Scientists look for dark matter around our Sun and find none. Uh-oh.

There’s troubling news in the world of astrophysics, in which astronomers can’t seem to find the dark matter.
在天體物理學世界有令人不安的消息，內裡的天文學家似乎不能找到暗物質。
As you may know dark matter is a much-speculated upon, but unknown substance that cannot be seen but appears to exist as it exerts a gravitational force on material around it. Astronomers first posited the existence of dark matter to explain why the outer portions of galaxies rotate quickly, and it now is also an important part of theories that explain how galaxies form and grow.
正如你可能知道暗物質是一很大程度推測、但不明的物質，它不能被看到但似乎存在，因為它施加引力在物質的周圍。天文學家首先假定暗物質的存在，來解釋為什麼星系的外層部分快速旋轉，及現在它亦是一個理論的重要部分，去解釋星系如何形成和成長
Scientists believe there must be about five times as much dark matter in the universe as normal matter — atoms, planets, you and me.
科學家們相信，在宇宙中暗物質必須是正常物質 - 原子、行星、你和我 - 的五倍左右。
Last week, in a study that didn’t get the attention it probably deserves, astronomers said they could find no dark matter near our Sun.
上週在一項沒有得到它應得重視的研究中，天文學家說他們在我們的太陽附近找不到暗物質。
這藝術家的印象顯示銀河系、研究範圍和預計的暗物質光暈。 （歐洲南方天文台/ L斜巷）
Existing theories predict that the average amount of dark matter in the Sun’s part of the galaxy should be in the range 1 to 2 pounds of dark matter in a volume the size of the Earth. The new measurements found nada. Zip. Zilch.
“This is an article that we are going to have to take seriously,” Texas A&M astronomer Nick Suntzeff told me.
Which is to say that if dark matter is not where our theories predict it will be, our theories probably have some serious issues.
那是說如果暗物質並不在我們理論所預測會在之處，我們的理論可能有一些嚴重的問題。
