Something in the Universe is creating more mass than we can detect directly.
宇宙中的某些東西正在創造更多的品質，我們無法直接探測到。
We know it's there because of its gravitational effect on the stuff we can detect; but we don't know what it is, or how it got here.
我們知道它的存在是因為它對我們可以探測到的東西產生了引力效應；但我們不知道它是什麼，或者它是如何來到這裡的。
We call that invisible mass "dark matter", and physicists have just identified a particle that could be behind it.
我們把這種看不見的物質稱為“暗物質”，物理學家們剛剛發現了一種可能在其背後的粒子。
The candidate culprit is a recently discovered subatomic particle called a d-star hexaquark.
候選罪魁禍首是最近發現的一種名為d星六夸克的亞原子粒子。
And in the primordial darkness following the Big Bang, it could have come together to create dark matter.
在大爆炸之後的原始黑暗中，它可能聚集在一起創造暗物質。
For almost a century, dark matter has perplexed astronomers.
近一個世紀以來，暗物質一直困擾著天文學家。
It was first noticed in the vertical motions of stars, which hinted that there was more mass around them than what we could see.
它最初是在恆星的垂直運動中被注意到的，這暗示著它們周圍的品質比我們所能看到的更多。
We can now see the effect of dark matter in other dynamics, too - in gravitational lensing, for instance, wherein light bends around massive objects such as galaxy clusters; and the outer rotation of galactic discs, which is too fast to be explained by visible mass.
我們現在也可以在其他動力學中看到暗物質的影響-例如，在引力透鏡中，光在大品質物體(如星系團)周圍彎曲；以及銀河盤的外旋轉，這太快了，無法用可見品質來解釋。
Dark matter has, so far, proven impossible to detect directly, as it neither absorbs, emits, nor reflects any kind of electromagnetic radiation.
到目前為止，暗物質被證明是不可能直接探測到的，因為它既不吸收，也不發射，也不反射任何種類的電磁輻射。
But its gravitational effect is strong - so strong that as much as 85 percent of the matter in our Universe could be dark matter.
但它的引力效應很強-如此強烈，以至於我們宇宙中多達85%的物質可能是暗物質。
Scientists would very much like to get to the bottom of the dark matter mystery, though.
儘管如此，科學家們非常想弄清暗物質之謎的真相。
It's not just because they're very nosy - figuring out what dark matter is could tell us a lot about how our Universe formed, and how it works.
這不僅僅是因為他們非常愛管閒事-弄清楚什麼是暗物質可以告訴我們很多關於我們的宇宙是如何形成的，以及它是如何工作的。
If dark matter doesn't actually exist, that would mean there's something very wrong with the standard model of particle physics we use to describe and understand the Universe.
如果暗物質實際上並不存在，那就意味著我們用來描述和理解宇宙的粒子物理學的標準模型是非常錯誤的。
