       | Which mass is this referring to? Rest mass, inertial, or a
       | different one?

       | Could this be related to the Heisenberg's uncertainty principle?
       | Or be an artifact caused by the measurement?

         | Neither. It's simply a counterintuitive consequence of weak

         | the article does, sounds _more_ counterintuitive than it
         | actually is.

       | Oy, veh; that abstract is a mess, even given that IANAphysicist.
       | For instance, I'm thinking that "the counterintuitive result has
       | been obtained that a neutron is" can be replaced by "a neutron
       | can be".

       | Language matters; if your writing is unnecessarily dense and
       | confusing, your ideas are probably the same, you just don't know
       | it yet.

         | The writing was so obtuse. Before sharing I had to edit the
         | quote and make it more direct.
