| Abstract: | The author proposes the possibility to observe the HI column density oscillation in small scales (∼ AU-scale). If such variance
of the column density were to be observed, he would suggest that the observational results show the existence of some type
of waves in two-phase gas mixture. Such wave is known to be a void wave in the context of multi-phase fluid dynamics. If the
variation of HI column density is representation of the void wave, we can also expect the HII density variations have anti-correlation
to the HI density fluctuations, in the context of classical two phase model of interstellar medium.
