Abscent of anything quantative or qualitative.
Science is discovering that something like you are describing probably doesn't exist. The word "Nothing" (note the capitalization to differentiate it from the common use of the word) is coming to mean something different, quantum fluctuations, a world where it may be possible to actually measure how smooth spacetime is, where particles pop into and out of existence. This all happens in empty space that was once thought to contain "nothing".
