But the proposal that really excites me is the  Laser Interferometer Space Antenna, or LISA.

但真正令我兴奋是激光干涉仪太空天线（LISA）。

Yeah, using an interferometer to create what is...

是 使用干涉仪来创建。

No. No, the impact of interferometers on 3D renderings.

不 不 是干涉仪在三维渲染中影响。

This is essentially  what the interferometer measures with light.

这本质上就是干涉仪用光测量内容。

And the larger and more powerful the  interferometer, the more sensitive it is.

干涉仪大、功能强，它灵敏度就高。

Remember what we said, with interferometers,   bigger is better!

请记住我们所，对于干涉仪来，大好！

But in reality, the interferometer is constantly picking up noise.

但实上，干涉仪不断地拾取噪声。

This squeezing  minimizes the light's phase noise and squeezes it into amplitude noise, which the interferometer  doesn't measure.

这种挤压最大限度地减少了光相位噪声，并将其挤压成干涉仪无法测量噪声。

LIGO is essentially a  large-scale and very sensitive interferometer, an invention that's been around since the 1880s.

LIGO 本质上是一个大型且非常灵敏干涉仪，这项发明自 1880 年代就已存在。

An interferometer essentially measures what happens when light waves are combined from two  or more sources.

干涉仪本质上是测量当两个或多个光源光波组合时会发生什么。

For example, you could use an interferometer to test whether light travels at  different speeds through different substances, such as through air or water.

例如，您可以使用干涉仪来测试光是否以不同速度穿过不同物质（例如空气或水）。

Any particles in the  interferometer's arms are also a problem, which is why LIGO pumps the air from its vacuum chambers  to one trillionth of atmospheric pressure.

干涉仪臂中任何颗粒也是一个问题，这就是为什么 LIGO 将真空室中空气抽至万亿分之一大气压原因。

This interferometer would be so big and so precise, scientists hope  it would be adept at uncovering exotic and theoretical sources of gravitational waves, such  as cosmic strings and other speculative phenomena.

这个干涉仪将是如此之大和如此精确，科学家希望它能够擅长揭示引力波奇异和理论来源，例如宇宙弦和其他推测现象。

NANOGrav have cleverly concocted  an imaginary interferometer that stretches for thousands of light  years, and all we need to use it are the good old radio telescopes  we have been using for decades.

NANOGrav 巧妙地炮制了一个延伸数千光年假想干涉仪，而我们需要使用它只是我们已经使用了几十年老式射电望远镜。

Michelson talked Alexander Graham Bell, newly enriched inventor of the telephone, into providing the funds to build an ingenious and sensitive instrument of Michelson's own devising called an interferometer, which could measure the velocity of light with great precision.

迈克尔逊服新近富有电话发明者亚历山大·格雷厄姆·贝尔 （Alexander Graham Bell） 提供资金，以制造一种由迈克尔逊自己设计巧妙而灵敏仪器，称为干涉仪，它可以非常精确地测量光速。
