Astronomers Find Universe Expanding Faster Than Predicted
天文學家發現宇宙膨脹速度高於預期
For nearly a century, astronomers have known that our universe is expanding.
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。
However, a major debate has recently emerged among scientists called the "Hubble tension."
然而，科學界近來出現了一項重大爭論，稱為「哈勃張力」。
This term refers to a persistent disagreement regarding the speed of this expansion, known as the Hubble constant.
此詞彙意指對於膨脹速度（即哈勃常數）的持續分歧。
Scientists using two different methods have calculated conflicting results.
使用兩種不同方法的科學家計算出了相互衝突的結果。
Observations of the early universe, based on the Cosmic Microwave Background, suggest an expansion rate of about 67–68 km/s/Mpc.
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。
Conversely, measurements of the local universe using "standard candles" like distant supernovae suggest a faster rate of 73–74 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。
Because these measurements have become increasingly precise, experts believe the gap is not simply a measurement error.
由於這些測量結果日益精確，專家認為該差距並非單純的測量誤差。
The discrepancy could point toward new physics, such as unknown subatomic particles or previously misunderstood effects of dark energy.
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。
