Entropic Gravity: Information, Entropy, and the Emergence of Space-Time

In this Science Corner episode, we explore the audacious idea that gravity might not be fundamental but emergent from quantum information and entropy. We trace the arc from black hole thermodynamics to holography and entanglement, then outline a quantum relative-entropy action that compares a background topological metric with a matter-induced metric. We’ll see how topological fields and the Hodge-Rack operator yield a dressed Einstein–Hilbert action with an emergent cosmological constant, and how a scalar-field warm-up recovers familiar equations in the appropriate limit. Join us for a guided tour of how information theory could shape our understanding of space, time, and gravity—without getting lost in the math.
