Juan Maldacena wrote the most cited paper in theoretical physics, birthing AdS/CFT and realizing holography — and today, the problem keeping him up at night is wormholes. He suspects space-time isn't fundamental at all, that geometry itself might be what entanglement looks like from the inside. The singularity isn't a place, it's a name for everything we don't yet understand. I hope you enjoy it.
