Description
Exactly half of a century ago Wheeler and de Witt wrote the iconic first equation of quantum gravity. Puzzlingly, the equation does not feature any time variable. Where is time gone? How can we describe the evolution of physical systems in absence of a preferred time variable? How can time emerge in the passage from the quantum to the classical world? I will review the problem, the strategies adopted to overcome it and some insights from ongoing research in quantum gravity.
