Notes Concerning "On the Origin of Gravity and the Laws of Newton" by E. Verlinde (arXiv:1001.0785)

TL;DR

This paper clarifies that some equations used by Verlinde as starting points for deriving gravity thermodynamically are actually derived from an earlier microscopic spacetime model, providing context and validation.

Contribution

It demonstrates that Verlinde's key equations are consequences of a pre-existing microscopic spacetime model, not independent postulates.

Findings

Verlinde's equations follow from the microscopic model

The paper connects thermodynamic derivations to underlying spacetime structure

Provides historical context for the equations used in emergent gravity theories

Abstract

We point out that certain equations which, in a very recent paper written by E. Verlinde, are postulated as a starting point for a thermodynamical derivation of classical gravity, are actually consequences of a specific microscopic model of spacetime, which has been published earlier.
