Can supermassive black holes actually stop a galaxy from growing?

When does the Universe form its stars? · 14:45 · Video: Dr. Becky · Watch at the source

In short: Astrophysicist Dr. Becky Smethurst explores the complex relationship between supermassive black holes and the galaxies they inhabit. The video examines the mechanisms that regulate star formation and the ways in which black holes might influence their cosmic surroundings.

The video focuses on the interplay between supermassive black holes and galactic evolution. Specifically, Dr. Smethurst investigates whether the intense energy output from the accretion disk—the material orbiting a growing black hole—can effectively halt a galaxy's ability to produce new stars.

By focusing on the 'how' of astrophysics, the content highlights the ongoing research into these celestial feedback loops. It addresses a fundamental question of cosmic growth: how do the most massive objects in the universe dictate the lifecycle of the galaxies they call home?
