Plural vacuums vacuua
  1. A region of space in which there is no matter.

Note

In the natural world, air will flow into regions of vacuum, giving rise to the saying “Nature abhors a vacuum.”

Note

The saying is extended informally: in politics, a lack of leadership may be referred to as a vacuum, which will presumably be filled by others rushing in.
