“Avoiding Boltzmann Brain domination in holographic dark energy models"?

03 March 2018 1 8K Report

In this article (https://www.sciencedirect.com/science/article/pii/S0370269315006760) it is proposed a model of dark energy invoking holography where Boltzmann brains do not dominate in that universe, so the Boltzmann paradox disappears.But what does it mean with "avoiding Boltzmann brain domination"? Does it mean that although Boltzmann brains would exist in these models there would be more "natural/biological" brains than Boltzmann brains?And what is the exact function of holography in this model? Could it be done in non holography models?
