 Hennon believed that nature abhors a vacuum and therefore no natural void was possible, though God could create one.A void, however, is not defined by a positive distance between surfaces in which there is nothing, but rather as the capacity ("potentialitas") for a body to be interposed between the two surfaces equal to that which is there when it is full.Hennon affirms that ice is denser than liquid water, and that a sealed vase of water will break upon freezing because nature abhors a vacuum.
