We should therefore consider that there are several vortexes similar to the one we have just briefly described; that the centers of these vortexes are the stars, which are so many suns; that the vortexes surround each other, and that they are arranged in such a way that they hinder each other as little as possible in their movements; but that things could not have happened this way unless the weakest vortexes had been carried away and, as it were, absorbed by the strongest.
