Why do supermassive black holes sit at the centers of most large galaxies?
Quick Answer
Galactic centers are where matter tends to gather over time, and repeated mergers and gas inflows help grow a central black hole. These black holes can reach millions or billions of solar masses.
The Full Story
Most large galaxies appear to host a supermassive black hole in their central region. Over cosmic time, gas can fall toward the center, stars can be captured, and smaller black holes can merge there. This steady feeding, combined with galaxy mergers, helps the central black hole grow enormously. Sagittarius A* at the center of the Milky Way has a mass of about 4 million Suns.
