Astronomers just found a massive, 23-million-light-year gas filament connecting galaxy clusters—finally solving the mystery of the universe’s 'missing matter.' Turns out, all that ordinary stuff (not dark matter!) we couldn’t find was hiding in these hot, cosmic superhighways all along. The best part? This discovery matches what our universe models predicted for decades. Space nerds, our cosmic web dreams are real! #SpaceNews #CosmicWeb #Astronomy #Science
