新理論將量子重力與宇宙膨脹聯繫起來
New theory links quantum gravity to the expansion of the universe

數十年來，物理學一直被兩個相互衝突的支柱所分裂：廣義相對論，它統治著重力與浩瀚的宇宙；以及量子力學，它描述亞原子粒子的行為。
For decades, physics has been split between two conflicting pillars: General Relativity, which governs gravity and the vast cosmos, and Quantum Mechanics, which describes the behavior of subatomic particles.
當科學家嘗試合併這些框架時，他們往往會撞上一堵無法解開的數學無限之牆。
When scientists try to merge these frameworks, they often hit a wall of unsolvable mathematical infinities.
然而，一項新理論正透過將量子重力與宇宙膨脹連結起來，縮小這道鴻溝。
However, a new theory is bridging this gap by linking quantum gravity to the expansion of our universe.
宇宙學中最大的難題之一是宇宙常數——即真空的能量密度。
One of the biggest puzzles in cosmology is the cosmological constant—the energy density of empty space.
若非存在這種差異，宇宙膨脹的速度將過快，以致無法形成星系。
Without this discrepancy, the universe would have expanded too quickly for galaxies to form.
新興研究（例如涉及時空「彈性」的模型，或是類比量子霍爾效應的模型）顯示，量子重力效應或許能穩定這個常數。
Emerging research, such as models involving space-time 'elasticity' or analogies to the quantum Hall effect, suggests that quantum gravitational effects might stabilize this constant.
透過更深入理解重力在量子層級上的運作方式，研究人員希望能解決「哈伯張力」——即我們在測量宇宙膨脹率時所遇到的衝突。
By better understanding how gravity functions on a quantum level, researchers hope to solve the 'Hubble Tension'—a conflict in how we measure the universe’s expansion rate.
隨著科學家研究宇宙微波背景以尋找這些效應的證據，我們正逐漸接近「萬有理論」，這是一個最終能將微觀與宏觀物理學統一起來的單一框架。
As scientists study the cosmic microwave background for evidence of these effects, we move closer to a 'Theory of Everything,' a singular framework that could finally unify the physics of the tiny and the massive.
