inflation and dark energy
and dark energy explained.
The big bang theory of the universe is now established as the most probable origin of the universe. However, all current computer models of universe formation require a period of inflation, to produce an output that approximates the known universe. For those readers without a background in cosmology, the idea of inflation is; That following the big bang the universe was expanding and forming. Then without a known cause, the rate of that expansion increased drastically, rapidly increasing the size of the universe. Just as inexplicably, the expansion had to suddenly slow down to the rate that allows for the formation of stars, and galaxies. Dark energy is the name given to the unexplained force that is causing the expansion of the universe to accelerate, as it is being observed now.
The process that explains inflation.
The profound implications of this process I will not deal with here. For now, I would ask that we limit the explanation to the question of whether this explanation is a good fit for cosmological inflation, at the level of visualization.
Assume that instead of creating one universe, that the big bang created very many, each with its own set of constants. Many would not be stable and would cease to exist. Some would be dominated by attractive forces. Forming dense but stable universes. In others, the attractive forces will be insufficient to stop it from flying off towards infinity.
The second assumption needed for this explanation to work is that where two of these universes overlap, the area of the overlap develops stable composite values.
Visualizing the expansion of the universe with these assumptions in place. The universe initially expands as per the normal big bang model. Then adjacent supper light universes expand to overlap our universe, diluting its attractive forces and augmenting its expansive forces. This causes the expansion of our universe to accelerate in a series of steps. After a time our, now much larger, universe starts to overlap other heavier universes. But because by this time our universe has expanded to the point that it takes time for the influence of these universes to spread across our universe, there will be a disturbing/churning effect on our universe during the slowing phase of the inflation process.
The implications of this for dark energy.
The Sun converts 4 000 000 tones of mass into energy every second. This is indicative of the amount of mass lost by every star in the observable universe. This loss of mass causes a corresponding loss of gravitational attraction.
Out beyond the edge of the observable universe, at the edge of the universe as it is now, supper dense universes that will never overlap as far as the observable universe. Are adding to the gravitational attraction towards the edge.
The implications of this.
First if this is true. Then none of the so-called universal constants can be assumed to be constant, either across universal time or space.
This can not be called a theory because it does not lend its self to the experimental method.
It is a potentially useful model of cosmological inflation because as well as explaining inflation, it provides a source of perturbations to start galaxy formation.
