Title: Quantum Black Holes and the Conundrum of Cosmic Causality

Abstract:
How does causality work in a quantum spacetime? Is it merely a coincidence that whenever we require quantum gravity to understand phenomena—such as black hole evaporation or the Big Bang—we also encounter causal paradoxes like the black hole information paradox or the cosmological horizon problem? I will explore what we can learn about causality from studying quantum black holes and how these findings could guide us on the roadmap to discovery in future astronomical observations.
