Abstract
This seminar asks how massive black holes grew so quickly in the early Universe. It places the Milky Way's central black hole in the broader population of galactic nuclei, then examines the first billion years of growth. Exceptionally rapid early development challenges current explanations and shapes later cosmic evolution.
