A few years ago, FQxI funded Adam R. Brown through a Zenith Grant for Complexity, Black Holes, and Observers. The aim was to show that maybe the real barrier in the black-hole information puzzle is computational, not a breakdown of physics. If recovering the message demands resources that blow up exponentially, the ‘experiment’ may be out of reach in practice.
Since then Brown and collaborators introduced Python’s Lunch, a wormhole geometry where a central bulge flags exponentially hard decoding of Hawking radiation. It gives a spacetime picture of the complexity roadblock and builds on earlier foundations like Complexity = Action and the Second Law of Quantum Complexity, which treat complexity as a physical resource that tends to grow.
