Which came first: black holes or galaxies?

The insights upend theories of how black holes shape the cosmos, challenging classical understanding that they formed after the first stars and galaxies emerged. But the analysis by Silk's team suggests that black holes and galaxies coexisted and influenced each other's fate during the first 100 million years. Black holes are regions in space where gravity is so strong that nothing can escape their pull, not even light. This process, he said, is likely why Webb's detectors have spotted more of these black holes and bright galaxies than scientists anticipated. During the first phase, high-speed outflows from black holes accelerated star formation, and then, in a second phase, the outflows slowed down.
