The answer is yes.
A first example is the ultra-weak X-ray sources of Riccardo Giacconi’s which are equi-distributed across the sky.
Another is the so-called “dark galaxies” which are actually ultra-old.
A third is the invisible ordinary dark matter in galactic clusters and super clusters.
A fourth is the empirical fractal structure of the cosmos detected by my friend Benoit Mandelbrot.
