What is the subatomic structure of spacetime?

[]

Questions I investigate

  1. What happens to quantum information falling into black holes? Resolving Hawking's famous paradox would be incredibly satisfying.
  2. How does classical spacetime emerge from quantum gravity? c.f.: Qualitatively new emergent phenomena arising in condensed matter systems in the limit of a large number of degrees of freedom.
  3. Where exactly is the quantum-to-classical transition for gravity? And how sensitively does this depend on the precise context?
