A bold new theory suggests gravity might emerge from entropy, hinting at a link between quantum physics and spacetime — and maybe even solving dark matter and dark energy riddles.
Since 1915, general relativity ruled gravity. But as 95% of the universe remains "dark", physicists like Ginestra Bianconi think it's time to rethink what gravity even is.

For a century, physicists struggled to unite Einstein’s gravity with quantum physics. Now, quantum relative entropy might be the missing link to explain gravity’s quantum roots.
Bianconi proposes that spacetime itself could act like a quantum operator, rewriting Einstein's equations to allow gravity to emerge from entropy — and potentially from information itself.

If Bianconi’s model is right, her predicted "G-field" could explain dark matter, and her cosmological constant could naturally account for dark energy’s push on cosmic expansion.
The theory hints at hidden fields shaping galaxies and cosmic structure — forces we call dark matter and dark energy — possibly arising from deeper quantum-entropic laws.

Unlike other theories, Bianconi’s framework predicts a small cosmological constant that matches what astronomers see as dark energy's hand in the universe's accelerated expansion.

Though general relativity works perfectly for stars and black holes, Bianconi's math suggests gravity may shift at quantum scales, giving us a first step toward a unified theory.

Could quantum gravity from entropy finally unite the colossal and the tiny — black holes and quarks? If so, Bianconi's work may edge us closer to a long-sought "theory of everything."
