The quasar's flickering indicates how gas is being fed into the black hole, which helps reveal how supermassive black holes grow.
The Frontline Impact
How this affects you
This discovery of a mature-appearing quasar from 12.9 billion years ago provides new evidence for the theory that supermassive black holes formed and developed exceptionally early in the universe's history. It challenges previous assumptions about the growth phases of black holes, suggesting they mature much faster than previously thought.
