Abstract
We examine spectrum of the physical volume operator within the non-standard loop quantum cosmology. The spectrum is discrete with equally distant levels defining a quantum of the volume. The discreteness may imply a foamy structure of spacetime at semi-classical level which may be detected in astro-cosmo observations.
