Is Gravity Just Spacetime's Temperature?
Why This Debate Matters Contemporary physics faces a quiet but profound crisis. Our picture of the universe rests on two extraordinary frameworks that do not fit neatly together: General Relativity (GR), which describes spacetime as a smooth continuum curved by mass, and Quantum Mechanics (QM), which describes reality as discrete particles governed by chance. That tension sits alongside another stubborn cosmic puzzle: if the second law of thermodynamics dictates that the universe must become increasingly disordered over time, how can an expanding cosmos give rise to complex, ordered structures like galaxies, stars, planets, and life? Standard cosmology often attributes cosmic acceleration to a static cosmological constant or an undetected form of dynamical dark energy. Gravity from Entropy (GfE), developed by mathematician Ginestra Bianconi , offers a fresh perspective. Rather than adding missing particles or modifying GR arbitrarily, GfE treats gravity as an emergent, thermo...
