I talk in depth about the size of the Andromeda Galaxy.
We are taught to think of space as a giant empty room with a few scattered lights. But the more humans have stared at the sky, the more it has behaved like a trick mirror, quietly breaking our sense of what big even means. For a long time, even expert scientists were sure our own galaxy was almost everything there was. Then the sky proved them wrong again and again. In this video, we'll slow down together and look more closely at one nearby galaxy and learn what big really is out there.
