Does anyone have an equasion for the Entropy of the Universe? Barring my computation, please provide your best equasion for crossverification with a numerical entropic solution in (J*K^1) SI units. I attempted to locate a solution on the internet, however only located entropy for various particles and black holes. Anyone interested in examining some black hole entropy equasions may click the reference provided. These equasions represent my classical approach. [tex]T_i = 3000 K[/tex] CBR phototransparency temperature [tex]T_f = 2.725 K[/tex] CBR temperature [tex]r_i = 7*10^5 Ly[/tex] CBR phototransparency range [tex]r_f = \frac{c}{H_o} = 1.761*10^{10} Ly[/tex] Universe range Classical entropy equasion for spherical universe containing an ideal gas: [tex]\Delta S_u = K_b \left( ln \frac{T_f}{T_i} + ln \left( \frac{r_f}{r_i} \right)^3 \right) = K_b \left( ln \frac{T_f}{T_i} + ln \left( \frac{c}{H_o r_i} \right)^3 \right)[/tex] H_{o} = Hubble Constant [tex]\Delta S_u = 3.230*10^{22} J*K^{1}[/tex] Does anyone have more accurate values?

You would have to accomodate every instant..instanton.. and every Futurama?, if only just to get some approximation of what you are counting!.
