The Space Show Presents Hotel Mars with Dr. Pieter van Dokkum of Yale regarding "runaway blackholes."
Published: March 17, 2026
Duration: 19:00
John Batchelor and I welcomed Dr. Peter van Dokkum of Yale to define and discuss runaway black holes which are supermassive objects expelled from galaxies after massive collisions. These objects move at 1,000 kilometers per second, escaping their host galaxies to roam through intergalactic space.
Astronomers first detected a runaway black hole via a shock front and a wake of 100 million newborn stars. This stellar trail traces the black hole’s path as it travels through intergalactic gas per the description used by John Batchelor for this Hotel Mars program.
