Most stellar-mass black holes may be completely alone—and virtually invisible. In this episode, we explore new simulations suggesting that over 90% of the Milky Way's black holes have no companion star, making them extremely difficult to detect.

Future missions like the Roman Space Telescope could finally uncover this hidden population, transforming our understanding of black holes and the evolution of our galaxy.
