Imagine a journey through the universe to another place, the destination is a home, a new earth.  The journey would be millenia long, and the ship would be the mother of the universe.  She could be Isis, and an Osiris (yet) to be important.  Her womb would carry the whole of humanity, to birth them in a new world.  The electronics sustain life in the womb, a delicate protection for the delicate cargo.

Steel, wire, electronics.
