I need the theoretical energy density of inflation for my story. I seem to recall it as an enormous 1095 ergs per cubic centimeter.

You're right. Maybe it's a typo for mass density equivalent, using e=mc2?Hornbein said:A septillion.
Oops, my bad. I misinterpreted Wright. I failed to notice that he represented energy density as g/cc, not ergs/cc. Using e=mc2, I get 1091-92 ergs/cc. Closer to the value in the figure above.chasrob said:Uh, oh. Ned Wright, https://www.astro.ucla.edu/~wright/cosmo_constant.html says 1071 g/cc. Quite a difference. Ten trillion or so?

The theoretical energy density of inflation is the amount of energy per unit volume that is thought to have driven the rapid expansion of the universe during the early moments of the Big Bang. It is a key concept in inflationary cosmology, which proposes that the universe underwent a brief period of exponential expansion shortly after the Big Bang.
The theoretical energy density of inflation is calculated using mathematical models and equations that describe the behavior of the universe during the inflationary period. These models take into account factors such as the rate of expansion, the energy content of the universe, and the properties of the inflation field.
The theoretical energy density of inflation is significant because it helps to explain several key observations about the universe, such as its overall flatness and the uniformity of the cosmic microwave background radiation. It also provides a potential solution to the horizon problem and the flatness problem in cosmology.
The theoretical energy density of inflation is often compared to dark energy, which is a mysterious force thought to be responsible for the current accelerating expansion of the universe. While both concepts involve energy density, they are distinct phenomena and are thought to have operated at different times and scales in the history of the universe.
The theoretical energy density of inflation is a widely accepted concept in cosmology, but it is still considered a theoretical framework and has not yet been conclusively proven. However, it is supported by a large body of evidence and is consistent with many observations of the universe, making it a promising avenue for further research and study.
