Programme
Monday
Insights from quantum gravity
13/07/2026
Theories of quantum gravity may contain all the necessary ingredients to provide a complete picture of black hole interiors. However, all known quantum frameworks face conceptual and mathematical challenges making such a complete picture difficult to achieve. We will discuss what we have learned about black hole interiors despite these challenges.
Tuesday
Effective field equations
14/07/2026
Effective field theory or phenomenological arguments can be invoked in order to construct effective or phenomenological field equations that can provide new insights on the dynamics of black hole interiors, without necessarily resorting to a specific quantum gravity theory. We will discuss the applications of such effective formalisms as intermediate effective descriptions.
Wednesday
Exact and numerical solutions
15/07/2026
We will discuss spacetimes that arise either as exact or numerical solutions of (effective) field equations beyond general relativity. Particular emphasis will be placed on establishing connections between different approaches and providing, to the extent possible, a unifying description of black hole interiors.
Thursday
Link between foundational and phenomenological aspects
16/07/2026
Modifying characteristic features of black holes, such as removing the singularities occurring in general relativity, can result in new instabilities and phenomenology. We will discuss how to leverage these effects to possibly enable feedback between theory and experiment.
Friday
Challenges ahead
17/07/2026
We will wrap up the workshop by identifying the most pressing key challenges and discussing how to overcome them. Talks and discussion sessions will allow us to either revisit challenges that had been discussed in previous days, or bring up challenges that may not have been discussed so far.
