You learn in science that black holes formed when stars collapsed and that they have such incredibly intense gravity that not even light can escape them, at least that`s the theory.

在科学课上,我们学习过黑洞是恒星在核聚变反应的燃料耗尽而死亡后而形成的。黑洞的引力场极为强劲,按照理论上,甚至于光速也不能逃脱黑洞的引力,

There is some controversy over whether black holes actually exist. Some scientists, including Stephen Hawking, have said they don`t. Others argue they`re mathematically impossible.

但是关于是否存在黑洞,有一些争议。史蒂芬·霍金等一些科学家,称黑洞不存在。其他的科学家则认为在数学层面上黑洞是不可能存在的。

Those who disagree with that say that not only are they real, but that two of them are about to collide.

而持反对意见的人认为黑洞不仅仅存在,而且其中有两个黑洞即将要发生碰撞。

Black holes are some of the strangest and most mysterious object in space. Scientists say they have found new clues that two black holes might be merging, a phenomenon some consider the Holy Grail of physics.

黑洞是属于宇宙中最强劲、最神秘的物体。科学家称,已经发现新的线索证明两个黑洞可能将要合并,有些人将这一现象称为物理学的“圣杯”。

NASA says two of its space telescopes have found new information about an odd repeating light signal coming from the center of a distant galaxy in the Virgo constellation, about 3.5 billion light years from Earth.

美国宇航局称两台天文望远镜发现了处女座中一个遥远的星系一直重复发出光信号,距离地球约35亿光年。

Researchers say the new data is the best evidence yet that the light signal is coming from two super massive black holes and that the duo is orbiting closer together than any pair detected so far. Scientists were able to track the changing light patterns over the past 20 years, using ultraviolent data from Hubble and the Galaxy Evolution Explorer.

研究人员称新数据是最好的证据表明光信号来自于两个超大质量的黑洞,这是目前为止侦测的距离最近的两个黑洞。科学家们能利用哈勃望远镜以及星系演化探测器跟踪过去20年的光模式的转变。

The two black holes are expected to collide and merge in less than a million years, triggering a huge explosion.

预计这两大黑洞将会在未来100年发生碰撞并合为一体,引发巨大的爆炸。

Why all the interests in black hole mass up? For the most part, black holes are a huge mystery. Scientists think there are billions of them in the universe. But they can`t actually see them. Experts say they can detect gas and other materials being sucked into the black holes.

为什么人们都关注黑洞质量呢?大部分原因是由于黑洞是一个巨大的谜团。科学家认为宇宙中存在数十亿的黑洞。但是科学家们无法看到这些黑洞。专家称,自己可以侦测到被黑洞吸进的气体和其他物质。

In the final moments before they collide, it`s predicted the black holes will cause ripples in the space and time called gravitational waves. And scientists say those waves could hold clues about the fabric of our universe.

人们预测,在黑洞碰撞的最后时刻,会引发时空的波动,即引力波。同时科学家还表明,这些引力波中含有我们宇宙结构的信息。
