This article explores the Gravity From Entropy (GfE) theory's assertion that total universal entropy increases over time while local volume entropy decreases, offering a statistical mechanics foundation for gravity without relying on traditional holographic assumptions. The work advances fundamental theoretical physics by unifying GfE cosmologies with general relativity within a thermodynamic framework and deriving key results like the Schwarzschild black hole area law from first principles.

GfE Theory Shows Total Universe Entropy Increases Over Time

Quantum ZeitgeistJuly 20, 20264 min read

It is generally believed that the early Universe corresponds to a state of small entropy and that the Universe evolves toward a high entropy configuration, though a consensus on quantifying the geometric degrees of freedom reconciling this picture with gravity is still missing. The Gravity From Entropy (GfE) theory posits that gravity is a statistical mechanics theory capturing information in the interplay between spacetime and matter fields, showing the total entropy of the Universe increases with time.

The Gravity From Entropy (GfE) theory demonstrates that while total entropy universally increases with time, entropy per unit volume actually decreases. This counterintuitive finding reframes our understanding of gravity, not simply as related to statistical mechanics, but as fundamentally being a statistical mechanics theory, capturing information from the interplay of spacetime geometry and matter fields. Researchers are developing the thermodynamics of GfE for homogeneous and isotropic spacetimes, and framing both GfE cosmologies and general relativity within a…
