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.
