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.
