What James Webb Saw at the Universe's Edge — It's Not Good

#JamesWebb #DeepSpace #Universe

James Webb stared at a patch of sky smaller than a grain of sand held at arm's length. In that tiny sliver of darkness, it found thousands of galaxies. Some of them are so far away their light has been traveling since before our Sun existed. And several of them should be impossible. We'll go to the edge of everything we can see. We'll meet galaxies that break the rules, black holes that grew too fast, and a force pushing the universe apart that no one fully understands. If you enjoy the journey, like and subscribe — it keeps these going. Prepare yourselves. We begin.
