“One finds that time just disappears from the Wheeler-DeWitt equation,” says Carlo Rovelli, a physicist at the University of the Mediterranean in Marseille, France. “It is an issue that many theorists have puzzled about. It may be that the best way to think about quantum reality is to give up the notion of time – that the fundamental description of the universe must be timeless.”
– Carlo Rovelli. Remember this next time you turn up late for an appointment.
