Because Direct Materials Inventory reports the standard cost of the actual materials on hand, we reduce the account balance by $870 (290 yards used $3 standard cost per yard). After removing 290 yards of materials, the balance in the Direct Materials Inventory account is $2,130 (710 yards x $3 standard cost per yard).
void (plural voids) 1  An empty space; a vacuum. ( 2 astronomy) An extended region of space containing no galaxies. ( 3 materials science) A collection of adjacent vacancies inside a crystal lattice. ( 4 fluid mechanics) A pocket of vapour inside a fluid flow, created by cavitation.
Space is a vacuum because the word vacuum means empty space. If the universe had no emptiness (almost emptiness, as the posters before me have stated), we would not use the word space for it. So space, by its very definition in English language, is emptiness.
