A new theoretical study using a quantum gravity framework called Gravity from Entropy proposes that the Universe's total entropy increases as space expands, while entropy per unit volume decreases. This mechanism could explain how complex structures like galaxies, stars, and life can emerge locally without violating the second law of thermodynamics. Mathematician Ginestra Bianconi developed this framework to reconcile cosmic expansion with the formation of ordered structures.
Why it matters
This theory addresses a fundamental puzzle in cosmology about how increasing complexity in the Universe is compatible with thermodynamic laws. If validated, it could provide new insights into the relationship between quantum gravity, dark energy, and the conditions that allow life to exist.
Understand the Science
A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second law of thermodynamics. Using a quantum gravity framework called Gravity from Entropy, mathematician Ginestra Bianconi found that the Universe’s total entropy may rise as space expands, even while entropy within each unit of volume falls. That decline could leave room for galaxies, stars, planets, and life to form locally amid an overall increase in cosmic entropy.
