He's well-qualified. His background is in string theory. His theory is described in this paper: https://arxiv.org/pdf/1001.0785v1.pdf https://arxiv.org/pdf/1001.0785v1.pdf And the Wikipedia article about it is here: https://en.wikipedia.org/wiki/Entropic_gravity https://en.wikipedia.org/wiki/Entropic_gravity It's argued here that there's observational evidence against it: https://www.technologyreview.com/s/425220/experiments-show-gravity-is-not-an-emergent-phenomenon/ https://www.technologyreview.com/s/425220/experiments-show-g... I'm not familiar with the areas of physics the theory draws on. I am familiar with General Relativity, which agrees very well with observations, and (I think) makes fewer assumptions.
