And as it cools even further all the emitted radiation, all of that light is in colors that we can't see.

当它进一步冷却发出辐射时，此时的光就不是可见光了。

The oven emits microwave radiation, which is absorbed by the molecules, especially those of water.

微波炉放射出电磁波 被分子吸收，尤其易被液体吸收。

Curie soon found that the element thorium emitted similar radiation.

居里很快发现元素钍会发出类似的辐射。

This temperature is known as the Planck Temperature because the radiation emitted from an object this hot would have a wavelength equal to the Planck Length.

这个温度被称为普朗克温度，因为从这么热的物体发出的辐射，其波长等于普朗克长度。

So black holes ought to emit radiation.

所以黑洞应该发射辐射。

After this stage, UV lamps are plunged into the water, emitting radiation that permanently damages the genetic material of any lingering life forms.

在这一阶段后，紫外线灯被置入水中，释放出的辐射会永久性地破坏任何残留的生命形式的遗传物质。

This causes them to emit radiation that we can read here on Earth.

这导致它们发出辐射, 我们可以在地球上阅读。

But a body with a particular temperature must emit radiation at a certain rate.

但是具有特定温度的物体必须以特定速率发射辐射。

In the following years, physicists Pierre and Marie Curie discover other elements that also naturally emit radiation.

在接下来的几年里， 物理学家皮埃尔和玛丽·居里发现了其他也会自然发出辐射的元素。

You and I are emitting radiation right now, but it's down in the infrared… because we're so coooool.

你和我现在正在发射辐射，但它在红外线以下… … 因为我们太酷了。

If antimatter collides with particles of the right matter, they completely annihilate each other, that is they cancel each other out while emitting powerful radiation.

如果反物质与正物质的粒子相撞，它们会完全相互湮灭，也就是说，它们在发射强大辐射的同时相互抵消。

Warm objects emit infrared radiation, which should pass back out into space, because most atmospheric gases don't absorb it.

温暖的物体发出红外线辐射，应该传回太空，因为大多数大气气体不吸收它。

Thankfully, modern LCD TVs don’t emit harmful radiation at all, so you can sit as close as you want.

值得庆幸的是，现代液晶电视根本不会发出有害辐射，因此您可以坐得离自己近一些。

Such black holes would have a much higher temperature and would be emitting radiation at a much greater rate.

这样的黑洞会有更高的温度，并且会以更快的速度发射辐射。

First of all, most black holes accrete, or absorb matter and energy, more quickly than they emit Hawking radiation.

首先，大多数黑洞吸积或吸收物质和能量的速度比它们发射霍金辐射的速度更快。

In the 1970s, Hawking proposed that black holes could emit radiation due to quantum mechanical effects near the event horizon.

20 世纪 70 年代，霍金提出黑洞可以由于事件视界附近的量子力学效应而发射辐射。

" I mean, you're holding a device that emits radiation right next to your brain." " Terrible idea, right? Well, no."

“我的意思是，你拿着一个可以在你的大脑旁边发射辐射的设备。” “糟糕的主意，对吧？好吧，不。”

See, in their research, they used something called the Cosmic Microwave Background, which is the emitted radiation dating back to 400,000 years after the Big Bang.

看， 在他们的研究中， 他们使用了一种叫做宇宙微波背景的东西，它是大爆炸后 40 万年发出的辐射。
