Two water droplets oscillate in sync on opposite shores — perhaps an invisible straw connects them. It's the same with entangled particles: if a quantum wormhole links them, it changes the hydrogen atom's 'radio voice'. Precise measurements don't let wormholes hide.
🎯 The 21 cm radio line is the voice of the universe's most abundant element. Using it, astronomers map invisible hydrogen and hunt for dark matter.
🎬 In 'Interstellar', wormholes are colossal portals between stars; this new work brings those bridges to the subatomic level, inside the hydrogen atom.
