According to recent observations, there seem to be a lot of spherical voids in the cosmos. These vast nothingnesses are closed in by nearly spherical shells of galaxies. In other words, the cosmos consists of foam; homogeneous in the large, but bubbly in the small -- if spherical shells of galaxies can be considered "small." The only way, say the theorists, that such a foamy structure can arise is for the universe to be closed, not flat as counts of galaxies seem to indicate. Thus, the foamy cos-mos infers that we do not detect a lot of the mass existing in the universe.

Comment. In the Better, Bigger Big Bang there seems to be plenty of room for a foamy section or two!
