How Many Galaxies Actually Exist in the Universe
Notes de l’épisode
We can't even count the stars in our own sky — so how do we dare to count the galaxies? The answer is far more unsettling than you might expect. In this episode, we break down how astronomers estimate the number of galaxies in the observable universe, why the figure keeps changing, and what it means that most of them are too faint and too far away to ever be seen. The universe isn't just vast — it's incomprehensibly crowded. Press play and try to wrap your mind around infinity.
