Turns out, wormholes—the sci-fi tunnels through space and time—are a total myth! The real Einstein–Rosen “bridge” isn’t a shortcut across the universe, but a mind-bending link between two directions of time. New research says these bridges could help solve the black hole information paradox and even hint that our universe had a ‘before the Big Bang’ era. No time travel, but maybe a universe that bounces back and forth through time! #Science #Wormholes #Physics
