Recently, several groups have endeavored to experimentally map the large-scale structure of the Universe with the Sloan Survey being the most ambitious.
At the same time, we've been able to map the cosmic microwave background to 10^-6 degrees. I believe these two maps agree but I'm confused about it. For example, select a portion of the sky, if the CMB indicates a perturbation, will the exact same portion of the sky in the Sloan map indicate some structure such as a super-cluster? And in an area of CMB uniformity, will the same location in the Sloan map be relatively sparse?
Also, the new field of Computational Cosmology has likewise "created" a Universe from theoretical computations alone.
Is the topology of these three maps in agreement? If so, can anyone add more to the interpretation of the results? The info on the net I've been able to read is a bit confusing.
