In 1977, [[Stephen Weinberg]] observed that "the theory of the formation of galaxies is one of the great outstanding problems of astrophysics, a problem that today seems far from solution". Although the past two decades have seen considerable progress, many questions remain. <ref>http://www.nature.com/nature/journal/v400/n6741/full/400220a0.html</ref>
Creationists also cite the following:
“In its simplest form, the [[Big Bang Theory|Big Bang]] scenario doesn’t look like a good way to make galaxies. It allows too little time for the force of gravity by itself to gather ordinary matter—neutrons, protons and electrons—into the patterns of galaxies seen today. Yet the theory survives for want of a better idea.” Ivars Peterson, Science News, "Seeding the universe: how did matter assemble itself into the giant filaments, clusters, bubbles and walls of galaxies that now fill the universe?" March 24, 1990, p. 184. <ref>http://www.creationscience.com/onlinebook/ReferencesandNotes61.html#wp1212721</ref><ref>http://findarticles.com/p/articles/mi_m1200/is_n12_v137/ai_8878747</ref>
“It [the Great Wall, composed of tens of thousands of galaxies] is far too large and too massive to have formed by the mutual gravitational attraction of its member galaxies.” M. Mitchell Waldrop, “Astronomers Go Up Against the Great Wall,” Science, Vol. 246, 17 November 1989, p. 885. [See also Margaret J. Geller and John P.
