The Information Paradox
Testing Complementarity: The Observer's Dilemma
2 / 5
Black Hole Complementarity proposes that there is no contradiction because the two observers cannot communicate. Alice falls in and keeps the information. Bob sees it radiate out. But Alice can never return to tell Bob she still has it. Since they can never compare notes, no single observer sees information cloned. Try the simulation to see why this preserves quantum mechanics.
