Query: From Nuclear to Unnuclear Physics   We provide a brief commentary on recent work by Hammer and Son on the scaling
behavior of nuclear reactions involving the emission of several loosely bound
neutrons. In this work they discover a regime, termed unnuclear physics, in
which these reactions are governed by an approximate conformal symmetry of the
nuclear force. Remarkably, the scaling exponents that govern nuclear reactions
can be related to the energies of ultracold atomic drops confined in harmonic
potentials. We also comment on the importance and the limitations of this
approximate symmetry in the physics of neutron stars.
