The average density of visible matter in the Universe is estimated to $3\times10^{-28}$ kg/$m^3$ and that of invisible matter about 10 times bigger, altogether corresponding to the mass of a few protons per $m^3$. This is very very small.
In the Neo-Newtonian Cosmology NNC studied in recent posts mass/matter of variable sign $\rho=\Delta\phi$ is created by the action of the Laplacian differential operator $\Delta$ on a rapidly oscillating small amplitude initial perturbation $\phi$ of a zero gravitational potential distributed over an infinite Euclidean space. Gravitational force with attraction/repulsion of mass of same/opposite sign segregates mass into regions of positive mass and negative mass which repel each other and so drives expansion.
The action the Laplacian inflates oscillations and so a very very small initial distributed perturbation of a zero gravitational potential is required to create the very small average mass density observed. It is natural to name the initial perturbation as a Small Bang apparently giving mass to matter from virtually nothing.
The Small Bang thus creates positive and negative mass/matter distributed over infinite space and it is natural to expect positive mass/matter to be visible if $\rho=\Delta\phi$ is large enough positive, and invisible else as dark matter. The expansion effect attributed to dark energy can be viewed to be the repulsive effect of negative invisible mass/matter.

Perhaps this NNC creation is continuous. Has and will go on forever?
SvaraRaderaYes, that is thinkable. Even more plausible than a single small bang…
SvaraRaderaThe Universe must be eternal. If not, we will always ask what was before e.g. The Big Bang. The NNC theory may solve this. NNC has gone on forever even if this is difficult to understand. Amazing theory.
