Relict radiation has spatial fluctuations: hot and cool spots. Of rather modest amplitude, but yet detectable. Have these patterns undergone any change? Galaxies are supposed to form a few hundred million years after big bang. If you watched a given hot spot of relict radiation, would it eventually be seen to evolve into a galaxy cluster, and cold spots into voids, or vice versa? And how long would it take in order to watch an object visible as a relict radiation pattern as of now to evolve into a young galaxy?
