First test of new theory of gravity

And results published in a journal from Oxford: http://mnras.oxfordjournals.org/content/early/2016/12/09/mnr...
So that's a good sign. Can't say much more than that though, since my knowledge of the field is minimal.
His theory is described in this paper: https://arxiv.org/pdf/1001.0785v1.pdf
And the Wikipedia article about it is here: 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-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.
