Not to be confused with gravitational waves.

不要和引力波混淆。

So what was needed to detect gravitational waves?

所以探测引力波需要什么？

That’s why detecting gravitational waves is so significant.

这就是为什么引力波探测对我们如此重要。

There are gravitational wave detectors spread across the world.

全球各地都有引力波探测器。

China has sent two satellites for the detection of gravitational waves into planned orbit.

中国已将两颗用于探测引力波的卫星送入预定轨道。

Fluctuations in the gravity coming from the universe are called gravitational waves.

宇宙中传来的引力的波动，就是所谓的引力波。

They do it by rippling this space with gravitational waves.

它们通过引力波在周围空间激起涟漪似的波纹。

So nano hertz is the gravitational waves frequency that we're looking at.

“纳赫兹”就是我们正在寻找的引力波频率。

Chinese scientists have found key evidence for the existence of nanohertz gravitational waves.

中国科学家发现了纳赫兹引力波存在的关键证据。

What would a gravitational wave feel like?

引力波会让人产生什么感觉呢？

And that's the gravitational waves that we're looking for.

这种情况，就是我们在寻找的引力波。

Albert Einstein predicted gravitational waves over a hundred years ago.

爱因斯坦在一百多年前就预测到了引力波。

So the trouble with gravitational waves is that they're very weak; they're preposterously weak.

研究引力波的难点在于它们太微弱了； 微弱得不合常理。

So let me take a moment to tell you what I mean by a gravitational wave.

现在让我来简单介绍一下 什么是引力波。

It can ripple with gravitational waves. And it can expand, creating more and more space in space.

它可以因重力波影响而震动，也可以膨胀，在两个物件之间创造出更多的空间。

Not in a massive cosmic explosion, but a silent merger, sending powerful gravitational waves throughout the Universe.

相撞并不会引发大规模的宇宙爆炸，而是一次静默的融合，散发强大的引力波能穿过整个宇宙。

The excess energy from the collision would be expelled back into the Universe as gravitational waves.

这次碰撞产生的多余能量会以引力波的形式返回到宇宙空间里。

Acceleration of massive objects disturbs the surrounding space-time and produces " ripples" which are known as gravitational waves.

大质量物体的加速扰乱周围的时空并产生“涟漪”，即引力波。

I'm in a building that contains a 1 to 100 scale of LIGO, the gravitational wave detector.

我现在所处的建筑，有一个百分之一尺寸的Ligo引力波探测器。

Researchers hope this triple-black-hole system may be a good place to look for space-time ripples called gravitational waves.

研究人员希望在这个三个黑洞系统中，可以发现时光涟漪，专业上叫做重力波。
