Is Physics Asking for a New Kinematics?

TL;DR

The paper explores replacing special relativity with de Sitter relativity to address foundational issues in physics, proposing a universal framework valid across all energy scales.

Contribution

It introduces de Sitter relativity as a potential solution to the consistency problems of current physics, extending the kinematic framework beyond special relativity.

Findings

De Sitter relativity may resolve issues at the Planck scale.

It offers a universal kinematic model applicable at all energy scales.

Potential implications for the foundations of physics.

Abstract

It is discussed whether some of the consistency problems of present-day physics could be solved by replacing special relativity, whose underlying kinematics is ruled by the Poincare' group, by de Sitter relativity, with underlying kinematics ruled by the de Sitter group. In contrast to ordinary special relativity, which seems to fail at the Planck scale, this new relativity is "universal" in the sense that it holds at all energy scales.
