It has been proposed by MIT physicists that if most of the dark matter in the universe is incorporated into microscopic primordial black holes, these should race through our solar system at least once per decade at veloci

The final parsec problem is an astronomical puzzle involving the dynamical evolution of supermassive black holes (SMBHs) at the centres of most galaxies.

In cosmology, the prevailing model that describes the universe is the Lambda Cold Dark Matter (ΛCDM) model.

Relic galaxies, a rare subset of galaxies, stand as cosmic anomalies, seemingly "frozen" in time.

Abell 3827 contains a few hundred galaxies and is located about 1.4 billion light-years away from us.
