The Impossibility of a Vacuum

There is no ratio of a vacuum to a plenum, but these things happen so far as the media differ through which they are moved. Things which have a greater momentum either of weight or levity will be more swiftly carried through an equal space than those with similar figures. The cube however, has as much magnitude as the vacuum contains and permeates it throughout. In every body which may be transferred unless it is compressed that it should be transferred either always downward if itslation is downward as earth, or upward if it is fire.
