The VECRO hypothesis

Understand

We consider three fundamental issues in quantum gravity: (a) the black hole information paradox (b) the unboundedness of entropy that can be stored inside a black hole horizon (c) the relation between the black hole horizon and the cosmological horizon.

• With help from the small corrections theorem, we convert each of these issues into a sharp conflict.
• We then argue that all three conflicts can be resolved by the following hypothesis: {\it the vacuum wavefunctional of quantum gravity contains a `vecro' component made of virtual fluctuations of configurations of the same type that arise in the fuzzball structure of black hole microstates}.
• Further, if we assume that causality holds to leading order in gently curved spacetime, then we {\it must} have such a vecro component in order to resolve the above conflicts.
