Guys, you won't believe this! Scientists just figured out where half the universe's matter was hiding! Turns out it's chilling in huge, invisible clouds of ionized hydrogen around galaxies—something we couldn't see before. They've developed a way to spot these clouds using light from the cosmic microwave background. Mind blown, right? They think this could change how we understand galaxy evolution and maybe even uncover more cosmic secrets. What do you think? Is our universe more mysterious than we thought? #ScienceMysteries #UniverseUncovered #MindBlown #ScienceMysteries #UniverseUncovered #MindBlown #Science
