Does anyone have an equasion for the Entropy of the Universe?
Barring my computation, please provide your best equasion for cross-verification 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.
T_i = 3000 K CBR photo-transparency temperature
T_f = 2.725 K CBR temperature
r_i = 7*10^5 Ly CBR photo-transparency range
r_f = \frac{c}{H_o} = 1.761*10^{10} Ly Universe range
Classical entropy equasion for spherical universe containing an ideal gas:
\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)
Ho = Hubble Constant
\Delta S_u = 3.230*10^{-22} J*K^{-1}
Does anyone have more accurate values?
