Today the CGPA voted for the redefinition of the kilogramm. Why is nobody talking about this?

>Current definition: The kilogram is the unit of mass; it is equal to the mass of the international prototype of the kilogram.
>2019 definition: The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015×10?34 when expressed in the unit J?s, which is equal to kg?m2?s?1, where the metre and the second are defined in terms of c and ??Cs.

About damn time, if you ask me. Using a prototype kilogram was a disgrace to every theoretical physicist.
