In the nearby universe, gravity has organized galaxies into great walls, voids, and filaments, and many cosmologists believe these structures are latecomers to the cosmos. But new observations made by a Caltech team with the Keck 10-meter telescope in Hawaii suggest that wall-like structures may have already been common in the universe billions of years ago. If the findings hold up, theorists may have to revise ideas about the density and makeup of the universe.
