vacuum
In the simplest sense, empty space. However, since a vacuum, either natural or artificial, is never completely empty, the term needs a modifier. Thus scientists speak of a hard vacuum, quantum vacuum, and so forth. See also Casimir effect, vacuum energy drive, and zero point energy.

Vacuum
A vacuum is a space from which the gas has been removed.
