High-energy jets emerge from two sides of a black hole (illustrated). The black hole resides in a galaxy that is part of a filament of the cosmic web (silvery wisps). E. Wernquist, M. Oei, D. Nelson/IllustrisTNG Collaboration The definition of a black hole allows for these objects to have a wide range of sizes. Basically, every mass requires some amount of velocity to escape its surface. Our planet has an escape velocity of 11.2 km/s. The asteroid Bennu had a minimum escape velocity of 17 cm/s, but those escape velocities are due to the sizes of each object. As you compress a world smaller...
