Solved cryptogram
Gravity is the force physicists measure with the poorest precision, despite being familiar.
Physics Facts, sourced to NIST.
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, and the page it comes from was read on 2026-08-27 to confirm it still says this.
This is not the kind of claim that goes out of date, which is why it was set as a puzzle rather than a fact with a shelf life.
