are often repeated, almost suggesting a conspiracy to brainwash the public. Scientists have said for decades the Universe is expanding, and it seems every couple of weeks we are reminded of this.
The Aether Physics Model does suggest the Universe is continually expanding. But the APM also points out the Universe is continually contracting, such as at the centers of galaxies.
As protons bind with electrons, they produce neutrons and also force their encapsulating Aether units to fold over onto each other. Thus two Aether units occupy the same space as one Aether unit. This means that as matter becomes denser by the production of neutrons, space also becomes denser.
However, as space becomes denser adjoining Aether units are stretched to help keep space "full." This means the regions of space surrounding dense objects gets rarefied and can produce optical effects on the photons passing through it. The optical effects manifest as gravitational lensing, orbital precessing, and other Relativity effects.
As matter and space become too dense in the centers of galaxies, the space collapses and unravels while taking the matter within that space with it. Thus, entire stars disappear forever as they enter the galactic core's disintegrating vortex.
If contraction was the whole story, the Universe would shrink until there was just a small pile of matter left floating in space, which would not be dense enough to cause the unraveling of the remaining Aether.
Fortunately, due to the Casimir effect on electrons and hot/cold fusion effects on protons, new visible matter constantly generates. Along with the creation of new matter also comes the creation of new Aether units, or space.
And so it goes. The mass underlying visible matter is converted to dark matter at the centers of galaxies and then through the Casimir effect and fusion, new matter is created elsewhere in the galaxy. When visible matter becomes unraveled, its form becomes dark matter. This is because the Aether is the source of electricity and magnetism. If dark matter is not encapsulated within Aether units, then there is no visible (electromagnetic) matter.
Different regions of the Universe have varying densities of dark matter available, which may become fuel for generating new visible matter. Thus, the observations of galactic clusters would tell us that underlying the galactic cluster is a vast region of space possessing a large deposit of dark matter. Conversely, regions of space devoid of visible matter and relativistic effects must be lacking in dark matter density.
As for "dark energy," that is a misnomer. There is no such "thing" as "visible energy," let alone "dark energy." Energy is a unit of work. Energy is real as a property of matter, but it is not a material thing of itself. One cannot make something material from a substance called energy. Matter can only be built from matter. Visible matter can be built from dark matter, and it can be unraveled. But energy is only the movement of matter, and matter must possess the dimension of mass.
Many scientists are fooled into thinking dark energy is some kind of hidden light because energy is often used as a synonym for visible light. Light is electromagnetic radiation, or a manifestation of mass momentum within the fabric of Aether. Dark matter does not exist within the Aether fabric, but rather has its existence outside of the Aether. Therefore, dark matter has no electric or magnetic properties and cannot be a type of electromagnetic radiation in any form.
According to the Aether Physics Model, dark matter is properly defined and quantified as strings of mass. If the strings of mass are moving relative to the Aether, such as neutrinos being released from beta decay neutrons, then it can be said that dark matter possesses the property of energy. But it is inappropriate to describe the energy as something separate from the dark matter, itself. There is only dark matter, whether it is moving or not.
So the ever expanding and contracting Universe is driven by the continual process of visible matter converting to dark matter, and dark matter converting back to visible matter. Whether the Universe appears to be expanding or contracting depends upon where you are looking.
