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?
