Final answer:
The question about Sara Bisel and Estelle Lazer's work seems misdirected, but similar work in the field of large-scale cosmic structures by Margaret Geller and John Huchra is notable. Their astronomical surveys have revealed the 'cosmic web' of galaxy clusters and vast voids, advancing our understanding of the universe's structure.
Step-by-step explanation:
The question seems to pertain to physical anthropologist Sara Bisel and archaeologist Estelle Lazer's work, but there might be a confusion with the names provided. However, to share knowledge in a similar spectrum, we can briefly talk about the work of Margaret Geller and John Huchra. Margaret Geller is an astronomer who, along with John Huchra, conducted a significant survey of the sky, creating maps of the universe showing the distribution of galaxies. Their work highlighted the existence of large-scale structures in the universe, with galaxies being distributed in what is known colloquially as the 'cosmic web', consisting of galaxy clusters, superclusters, and vast voids in between. These investigations have been pivotal in understanding the large-scale structure of the universe and have provided invaluable information for the field of cosmology and astrophysics.
