Dark Energy & QCD: Federico Urban & Ariel Zhitnitsky's Solution?

Click For Summary
SUMMARY

Federico Urban and Ariel Zhitnitsky's paper, "The QCD Nature of Dark Energy," proposes a mechanism for generating dark energy through the effects of Hubble expansion on the QCD vacuum. This model claims to produce specific predictions regarding the magnitude and time dependence of dark energy, making it a testable hypothesis in the near future. Despite skepticism about the viability of such ideas, the paper's predictions warrant further investigation.

PREREQUISITES
  • Understanding of Quantum Chromodynamics (QCD)
  • Familiarity with cosmological concepts, particularly dark energy
  • Knowledge of Hubble expansion and its implications

Have you seen this paper, Federico Urban and Ariel Zhitnitsky, "The QCD Nature of Dark Energy", http://lanl.arxiv.org/abs/0909.2684", They claim can generate approximately the right amount of dark energy in the universe, just from the effect of the normal Hubble expansion upon the QCD vacuum. Could this be the solution of dark energy?

Without reading much into it, let me first state that these sorts of ideas pop up all over the place. They're nearly always wrong. So, without looking into it in detail, my first impression is that it's unlikely.

That said, this model for dark energy does appear to produce some very specific predictions of both the magnitude and time dependence of dark energy. Therefore it should be imminently testable, if not now, then in the next few years.
