Summary

Story summary

The LIGO–Virgo–KAGRA collaboration's analysis of black hole mergers provides strong support for general relativity, with no evidence of alternative models.
The first paper confirms general relativity's consistency with observations, while the second constrains alternative models via post-Newtonian parameters.
The analysis sets an upper limit on graviton mass at less than 2 × 10^-23 eV/c², highlighting the precision of current gravitational wave data.
