In Search of Time’s Origin

Physicists are not certain that time exists:

Maldacena’s model provides more support than ever for the claim that, when it comes to cosmic ingredients, entanglement is more fundamental than space and time. Time, it turns out, is not present at the most basic layer of reality; it springs from fundamental seeds. But while emerging physics suggests time is an illusion, the forces that conjure it remain at large. “My intuition is that it will take more than just a re-working of quantum physics, it will require a breakthrough that will come totally out of left field,” Seiberg says. “Only time will tell what that revolution will be.”
