First, here is a link that is not hidden behind a paywall: https://arxiv.org/pdf/1607.04878v2.pdf > there is substantial evidence supporting a holographic explanation of the universe—in fact, as much as there is for the traditional explanation of these irregularities using the theory of cosmic inflation. This is a bit misleading, especially the phrase "substantial evidence". I bet that the authors of the paper would not have used this phrasing. From the paper: > We emphasise that the application of holography to cosmology is conjectural, the theoretical validity of such dualities is still…

The abstract of the paper about which the article reports is less dramatic: https://arxiv.org/abs/1607.04878 "By comparing the Bayesian evidence for the models, we find that ΛCDM does a better job globally, while the holographic models provide a (marginally) better fit to data without very low multipoles." So the non-holographic model seems to be better globally even according to the paper. https://en.wikipedia.org/wiki/Lambda-CDM_model If the further research proves that holographic models are better, it's good too, let the best wins. But at the moment it still looks to be too early to…
