Doubly Special Relativity as a Limit of Gravity

TL;DR

This paper explores Doubly Special Relativity (DSR), proposing it as a flat space, semiclassical limit of gravity, and discusses its foundational postulates and potential to replace Special Relativity at ultra-high energies.

Contribution

It introduces the perspective that DSR can be derived as a limit of gravity, connecting quantum gravity concepts with modified relativistic frameworks.

Findings

DSR has two observer-independent scales: velocity and mass.

Arguments are presented supporting DSR as a limit of gravity.

The paper discusses the foundational postulates of DSR.

Abstract

Doubly Special Relativity (DSR) is a theory with two observer-independent scales, of velocity and mass, which is expected to replace Special Relativity at ultra-high energies. In these notes we first discuss the postulates of DSR, and then turn to presenting arguments supporting the hypothesis that DSR can be regarded as a flat space, semiclassical limit of gravity. The notes are based on the talk presented at the conference ``Special Relativity -- Will it Survive the Next 100 Years?''
