Two Trillion Galaxies: The Number That Will Break Your Mind

Two Trillion Galaxies: The Number That Will Break Your Mind If you tried to count every galaxy in the universe at a rate of one per second, it would take you sixty-three thousand years—nearly ten times longer than all of recorded human history. In this episode, we explore the staggering reality of our cosmos: an existence home to an estimated two trillion galaxies. But the most chilling realization isn't just the number—it’s that ninety percent of these worlds are completely invisible to our current technology. In this journey, we cover: The Great Recount: How we jumped from an estimate of one hundred billion to two trillion galaxies. Cosmic Giants vs. Dwarfs: From the massive I C one one zero one to the tiny Segue two. The Invisible Skeleton: How dark matter created the Cosmic Web and the massive supercluster we call Laniakea. The Time Machine: How the James Webb Space Telescope is piercing through cosmic dust to see the very first galaxies ever formed. The End of Light: Why the expansion of the universe means that one day, all other galaxies will vanish from our sky forever. We are made of stardust—the universe reflecting upon itself. Join us as we look past the cosmic horizon to discover just how small, and yet how significant, we truly are. #Astronomy #SpaceExploration #Cosmos
