The Meaning of Spacetime: Black holes, Wormholes and Quantum Entanglement / Juan Maldacena

9th "Traektoria" Foundation Workshop for Teachers in Astronomy and Physics. 6 January 2026. The lecture starts by describing the geometrical notions central to Einstein's theory of gravity. Then we discuss current ideas for how spacetime geometry could emerge in a quantum theory of gravity. We will see that quantum entanglement plays a crucial role. Juan M. Maldacena – Argentine theoretical physicist and the Carl P. Feinberg Professor in the School of Natural Sciences at the Institute for Advanced Study, Princeton.
