研究人員證實：宇宙膨脹速度超出預期
Universe Expanding Faster Than Expected, Researchers Confirm
宇宙的膨脹速度超出了我們目前最佳理論的預測，這項謎團被天文學家稱為「哈伯張力」(ㄏㄚ ㄅㄛˊ ㄓㄤ ㄌㄧˋ)。
The universe is growing faster than our best theories predict, a mystery known to astronomers as the [Hubble tension|noun].
這種衝突源於測量「哈伯常數」(ㄏㄚ ㄅㄛˊ ㄔㄤˊ ㄕㄨˋ)的兩種方式，該常數用於描述宇宙的膨脹速率。
This conflict arises from two ways of measuring the [Hubble constant|noun], which tells us the rate of cosmic expansion.
第一種方法是利用恆星和超新星等「標準燭光」(ㄅㄧㄠ ㄓㄨㄣˇ ㄓㄨˊ ㄍㄨㄤ)來觀測鄰近星系，得出的膨脹率約為每秒每百萬秒差距73.5公里。
The first method observes nearby galaxies using [standard candles|noun] like stars and supernovae, finding an expansion rate of about 73.5 km/s/Mpc.
第二種方法則是利用源自大霹靂殘留下來的「宇宙微波背景」(ㄩ ㄓㄡˋ ㄨㄟ ㄅㄛ ㄅㄟˋ ㄐㄧㄥˇ)，該方法預測的速率較慢，約為每秒每百萬秒差距67至68公里。
The second method uses the [Cosmic Microwave Background|noun], a relic from the Big Bang, which predicts a slower rate of 67–68 km/s/Mpc.
近期一項重大研究證實，這種差異並非測量誤差，而是一種真實的「物理現象」(ㄨˋ ㄌㄧˇ ㄒㄧㄢˋ ㄒㄧㄤˋ)。
Recently, a major study confirmed this discrepancy is not a measurement error but a true [physical phenomenon|noun].
隨著統計顯著性超過五個標準差，科學家現在一致認為我們現有的宇宙學標準模型可能並不完整。
With a statistical significance exceeding five standard deviations, scientists now agree that our standard model of cosmology is likely incomplete.
這場「危機」暗示我們需要「新物理」來解釋宇宙。
This "crisis" suggests we need "new physics" to explain the universe.
研究人員目前正在探索諸如「早期暗能量」(ㄗㄠˇ ㄑㄧ ㄢˋ ㄋㄥˊ ㄌㄧㄤˋ)或未知的基本粒子等理論，以彌補這一差距。
Researchers are now exploring theories like [Early Dark Energy|noun] or unknown fundamental particles to bridge this gap.
展望未來，新一代的觀測站對於理解我們的基礎重力定律是否需要進行重大修正，或者宇宙背後是否有隱藏的深層力量在驅動，將至關重要。
As we look to the future, next-generation observatories will be essential to understanding whether our fundamental laws of gravity need a major revision or if there is a deeper, hidden force driving our cosmos.
