Super-Clusters of Galaxies Give Clues to the Big Bang - Universe Today
Astronomers with the European Southern Observatory have embarked on a decade-long study of some of the largest structures, galaxy clusters, to try and understand the nature of the earliest Universe. According to the widely accepted "inflationary theory" of the cosmos, tiny fluctuations in the initial state of the Universe were magnified by the Big Bang. Microscopic differences at the beginning have become super-clusters of galaxies. A previous survey used X-ray observatories to identify 447 of the brightest clusters of galaxies, which will now be studied further to map out their shape.
