SUMMARY

The discussion centers on the evolving dark energy concept, referencing key papers such as Peebles et al.'s work on the cosmological constant and dark energy, and the model-independent evidence presented by Sahni et al. (2014) and corroborated by Ding et al. (2015). The findings suggest statistical uncertainties in the analysis of dark energy evolution, which the original poster does not consider sufficient evidence for its existence. The conversation highlights the importance of ongoing research in understanding dark energy dynamics.

In the course of brushing up on my dark energy, https://arxiv.org/abs/astro-ph/0207347, The Cosmological Constant and Dark Energy, I noticed Peebles, et al, raised the possibility of evolving dark energy. Curious, I elected to do some further checking and turned up this rather startling claim; https://arxiv.org/abs/1406.2209, Model independent evidence for dark energy evolution from Baryon Acoustic Oscillations. As seems all too often, I was quite surprised I had not noticed this sooner and was further surprised to learn it has apparently since been corroborated; https://arxiv.org/abs/1503.04923, Is there evidence for dark energy evolution? Just how big a deal is this, or am I just living under a rock?

As I read it, there are still some statistical uncertainties in the analysis done by Sahni et. al (2014), as apparently collaborated by Ding et. al (2015), summarized in the latter's para. 3.

I would not take this as sufficient evidence for dark energy evolution.
