We study the multiplicity and morphologies of large underdense regions of the Universe (the so-called VOIDS) using a differential geometry approach. Our results strongly suggest that prolateness is the dominant morphological feature of voids in our universe. We further compare our observational results with those expected in different cosmological models and find that a flat low-Ω(m) CDM model with low normalization σ(8)=0.83 performs best.
