Black light, not the internet version at http://en.wikipedia.org/wiki/Black_light, could be defined as transverse monochromatic waves that are completely out of phase. Zero sound similar to the internet version at http://en.wikipedia.org/wiki/Zero_sound could be defined as longitudinal waves confined within a Fermi liquid, for example He, an isotope of helium having nuclei of half integral spins. In contrast, Bose liquids are formed from He, isotope of helium having nuclei of integral spins.

It can now be stated without proof that both phenomena form fractal quanta of the true vacuum. That is for each unit quantum of the true vacuum, it is composed of two quanta of black light and one quantum of zero sound.
