WebOct 8, 2015 · $\begingroup$ The galaxy shrinking is a kind of complicated question in the Milky-way Andromeda example. When 2 galaxies collide, the initial size might expand due to individual stellar orbits being subject to gravity assists, but if 2 stellar mass black holes collide within a galaxy, then, no, the galaxy wouldn't shrink at all because the mass of both … WebOct 16, 2024 · Collimated jets provide astronomers with some of the most powerful evidence that a supermassive black hole lurks in the heart of most galaxies. Some of these black holes appear to be active, gobbling up material from their surroundings and launching jets at ultra-high speeds, while others are quiescent, even dormant.
