ABSTRACT
Hippolytus There are innumerable cosmos differing in size. In some there is no sun or moon, in others they are larger than with us, in others more numerous. The intervals between the cosmos are unequal: in some places there are more, in others fewer; some are growing, others again are dying; somewhere worlds are coming to be, elsewhere fading. And they are destroyed when they collide with each other. Some cosmos have no living creatures or plants, and no water at all.
