       | Edit:
       | 
       | They are observing
       | https://en.wikipedia.org/wiki/Feshbach_resonance in NaLi gas that
       | has been cooled down to 1.8uK.
       | 
       | In a nutshell when the applied magnetic field is almost precisely
       | 334.92 Gauss the NaLi molecules couple together a lot more than
       | normal because the magnetic field affects the energy levels of
       | the molecules (the electrons in the molecules). When the energy
       | levels match then certain coupled states are far more likely to
       | happen.
       | 
       | Previously this has been observed between atoms but not between
       | molecules (NaLi)

         | particles, molecules, etc but these frequencies are just ones
         | we can't pickup, can't induce or manipulate yet. Or is that
         | totally obvious or just dumb? Yes, I know about gravitons
         | somewhat, and admittedly I'm not that versed in physics, but
         | could that be how the particles manifest in wave form, ie, at
         | large scale?
