    Physicists Simulate Time Travel Using Quantum Entanglement

    The quantum world operates by different rules than the classical one we buzz around in, allowing the fantastical to the bizarrely normal. Now, a team of physicists has used quantum entanglement to simulate a closed timelike curve—in layman’s terms, time travel. Before we proceed, I’ll stress that this was simulated; no quantum particles went back…
