Cold Spot in Cosmic Background Radiation

[Hugh Parker]

At one time, I read that the universe was, on a very large scale, essentially the same in all directions. Recently I have learned about the Cold Spot in the fairly uniform Cosmic Background Radiation map. Scientists have attributed the artifact to a very very large void in the ordinary matter of the universe. Does the existence of such a large large feature mean that we can no longer assume that the universe is essentially the same in all directions?
