So as you travel deeper, the buoyancy force from the metallic hydrogen counteracts gravity's downward pull.

所以当你下降得更深，来自金属氢的浮力，抵消掉向下的重力。

Hydrogen molecules are forced so close together that their electrons break loose, forming an unusual substance called metallic hydrogen.

氢分被紧紧地压在一起，从而使电挣脱形成一种叫做金属氢的特殊物质。

Metallic hydrogen would be a huge deal.

金属氢将是一件大。

Metallic hydrogen will begin to form, and you'll be surrounded by it.

金属氢将开始形成， 你将被它包围。

Like Jupiter, it probably has a rocky core several times the mass of Earth, surrounded by layers of ice and weird, metallic hydrogen.

就像木星，土星可能有一个比地球质量大几倍的岩石内核，被冰层和特的金属氢所包围。

In the meantime, we can’t say for sure that they’ve created metallic hydrogen.

与此同时，我们不能肯定地说它们已经产生了金属氢。

And into that liquid metal we inject a high temperature plasma of hydrogen.

我们向液态金属中注入高温氢等。

Metallic hydrogen is highly reflective, so if you tried using lights to see down there, it would be impossible, and it's as dense as a rock.

金属氢具有高反射性，因此尝试用灯光看看下面，是不可能的，并且它像石头一样稠密。

Jupiter is still warm from its formation, and has an interior that's mostly metallic hydrogen, and it may not even have a core.

木星在形成时仍然是温暖的，它的内部主要是金属性氢，并且可能甚至可能没有内核。

At a depth of 40,234 kilometers or 25,000 miles, it will compress so strongly that it will become harder and denser than rock, turning into so-called metallic hydrogen.

在 40,234 公里（2万5千英里）的深度，它会受到强烈的压缩，变得比岩石更硬，密度更大，变成所谓的金属氢。

But back in 1935, physicists predicted that the right conditions — specifically, very high pressures — could force hydrogen into becoming a metal.

但早在 1935 年，物理学家就预测，合适的条件——特别是非常高的压力——可能会迫使氢变成金属。

But if you somehow made it around a third of the way down, where the pressure is more than 100 gigapascals, you'd find metallic hydrogen, which continues all the way to the core.

但是如果用某种方式将压强降低至其三分之一，也就是100兆帕以上，你就会发现金属氢，这是一直存在于地核中的物质。

See, the team coated their diamonds in aluminum oxide to keep them from breaking, and it’s possible that the shiny stuff they saw was metallic aluminum oxide, not metallic hydrogen.

看，该团队在他们的钻石上涂上氧化铝以防止它们破裂， 他们看到的闪亮物质可能是金属氧化铝， 而不是金属氢。

In a paper published last week in the journal Science, two researchers from Harvard University announced that they’ve done what physicists have been trying to do for 80 years: they’ve created solid metallic hydrogen.

在上周发表在《科学》杂志上的一篇论文中，哈佛大学的两名研究人员宣布， 他们已经完成了物理学家80年来一直试图做的情：他们创造了固金属氢。

And if we could figure out how to make this stuff, it would be incredibly useful: It’s thought that metallic hydrogen would be a superconductor at room temperature, meaning that it would be perfectly conduct electricity.

如果我们能弄清楚如何制造这种东西，那将非常有用：人们认为金属氢在室温下是超导， 这意味着它可以完美导电。

And with it’s super-strong bonds, solid metallic hydrogen would also be a great way to store energy, which would make it a better rocket fuel than the fuels we use now, like liquid hydrogen and oxygen.

凭借其超强的键合力，固态金属氢也将成为储存能量的好方法， 这将使其成为比我们现在使用的燃料（如液态氢和液态氧）更好的火箭燃料。
