vacuum

Mathematically-speaking, a vacuum (twist or twist-in) is a twistor with negative potential. It is the opposite of a bubble. Taken by themselves, vacua are scalar fields of deflatons.

Vacua represent the minimum amount of twistorspace (handicap = $min) per some given opus.
/// +Both bubbles and vacua output the same absolute value.
+Whereas an inflaton will blowup a function at a single point, a deflaton will depress every point in its vector field.

Ludologically, a vacuum will result in juker's ruin, for it is concave downwards against the handicap in twistorspace.
