Plat - Correct.<br /><br />However, we live in the local section which is the best studied and is not expanding.<br /><br />It is actually awesomely complex. The overall pattern is like an expanding gauze with threads and filaments.<br /><br />Walls have also been discovered.<br /><br />And the local river involves thousands of galaxies and hundreds of millions of light years, a significant portion of the observable universe.<br /><br />Concerning this local structure, note this quote:<br /><br />"The Milky Way, Andromeda, and some 20 other galaxies are bound gravitationally into a cluster, all of these being only a small neighborhood in a vast supercluster. The universe contains countless superclusters, and the picture does not end there.<br /><br />The clusters are not evenly distributed in space. On a grand scale, they look like thin sheets and filaments around vast bubblelike voids. Some features are so long and wide that they resemble great walls. This may surprise many who think that our universe created itself in a chance cosmic explosion. "The more clearly we can see the universe in all its glorious detail," concludes a senior writer for Scientific American, "the more difficult it will be for us to explain with a simple theory how it came to be that way."- "Is there a Creator who Cares about You?", chapter 2 entitled "How Did Our Universe Get Here?--The Controversy," 1998, pp. 10,11<br /><br />Additional detail is in this article excerpt:<br /><br />"Still another problem for the big bang has come from steadily mounting evidence of 'bubbles' in the universe that are 100 million light-years in size, with galaxies on the outside and voids inside. Margaret Geller, John Huchra, and others at the Harvard-Smithsonian Center for Astrophysics have found what they call a great wall of galaxies some 500 million light-years in length across the northern sky. Another group of astronomers, who became known as the Seven Samurai, have found evidence of a different cosmic conglomeration, w
