Some try to derive gravity from quantum field theories that don’t have gravity in them

In theoretical physics, the AdS/CFT correspondence is called Maldacena duality or gauge/gravity duality.

  • Juan Maldacena applied the holographic principle to black holes and anti-de Sitter space. Because there’s no gravity there, you can define quantum field theory on it and have no conceptual issues quantising it.
  • Mark Van Raamsdonk, Brian Swingle and others pointed out that if you fiddle with the amount of entanglement between different parts of the quantum field theory on the boundary without gravity, the geometry of the anti-de Sitter space inside changes in response to that.

Strange things happen when you try to combine Einstein’s description of curved space-time with a universe made up of quantum wavefunctions. This podcast shows how space and time are emergent properties of quantum reality but not fundamental parts of it.
