Big Bang? 5



Because the CMB is so uniform, many thought it came from evenly spread matter soon after a big bang. But such uniformly distributed matter would hardly gravitate in any direction; even after tens of billions of years, galaxies and much larger structures would not evolve. In other words, the big bang did not produce the CMB (j). [See pages 402–404.]

John Travis, “Cosmic Structures Fill Southern Sky,” Science, Vol. 263, 25 March 1994, p. 1684.


“But this uniformity [in the cosmic microwave background radiation, CMB] is difficult to reconcile with the obvious clumping of matter into galaxies, clusters of galaxies and even larger features extending across vast regions of the universe, such as ‘walls’ and ‘bubbles’.” Ivars Peterson, “Seeding the Universe,” Science News, Vol. 137, 24 March 1990, p. 184.


As described below, one of the largest structures in the universe, “The Great Wall,” was discovered in 1989. It consists of tens of thousands of galaxies lined up in a wall-like structure, stretching across half a billion light-years of space. It is so large that none of its edges have been found. An even larger structure, the Sloan Great Wall, was discovered in 2003 and is the largest structure known in the universe.


“The theorists know of no way such a monster [the Great Wall] could have condensed in the time available since the Big Bang, especially considering that the 2.7 K background radiation reveals a universe that was very homogeneous in the beginning.” M. Mitchell Waldrop, “The Large-Scale Structure of the Universe Gets Larger—Maybe,” Science, Vol. 238, 13 November 1987, p. 894.


“The map’s most eye-catching feature is the Sloan Great Wall of galaxies, a clustering of galaxies that stretches 1.37 billion light-years across the sky and is the largest cosmic structure ever found. Astronomers worried that such a humongous structure, 80 percent bigger than the famous Great Wall of galaxies first discerned in a sky survey 2 decades ago, might violate the accepted model of galaxy evolution.” Ron Cowen, “Cosmic Survey,” Science News, Vol. 164, 1 November 2003, p. 276.
