Comment on 'New perspective on thermodynamics of spacetime: The emergence of unimodular gravity and the equivalence of entropies'
Abstract
In this comment on the article by Alonso-Serrano and Liska (arXiv: 2008.04805) a formal resemblance between their expression of curvature scale and the scale dependent on the matter energy-momentum ambiguity of Finkelstein et al (JMP, 2001) is pointed out. Physical significance of this observation is also discussed.
