Juan Maldacena: What Is A Wormhole? (#338)

Aug 15, 2023
Juan Maldacena, famous physicist known for his work on black holes and AdS CFT, joins Brian Keating to discuss topics such as human traversable wormholes, the multiverse, black holes, wormholes in movies like Interstellar, an economic analog to the Higgs Mechanism, and the fascination with time travel. They also explore the construction of a humanly traversable wormhole, the connection between non-Gaussianities and primordial gravitational waves, and the possibility of finding non-gassy entities in large-scale structure.

Quick takeaways

  • Black holes the size of the Earth could be traversable without being killed by tidal forces near the singularity.
  • Recent developments propose the existence of traversable wormholes by exploiting the quantum entanglement of black holes.

Black Holes and Wormholes

Black holes have long been considered deadly due to the immense tidal forces near the singularity. However, in the case of a black hole the size of the Earth, it would be possible to fall into the event horizon without being killed by tidal forces. Similarly, wormholes, which connect two points in spacetime, could potentially be traversable if they have a large enough opening. These concepts have sparked interest in exploring black hole interiors and understanding the nature of quantum gravity and inflationary cosmology.
