## Resource

The holographic principle suggests that all the information contained in a three-dimensional volume may be encoded on a two-dimensional boundary. The idea emerged from black hole physics, where entropy scales with surface area rather than volume. Building on the Maldacena conjecture, which links gravity in higher dimensions to quantum field theories in lower ones, this duality reframes the black hole information paradox and the nature of spacetime itself. In this episode, we explore the possibility that physical reality emerges from quantum information—and what that means for cosmology and quantum computing. This episode includes AI-generated content.
