Stellar heated gas and dust has a universe total entropy/information content of ~10^86 bits. At typical temperatures ~10^7 the equivalent N kB T ln(2) information energy ~10^70 J is comparable to the mc2 of the universe's ~10^53 kg of baryons. At low red-shifts, z<1.35 this dark energy contribution provides a near constant energy density, with an equation of state parameter, w=-1.03±0.05, effectively emulating a cosmological constant to within 1.8% in Hubble parameter, H(a).

... 5, the information energy contribution was phantom, w=-1.82±0.08. This dark energy differs from the cosmological constant by △w0= -0.03±0.05 and △wa= -0.79±0.08, sufficient to account for the value of the 'Hubble Tension' between early and late universe H0 values. An information energy model will fit most observations as well as Ʌ, and also resolve Hubble tension and cosmological coincidence problems. Furthermore, information energy could also account for many effects previously attributed to dark matter.
