The answer is found in the way the hidden scale symmetry involving a dilatonemerges in strong nuclear correlations in nuclear matter. It is suggested thatthe same mechanism is at the origin at higher densities of the sound speedconverging in the core of massive compact stars to what could be called``pseudo-conformal sound speed" $v_s^2/c^2\approx 1/3$. A precision measurementof the superallowed Gamow-Teller transitions in the doubly magic nucleus$^{100}$Sn is suggested to confirm or falsify this prediction. It could alsolead to the possible determination of genuine ``fundamental renormalization" of$g_A$ in nuclear medium.

What "quenches" ${g_A}$ in nuclei ?
