—transparent, silent, omnipresent. It is the unseen glass upon which the universe paints itself, the screen through which all becomes visible. Like the old cathode ray tubes that once lit our living rooms in static glow, spacetime is the substrate, the architecture, and the canvas. The cosmic microwave background? Just the afterglow on the glass. All things arise and move within this field—not just energy and matter, but memory, thought, gravity, and the echo of creation itself. We are not in space; we are of spacetime—etched into the glass of becoming.
