Now your home is filled with these, you better submit and obey government or else.

This gives a hint as to why the different RGB thing comes about. All is energy held together by resonance, from a single proton to the cumulative resonance of objects, they all have a resonant frequency that makes the opera singer's voice a weapon. These frequencies do not need to be of high energy because if done correctly they can pump the lower energy in to build up to the breaking point. Also the frequencies don't need to be super high because the cumulative resonant frequency or "collective excitation" tends to be in the sound range called a phonon, and it's magnetic spin equivalent, the collective "spin wave" called a magnon .
