How Are Galaxies Born?

How Are Galaxies Born? There was only darkness at first. It was calm, cold, and quiet. Not a star. Not a light. Not a galaxy. There is only a thick soup of unseen particles floating in a void that is getting bigger. But in the middle of all that chaos, tiny ripples appeared. These were quantum shakes, which were only a proton wide but would grow into galaxies. After billions of years, we can see the result: beautiful spirals, huge ellipticals, and ghostly dwarfs spread out in a web-like pattern in space. But how did these huge buildings get built? What chain of events turned the shapeless gas we see through binoculars into the huge towns of stars we see now? This is the confusing, violent, and surprising story of how galaxies came to be. Let's start with the beginning: a quantum hiccup that changed the course of history.
