It does look fractal at the distances we can see. Perhaps it become homogenous at a point further than we can see now. I don’t know if it is fractal downward toward the small end, though.

For decades cosmologists have wondered if the large-scale structure of the universe is a fractal: if it looks the same no matter the scale. And the answer is: no, not really. But in some ways, yes. Look, it’s complicated.

Our universe is unimaginably vast and contains somewhere around two trillion galaxies. These galaxies aren’t scattered around randomly, but are assembled into a series of ever-larger structures. There are the groups, containing at most a dozen galaxies are so. Then there are the clusters, which are home to a thousand galaxies and more. Above them are the superclusters, which twist and wind for millions of light-years.
