Bianconi Proposes Entropy-Based Gravity Solution to Cosmic Paradox in 2026 Physical Review D Study

Summary
Physical Review D published Ginestra Bianconi’s 16 July 2026 study arguing that Gravity from Entropy can reconcile rising universal entropy with the emergence of galaxies, stars, planets and life.
The paper finds total cosmic entropy increases as the Universe expands, while entropy per unit volume falls—a split that could allow local order to grow without violating thermodynamics.
In the theory, gravity emerges from information-theoretic tension between two spacetime metrics, quantified by Quantum Geometric Relative Entropy; at low energies its equations reduce to general relativity.
Under stronger curvature, the framework departs from Einstein’s theory and produces a time-varying dark-energy term, potentially giving physicists a way to test the idea.
The proposal remains an early theoretical framework, but Bianconi says it could help bridge thermodynamics, quantum mechanics, cosmology and the origin of complexity.
