天文學家發現宇宙膨脹速度高於預期
Astronomers Find Universe Expanding Faster Than Predicted
近一個世紀以來，天文學家早已知悉我們的宇宙正處於膨脹狀態。
For nearly a century, astronomers have known that our universe is expanding.
然而，科學界近來出現了一項重大爭論，稱為「哈勃張力」。
However, a major debate has recently emerged among scientists called the "Hubble tension."
此詞彙意指對於膨脹速度（即哈勃常數）的持續分歧。
This term refers to a persistent disagreement regarding the speed of this expansion, known as the Hubble constant.
基於宇宙微波背景輻射對早期宇宙的觀測，顯示膨脹速率約為每秒每百萬秒差距67至68公里。
Observations of the early universe, based on the Cosmic Microwave Background, suggest an expansion rate of about 67–68 km/s/Mpc.
反之，利用遠方超新星等「標準燭光」對鄰近宇宙進行的測量，則顯示較快的速率，即每秒每百萬秒差距73至74公里。
Conversely, measurements of the local universe using "standard candles" like distant supernovae suggest a faster rate of 73–74 km/s/Mpc.
相反地，這場「哈勃危機」暗示我們的宇宙學標準模型可能並不完備。
Instead, this "Hubble crisis" suggests that our standard model of cosmology might be incomplete.
這項差異可能指向新的物理學，例如未知的亞原子粒子或過去被誤解的暗能量效應。
The discrepancy could point toward new physics, such as unknown subatomic particles or previously misunderstood effects of dark energy.
雖然研究人員持續利用重力波偵測等先進工具交叉比對數據，但科學界對於這些發現可能導致對宇宙定律進行根本性改寫的可能性感到興奮不已。
While researchers continue to cross-check their data with advanced tools like gravitational wave detection, the scientific community remains excited by the possibility that these findings could lead to a fundamental rewrite of the laws governing our cosmos.
