LQC Lambda-CDM model bounce radius

AI Thread Summary
The discussion focuses on the calculations related to the Lambda-CDM model and Loop Quantum Cosmology (LQC) to determine the bounce radius of the universe. Key equations are presented, including the total energy in the universe, which is calculated as approximately 3.764 x 10^73 joules. The observable universe radius is defined as 4.399 x 10^26 meters, while the LQC maximum energy density parameter is noted as 0.41. The derived LQC bounce radius is calculated to be 5.829 x 10^-14 meters, with an alternative bounce radius based on Planck energy density yielding 4.330 x 10^-14 meters. These findings contribute to understanding the universe's mass-energy equivalence within the context of current cosmological models.

These are my equations for the total Universe_mass-energy equivalence based upon the Lambda-CDM model parameters and the Hubble Space Telescope (HST) and WMAP observational parameters and the observable Universe radius in Systeme International units.

I attempted to collapse the Lambda-CDM model parameter dimensions using the maximum LQC bounce density to determine the bounce radius.

Observable Universe radius:
R_u = 4.399 \cdot 10^{26} \; \text{m}
Lambda-CDM stellar Baryon density parameter:
\Omega_s = 0.005
Hubble Space Telescope observable stellar number:
dN_s = 10^{22}
Hubble Space Telescope observable stellar volume:
dV_s = 3.3871 \cdot 10^{78} \; \text{m}^3 \; \; \; (4 \cdot 10^{30} \; \text{ly}^3)
Solar mass:
M_{\odot} = 1.9891 \cdot 10^{30} \; \text{kg}

Planck energy density:
\boxed{\rho_p = \frac{E_p}{V_p} = \frac{3 c^7}{4 \pi \hbar G^2}}

\boxed{\rho_p = 1.106 \cdot 10^{113} \; \frac{\text{j}}{\text{m}^3}}

Universe_mass-energy equivalence total energy:
\boxed{E_t = \frac{4 \pi c^2 M_{\odot}}{3 \Omega_s} \left( \frac{dN_s}{dV_s} \right) R_u^3}

Total amount of energy in the Universe:
\boxed{E_t = 3.764 \cdot 10^{73} \; \text{j}}

Universe total energy density:
\rho_u = \frac{E_t}{V_u} = \frac{3 E_t}{4 \pi R_u^3} = \frac{M_{\odot} c^2}{\Omega_s} \left( \frac{dN_s}{dV_s} \right)

LQC maximum energy density parameter: (ref. 10 p. 73 (5.7))
\boxed{\Omega_{LQC} = \frac{\rho_{\text{max}}}{\rho_p} = \frac{\hbar G}{2 \gamma^2 \lambda^2 c^7} = 0.41}

Universe total energy density equivalent to LQC maximum energy density:
\rho_u = \rho_{\text{max}}

Integration via substitution:
\frac{3 E_t}{4 \pi R_{LQC}^3} = \Omega_{LQC} \rho_p

Universe LQC Lambda-CDM bounce radius:
\boxed{R_{LQC} = \left( \frac{3 E_t}{4 \pi \Omega_{LQC} \rho_p} \right)^{\frac{1}{3}}}

\boxed{R_{LQC} = 5.829 \cdot 10^{-14} \; \text{m}}

May please Check with Maattihias Bartelmann of MPI for Astrophysics Garching Germany.

I have his paper with me on this subject,and found promising like yours,but I have to compare.
 


Universe total energy density equivalent to Planck energy density:
\rho_u = \rho_{p}

Integration via substitution:
\frac{3 E_t}{4 \pi R_{1}^3} = \rho_p

Universe Planck energy density bounce radius:
\boxed{R_{1} = \left( \frac{3 E_t}{4 \pi \rho_p} \right)^{\frac{1}{3}}}

\boxed{R_{1} = 4.330 \cdot 10^{-14} \; \text{m}}

https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
Why was the Hubble constant assumed to be decreasing and slowing down (decelerating) the expansion rate of the Universe, while at the same time Dark Energy is presumably accelerating the expansion? And to thicken the plot. recent news from NASA indicates that the Hubble constant is now increasing. Can you clarify this enigma? Also., if the Hubble constant eventually decreases, why is there a lower limit to its value?
