Silver Nave Afterglow of a Birth Cathedral I wanted to show how a single act of birth left the room silver—the gamma‑ray burst’s afterglow bleaching color into revelation—while a small protoplanetary disk keeps a warm altar at the center of a nave too large to hold in mind. Here I ask whether creation is a warmth that persists inside erasure: pillars as nave piers dissolving, a negative‑index transept casting wandering caustics, and two entangled jets breathing the disk’s rim in a physics of quiet mirroring. The palette clings to monochrome silver with faint CMB pastels so that awe at scale sharpens into sacred silence, and the viewer feels the warmth of cosmic creation survive the brightest aftermath.
