Yes, that's three thousandths of a degree above absolute zero.

是的， 那是绝对零度以上千分之三度。

Absolute zero is the temperature at which all movement of all particles stops.

绝对零度，是指粒子的所有热运动都完全停止。

And here is what would happen if you touch absolute zero.

我们一起来看看，你触及绝对零度会怎样。

It's so cold at absolute zero that the very atoms have stopped moving.

绝对零度冷到原子都停止了运动。

Near absolute zero, the quantum vortices in ultra-cold, ultra-thin superconductor materials were arranged in pairs.

在接近绝对零度时，超冷超薄超导体材料中的量子涡会成对排列。

Well, it's...it's possible at absolute zero, but we would have to remove the temperature restrictions.

这东西... 只适用于绝对零度，但我们得想办法解决温度的限制。

If we reduce temperature enough that atoms themselves are totally still, that's absolute zero.

温度降低到原子完全静止的程度，那就是绝对零度。

You might think that would happen at absolute zero, the coldest possible temperature.

你可能认为 在绝对零度时这有可能发生，在可能到达的最低温度下。

So absolute zero is colder than the dark reaches of outer space.

所以绝对零度比外太空的黑暗地带还要冷。

Well, how about negative 273 degrees, 'cause that's the temperature at which entropy reaches its minimum value.

大概有零下273度（绝对零度）热力学函数因为那是熵达到其最小值时的温度。

This is a liquid helium tank, it's cold enough — it's at 4 kelvin, 4 degrees above absolute zero.

这是一个液氦罐，已经足够冷了——温度是 4 开尔文，比绝对零度高 4 度。

Now, let's say we froze a small piece of metal down to absolute zero temperature.

现在，我们假设把一小块金属冷冻到绝对零度。

So, besides sounding like an awesome band's name, absolute zero is the lowest possible temperature in the Universe.

所以，除了听起来像个酷乐队的名字之外，绝对零度是宇宙中可能的最低温度。

Yeah, that's not as cold as absolute zero.

是的，这还没有绝对零度那么冷。

And today, you get to be our guinea pig, and touch something cooled down to absolute zero.

今天，你将成为我们的小白鼠，触摸被冷却到绝对零度的东西。

Well, hopefully, the study of absolute zero temperature will lead to discoveries in cryogenic research.

好吧，希望对绝对零度温度的研究能带来低温研究的新发现。

We can begin our journey at -273.15 degrees Celsius also known as absolute 0 or the coldest possible temperature in the universe.

我们可以从零下 273.15 摄氏度开始我们的旅程，它也被称为绝对零度或宇宙中最冷的温度。

At absolute zero, the piece of metal will lower your cells' temperature until they are so cold that the liquid inside them freezes.

在绝对零度的情况下，这块金属会降低你细胞的温度，直到细胞内的液体冷到结冰。

And the temperature that color corresponds to is 2.7 Kelvin, that's just 2.7 degrees above absolute zero, the coldest that anything can be.

这个颜色对应的温度是 2.7 开尔文，只比绝对零度高 2.7 度，这是所有温度中最冷的。

But while we've managed to get within a fraction of a billionth of a degree, no one has ever actually cooled anything to absolute zero.

但是尽管我们已经成功地将温度控制在十亿分之一度以内，但还没有人真正将任何东西冷却到绝对零度。
