We Found Galaxies Too Old for the Universe
Season 11
Episode 27
The James Webb Space Telescope found galaxies that are too ancient-looking for our young universe. You may have heard that, but it keeps finding them, and our recent efforts to solve this conundrum point in wildly different directions. Have we found galaxies older than the universe, or did we just learn something incredible about how galaxies form?
