Stringent theoretical and experimental bounds on graviton mass

TL;DR

This paper establishes both theoretical and experimental bounds on the graviton's mass, suggesting it is extremely small, around 10^{-32} eV/c^2, consistent with recent gravitational wave observations.

Contribution

It provides a unified theoretical and experimental estimate of the graviton mass, refining previous bounds and confirming their consistency.

Findings

Graviton mass constrained to ~10^{-32} eV/c^2

Theoretical bounds align with gravitational wave data

Supports the massiveness of the graviton within current limits

Abstract

We show from theoretical considerations, that if the graviton is massive, its mass is constrained to be about $10^{-32}~eV/c^2$. This estimate is consistent with those obtained from experiments, including the recent gravitational wave detection in advanced LIGO.
