## Grave Errors in the LIGO Mathematical Analysis of Gravitational Waves

The original "Observation of Gravitational Waves from a Binary Black Hole Merger", that appeared in the February 2016 issue of *Phys. Rev. Lett.* is fraught with grave mistakes in the mathematical formulation, if it could be called that. In their paper, the LIGO team presents a single equation for the so-called 'chirp mass', and another equation in a caption for the "effective relative velocity given by the post-Newtonian parameter"

$$ (v/c)^3=GM\omega/c^3,$$
