marcin replied to the thread Both spatially and temporally flat universe expansion caused by the decrease of CMB energy leads straight to CCC.@Gibsense I added the question.

marcin posted the thread Both spatially and temporally flat universe expansion caused by the decrease of CMB energy leads straight to CCC in Cosmology.I thought I couldn't post it as text because of the amount of links, but after removing 95% of them I had the same problem, so I'm...

That makes sense to me. Maybe energy density can be linked to shape but will park that for now. Whatever you have cheered me up!

marcin replied to the thread Request for permission to share a post from astronomy.stackexchange.com.I hope you can see it now. Λ⋅g_μν must be equal to κ⋅T_μν with the CMB radiation energy density in T_μν, so Λ⋅g_00 must be equal to...
