伦敦玛丽皇后大学数学家Ginestra Bianconi提出了一项新的量子引力理论，旨在解决宇宙如何在遵守热力学第二定律约束下产生复杂结构这一根本问题1。该理论采用"从熵引出引力"的量子引力框架，通过引入量子几何相对熵等概念，揭示了宇宙膨胀过程中熵分布的关键机制1。
根据这一理论框架，虽然宇宙总熵随着空间膨胀而持续增加，但单位体积内的熵实际上呈现下降趋势1。这种局部熵的减少为星系、恒星、行星乃至生命的形成和演化提供了物理基础1。Bianconi表示："这项工作揭示了从熵引出引力理论如何能够处理协调热力学第二原理与宇宙复杂性出现的挑战性问题"1。相关研究已发表于《物理评论D》期刊2026年第114卷第2期1。
Mathematician Ginestra Bianconi at Queen Mary University of London has proposed a novel theoretical framework addressing a fundamental cosmological paradox: how the universe can generate complex structures while obeying the second law of thermodynamics 1. The theory, based on a quantum gravity model termed "gravity emerges from entropy," suggests that although total entropy in the universe increases with cosmic expansion, entropy per unit volume actually decreases, creating the conditions necessary for galaxy, star, planet, and life formation 1.
The research, published in Physical Review D, Volume 114, Issue 2 in 2026, employs quantum geometric relative entropy (QGRE) and the Friedmann-Robertson-Walker spacetime model to reconcile this apparent contradiction 1. According to Bianconi, "This work reveals how the theory of gravity emerging from entropy can address the challenging question of reconciling the second principle of thermodynamics with the emergence of complexity in the universe" 1. The study demonstrates that while the universe's total entropy grows, the density of entropy within any given spatial volume declines, thereby permitting the emergence of ordered structures throughout cosmic history 1.
