Is quantum entanglement real, or is Einstein’s skepticism about quantum physics justified? Turns out that Einstein may be right. “The universe might be like a restaurant with 10 menu items, Friedman said. ‘You think you can order any of the 10, but then they tell you, ‘We’re out of chicken,’ and it turns out only five of the things are really on the menu. You still have the freedom to choose from the remaining five, but you were overcounting your degrees of freedom.'”
