Cosmological Expansion: Exploring Expansion Force Beyond Big Bang Theory

In summary: Overall, more research and evidence is needed to fully understand the expansion of the universe. In summary, the conversation discusses a speculation about the expansion force of the universe, specifically focusing on the role of photons and plasma in the early stages after the Big Bang. However, it is important to note that current theories suggest that dark energy is the main driving force behind the expansion of the universe.

At the risk of further muddying up the epicycling, let me offer a wild speculation concerning the expansion force.

At the close of the infaltion epoch assumed by its advocates to have been at 10^-35 (superscript negative 35) seconds after time zero of the big bang, the universe is believed, again by big bang advocates, to have been no larger than the volume of a sphere of one light year radius and to consist of a very dense collection of photons and plasma. Ninety-five to ninety-seven per cent of this energetic soup is energy at the very high gamma energy level due to matter anti-matter particle annihilations to generate the current matter configuration of the universe. The expansion rate outward from this primordial one light year radius after 10^-35 seconds is much slower than light speed (probably ?) allowing this gamma level photon energy to supply an outward pressure on spacetime in opposition to the very intense (orders of magnitude larger than current) gravitational field. Also, due to the plasma state of the matter existing until the transparency state was achieved (release of what is now observed as the cosmic background radiation) and the likely equidistribution of kinetic energy across the electrons and protons, the electrons would have outraced the protons generating an inner sphere of mutually repelling protons surrounded by a spherical shell of mutually repelling electrons. (I'm not sure whether the lifespan of any neutrons that come and go during this phase allows them to be worthy of consideration, nor, if so, how to consider them.) Also the photons have outraced the electrons (most escaping prior to the forming of the proton sphere and the electron shell and their respective opacities).

It seems reasonable to assume that most of the high energy matter-antimatter gammas (MAGs) have very quickly reached the space-time horizon since they travel faster than the post inflation rate of space-time expansion and faster than the electron shell. By this time they will be "pairforming" and annihilating at whatever rates the laws of physics allow (beyong my ability to speculate quantitatively) while bouncing back and forth between the horizon and the electron shell all within an unimaginably intense electric and magnetic field environment generated by the churning electron shell and the proton sphere.

How could space-time avoid being stretched? And then momentum takes over.

Any merit here?

The speculation presented here has some merit and could be further explored to see how it fits in with the Big Bang theory. However, it is important to note that the expansion of the universe is currently believed to be driven by dark energy, rather than photons and plasma. Dark energy is a hypothetical form of energy that is postulated to exist in the vacuum of space and exerts a repulsive force on matter, driving the acceleration of the universe's expansion. As such, the speculation presented here does not necessarily provide an explanation for the expansion force of the universe.
 

1. What is cosmological expansion?

Cosmological expansion is the observed phenomenon in which the space between galaxies is increasing over time. This expansion is believed to have started with the Big Bang and is the main driving force behind the evolution of the universe.

2. How is cosmological expansion measured?

Cosmological expansion is measured through the use of redshift, which is a change in the wavelength of light coming from distant galaxies. This change in wavelength is caused by the expansion of space and can be measured using spectroscopy.

3. Is the rate of cosmological expansion constant?

No, the rate of cosmological expansion is not constant. It has been observed that the expansion rate of the universe is actually increasing over time, meaning that galaxies are moving away from each other at a faster rate.

4. What is the role of dark energy in cosmological expansion?

Dark energy is believed to be the driving force behind the accelerating expansion of the universe. It is a mysterious form of energy that makes up about 70% of the total energy in the universe and its exact nature is still not fully understood by scientists.

5. Can cosmological expansion be reversed?

Based on current scientific understanding, it is unlikely that cosmological expansion can be reversed. The expansion of the universe is driven by dark energy, and there is no known force that can counteract its effects. However, it is still an area of ongoing research and our understanding may change in the future.
