How does the dirty snowball theory explain some of the observed characteristics of comets and how may this description not be correct?

Comet nuclei have been described as dirty snowballs or icy mudballs, but that seems to be incorrect; their shapes, low densities, and lack of material strength suggest that comets are not solid objects. The evidence leads astronomers to conclude that most comet nuclei must be fluffy mixtures of ices and dust with significant amounts of empty space.
