Observable Universe mass...
This is my equation for the observable Universe mass, based upon the Cosmic Energy Inventory (CEI) parameters and the Hubble Space Telescope (HST) parameters in (SI) units. Universe observable parameters: Universe total observable radius: [math]R_u = 4.408 \cdot 10^{26} \; \text{m} \; \; \; (46.6 \cdot 10^{9} \; \text{ly})[/math] CEI stellar Baryon density: [math]\Omega_s = 0.00205[/math] HST observable stellar number: [math]N_s = 10^{22}[/math] Solar mass: [math]M_{\odot} = 1.989 \cdot 10^
WMAP satellite cosmological parameters at photon decoupling time: (ref. 1)
[math]\Omega_{\gamma , t} = 0.15[/math]
[math]\Omega_{\nu , t} = 0.10[/math]
[math]\Omega_{\Lambda , t} \neq 0[/math]
Photon radiation constant: (ref. 7, p. 42, eq. 205)
[math]\alpha_{\gamma} = \frac{\pi^2 k_B^4}{15 (\hbar c)^3}[/math]
Observable Universe cosmic background photon radiation temperature at present time:
[math]T_{\gamma} = 2.72548 \; \text{K}[/math]
