No. Black holes are predicted to behave somewhat like dark matter. Scientists thought previously that the dark matter in the universe might be lots of invisible black holes. The recent observations of how dark matter organizes itself into structures, such as galaxies and clusters, tend to suggest the idea is wrong.
