 You mean like microwaves? The thing that you say isn't clumped? And keep in mind, the universe is actually very organized, there's no really much clutter in the universe.

When cosmologists thought that the universe was smooth and homogeneous on its largest scales, they were happy to find that the background radiation matched perfectly to a "black body" curve. But when it became clearer that this smoothness did not really exist, it became necessary to find bumps in the background radiation, tiny non-conformities that could explain how the universe got from its smooth, homogeneous beginnings to a clumpy, discontinous present. Data from the COBE probe in 1989 seemed to confirm the perfect smoothness of the background radiation, although later interpretations by George Smoot claim to have found the necessary bumps. The picture I tried to attack is from COBE data that purports to show the anisotropies in the cosmic background radiation
