The unspoken suggestion oftentimes is that the vacuum is nothing. But it is not nothing. It is a continuum of at least space/time dimensionality.
Space/time does not pre-exist. It is created as the universe expands. The universe doesn't expand "into" anything.
Ditto for the singularity of the big bang. It is not nothing either. It is zero dimensions, a mathematical point, but not nothing.
God created all that there is ex nihilo - no dimensions at all. No thing. No mathematical point.
“The unspoken suggestion oftentimes is that the vacuum is nothing. But it is not nothing. It is a continuum...”
Spirited: The great masters such as De Vinci understood this principle. In practice it means that in order to accurately render the physical “thing” it is necessary to study and render just as accurately the “negative space” (continuum) around and giving shape to the “thing.”
With respect to Christian tradition, totality consists of the seen (physical things) and unseen (spiritual; negative space). Additionally, there are 3 heavens. The first or lower heaven consists of the space around and up to the moon. This heaven is the realm of fallen angels and demons. The second heaven is what we call deep space. The 3rd Heaven or Paradise is outside of the first two and is where the immortal souls of God’s children await the day of resurrection when all things are renewed.
I believe that our earth and the first two heavens are the “things” and the continuum or “negative space” around and giving shape to the “thing” is not the 3rd Heaven itself but an inter-dimensional space or corridor between the first two heavens and the third. C.S. Lewis explored this theme in the Magician’s Nephew, the second of his highly acclaimed Chronicles of Narnia. The Magician represents the mystical speculations of New Physics ‘scientists’ btw.
If Lewis is correct, then the inter-dimensional corridor is the Void, the object of mystical speculation, meditation, astral travel, and empowerment (the Western Magic Way or magic science) from the time of Hermes Trismegistus.
As all things are created and sustained by the Triune God, the worship of created stuff (i.e., the Void) constitutes apostasy and idolatry.
