What it means
Everyone experiences gravity constantly, and yet the constant that sets its strength is pinned down to only a few parts in a hundred thousand, while the electron's magnetic moment is measured to twelve digits. The problem is that gravity is absurdly weak between laboratory-sized objects, and it cannot be screened out, so every nearby mass contaminates the experiment.
The claim comes from NIST.
