Democritus holds the same view as Leucippus about the elements, full and void.
. . he spoke as if the things that are were in constant motion in the void; and
there are innumerable worlds, which differ in size. In some worlds there is no
sun and moon, in others they are larger than in our world, and in others more
numerous. The intervals between the worlds are unequal; in some parts there
are more worlds, in others fewer; some are increasing, some at their height,
some decreasing; in some parts they are arising, in others failing. They are
destroyed by collision one with another. There are some worlds devoid of
living creatures or plants or any moisture.
