this is ye olde aetherist ideale,
in which Pascal's discovery of "the plenum,"
was thought to be that of a perfect vacuum,
which of course does not exist, any where.

that is to say,
Pascal did not have the comcept of "partial pressure"
of mercury & glass in the evacuated glass tubing,
nor of gasses dissolved in the mercury.

there simply is no "empty space," although
exactly "where teh atoms are" is subject
to the uncertainty principle (viz Heisenberg,
between any two algebraically covariant properties).
