/space8dWormholes may not exist—we've found they reveal something deeper about time and the universeThis article explores a new interpretation of Einstein-Rosen bridges, suggesting they reveal deeper insights about time and the universe rather than serving as wormholes. The original concept, introduced by Einstein and Rosen in 1935, was a mathematical link between two symmetrical copies of spacetime, not intended for travel but to maintain consistency between gravity and quantum physics. Recent research shows that these bridges act as a mirror in spacetime, connecting two microscopic arrows of time. This reinterpretation offers a path to reconciling quantum mechanics and general relativity, potentially resolving the black hole information paradox and suggesting that our universe may have had a history before the Big Bang.
