The anomalous galaxy velocities are due to an unknown variable, but what is the variable?
The variable is atomic mass. Allow me to explain.
Think of atomic mass as being a product of atomic energies. Consider the possibility that because time dilation is an account of variable atomic activity, that variable atomic activity is an account of variable atomic energy.
Variable atomic energy = variable atomic mass
Because variable atomic energy/mass corresponds to the gravitational fields, it is a mathematical testable hypothesis. It is entirely falsifiable. Variable atomic mass alters the mass distribution of galaxies and galaxy groups, and therefore the gravitational potential.
Furthermore, the reason atomic energy/mass is variable and corresponds to the gravitational environment of space is because atoms acquire the energy from space needed to generate atomic energy/activity/mass. Analogous to how photosynthetic life acquires energy from the sun to drive biological processes. And here's a bombshell. Life evolved structures and processes optimized for efficient energy capture and utilization, and after billions of years of Darwinian evolution life results in a system of units comprised of a nucleus shrouded within a shell and the capacity to bond with each other and build bodies. And Atomic physics shares that same theme for the same reason. Atomic physics and cellular biology are different systems, but their shared structural and behavioral theme is a result of co-vergent evolution, a result of optimization for efficient energy capture.
Atoms are extremely special little building blocks. Think about how complex, finely tuned and interactive they are, how biology makes full use of atomic properties and showcases how extremely specialized building blocks atomic units are. Chance creation is not a suitable explanation for the creation of a system as interesting as this. And there's no designer. However, we know of a process with the capacity to generate a system of high complexity, and we have its precedence having generated another system of precisely the same structural and behavioral theme.
Atoms are made of energy fields, but why do these energy fields conspire to build such a complex and interactive system such as physics? Darwinian evolution is the answer. Darwinian Universal.
The big bang theory has little explanatory power. Darwinian evolution is rich in explanation, and the Darwinian cosmology that I have begun teasing out is just as rich in explanation as it is in the telling of the origin of life.
