...galaxies at least 200 million light-years wide, 500 million long and perhaps 15 million thick. It looks like a single structure, but the scientists say it may instead be made up of the walls of adjacent bubbles. Says Geller: "Because it runs off the edge of our survey, we don't know how big it really...
...study is not the first to see dark voids and large conglomerations of galaxies, but it is by far the most comprehensive. The reason no one had done such a search earlier, says Huchra, is that galaxy mapping is extremely time consuming. Their survey of 4,000 galaxies took about 1,000 hours of telescope time...
...meantime, the CfA study will go on, and other mapping efforts are in the works. "Big as it is," Geller explains, "our survey area compared with the visible universe is like Rhode Island compared with the surface of the earth." The bubbles and walls could be isolated phenomena. But, notes Geller: "Every survey ever done has contained structures as big as the survey could contain." If that trend continues, then there are larger objects yet to be found, which will give theorists even worse headaches. "These surveys test in the most acute way our conceptions of how structure developed...
