Example: "In a vacuum, there is an absence of matter, allowing for the propagation of light without obstruction."
Alternatives: "lack of substance" or "void of material".
The energy density in a magnetic field is given in the absence of matter by 1/2B2/μ0; it is measured in units of joules per cubic metre.

Space is an entity in which things are, and not the mere absence of matter.
Therefore, a flat Minkowski spacetime consistent with the complete absence of matter is endowed with an integrable connection and thus determines all (hypothetical) free motions.
Solomon used process models to introduced the concept of non-inertia Ni fields and derived the massless gravitational acceleration formula g = τc2 that is consistent with Hooft's finding that absence of matter no longer guarantees local flatness.
On the contrary, Paul of Venice thinks angels are individuated by means of thisnesses, but not multiplied by them, because of the absence of matter, so that there is only one angel per species.
