Comment on 'Large-scale non-locality in "doubly special relativity" with an energy-dependent speed of light'

TL;DR

This paper critiques recent claims about non-locality in doubly special relativity, highlighting that some assumptions made are inconsistent with established principles of the theory and Planck-scale physics.

Contribution

It clarifies misconceptions by analyzing the assumptions behind recent results on non-locality in doubly special relativity.

Findings

Some recent results are based on assumptions conflicting with fundamental properties of DSR.

The critique emphasizes the importance of consistent assumptions in theoretical physics.

Highlights the need for careful analysis in Planck-scale physics models.

Abstract

We show that some of the recent results reported in gr-qc/0308049 are based on assumptions which are in contrast with general properties of ``Doubly Special Relativity'' and/or with Planck-scale physics models.
