8. Black Hole Mergers: Catalysts for Galaxy Evolution
When black holes collide and merge, they unleash titanic bursts of energy that can reshape entire galaxies. These dramatic events trigger growth spurts, creating larger and more powerful black holes at galactic centers. The resulting gravitational waves and energetic feedback can spark the formation of new structures, such as stellar streams and galactic cores. As described by LIGO, black hole mergers are essential milestones in the ongoing evolution and transformation of galaxies throughout the cosmos.
