Draft additions October 2011

nature abhors a vacuum and variants [compare post-classical Latin natura abhorret vacuum (1513 or earlier)] : a vacuum or unfilled space is unnatural; something will inevitably move in to fill an empty space or niche. Used both literally with reference to physical laws concerning vacuums, and (more often) in extended, allusive, or similative contexts. Cf. horror vacui n.Allusive and similative use often extends to use of a noun other than nature (and occasionally a noun other than vacuum; see quot. 1823, for example).
