Quantum entanglement
You'll understand how quantum particles exist in multiple states simultaneously and why measuring them forces a single outcome.
You'll learn how two particles can become correlated so that measuring one instantly affects the other, defying classical intuition.
You'll see why Einstein questioned quantum mechanics and discover how experiments prove particles can influence each other faster than light allows.
You'll grasp why Bell's theorem rules out hidden variables and confirms that quantum entanglement is genuinely nonlocal, not just hidden coordination.
