Unrelated to the paper, the most satisfying (would-be) explanation of gravity I ever learned was from AdS/CFT correspondence. Basically, it says that a Conformal Field Theory in D dimension is equivalent to a theory with gravity in D+1 dimensions. In other words, the physics that describe the 2D boundary of a anti-de Sitter space corresponds to theories that describe gravity inside that 3D space. This would click well with the holographic universe theory and entirely eliminate the problem of needing to explain gravity since it would be an emergent force

But alas, our universe is more like dS space (positive curvature), not AdS (negative curvature).
