The cosmic chicken-or-egg dilemma: Did galaxies or black holes arrive first?
In short: Astrophysicists are grappling with a fundamental mystery of the early universe. This video explores the complex relationship between supermassive black holes and their host galaxies, using new data from the James Webb Space Telescope to untangle how they shaped one another.
Dr. Becky Smethurst investigates whether supermassive black holes formed first or if they grew as a byproduct of galactic evolution. Her research specifically examines the feedback loop between these giants and their surroundings, focusing on how energy output from an orbiting disk of material can actively suppress a galaxy's ability to form new stars.
It matters because understanding this interaction reveals the primary drivers of galactic structure and the lifecycle of matter in our universe.
