Insights from Quantum Foundations into Black Holes
Black holes provide a testing ground for the interplay between General Relativity and quantum theory, as seen in phenomena like Hawking radiation. Yet this interplay gives rise to deep puzzles — famously, the “firewall paradox”, in which the predictions made by an infalling observer and an outside observer, when combined, lead to a contradiction.
In this talk, I will argue that recent advances in quantum foundations suggest an unexpected resolution: the paradox may not reflect a clash between General Relativity and quantum theory, but instead point to quantum theory’s limitations in consistently describing scenarios involving multiple observers with different perspectives.
