Thinking about accelerated observers, one can in principle locate holographic screens everywhere in space?

Emergence of holographic direction is accompanied by redshifts and coarse-graining procedure?

Verlinde is assuming that the physics of a region is actually derived from physics on a surface, or "screen", bordering that region. Well, it's a model. He's hoping that gravity falls out of this picture like the extra space dimension does.

This paper has been copiously discussed online.

Sabine Hossenfelder has a set of notes that may help you make sense of the paper.

https://arxiv.org/pdf/2503.09804 From the abstract: ... Our derivation uses both EE and the Newtonian approximation of EE in Part I, to describe semi-classically in Part II the advection of DM, created at the level of the universe, into galaxies and clusters thereof. This advection happens proportional with their own classically generated gravitational field g, due to self-interaction of the gravitational field. It is based on the universal formula ρD =λgg′2 for the densityρ D of DM...
Many of us have heard of "twistors", arguably Roger Penrose's biggest contribution to theoretical physics. Twistor space is a space which maps nonlocally onto physical space-time; in particular, lightlike structures in space-time, like null lines and light cones, become much more "local" in twistor space. For various reasons, Penrose thought that twistor space was possibly a more fundamental arena for theoretical physics than space-time, and for many years he and a hardy band of mostly...
