I How to Independently Determine the Proportion of Dark Energy Density?

AI Thread Summary
Determining the proportion of dark energy density independently from the standard method of 1 - (Ωmatter + Ωdark matter) is questioned in the discussion. The concept of "proportion of dark energy" is clarified, emphasizing that its density is constant. The reference to M. Kowalski et al. suggests that improved cosmological constraints could provide insights. The discussion hints at the assumption of ΩΛ as a key factor in understanding dark energy. Overall, the conversation revolves around the complexities of measuring dark energy density in cosmology.

Is there a way to independently determine the proportion of dark energy density to total energy density of the universe apart from using 1 -(Ωmatter+Ωdark matter )?

What do you mean by saying a "proportion of dark energy"? It's density is constant and a tenth of it too.

From what was stated, I assume ΩΛ.
 

Thread 'Matter density right after the decoupling'

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##.

Thread 'Hubble Constant, Dark Energy and the Expanding Universe'

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?
