The hypothetical practice of designing and constructing systems that operate across the multiverse—bridges between universes, communication networks across realities, structures that exist in multiple universes simultaneously. Multiverse engineering would require materials that exist in all universes, construction techniques that work across different physical laws, and quality control that ensures a bridge stands in universe A even if it fails in universe B. It's engineering on a scale that dwarfs anything imaginable—inter-universal infrastructure for a civilization that spans realities. Multiverse engineering is pure science fiction today, but so was spaceflight once.
Example: "She dreamed of multiverse engineering, designing a bridge that connected all the universes where she'd made different choices. In one universe, she was a doctor; in another, an artist; in another, a mother. The bridge would let all her selves visit, compare notes, share lives. The engineering was impossible; the dream was not."
