But what are those ideas?

この宇宙の最大の疑問についてであることは知っていますが、

What's at the centre of a black hole?

それはどういったものなのでしょうか？

Black holes are incredibly dense objects with such strong gravity that nothing, not even light, can escape their pull.

ブラックホールは極度の密集物で

Hawking worked with physicist Roger Penrose to show that if you were able to travel to the centre of a black hole, you'd find something called a 'singularity'.

引力が非常に強いため、何も、そして

In a singularity, so much matter is squashed into such a small space that the force of gravity becomes infinite.

光でさえも、その引力から逃れることはできない。

Everything is crushed into a point of infinite density, punching a hole through the fabric of the universe, and tearing up the rulebook of physics as we know it.

ホーキングは物理学者ロジャー・ペンローズと共同研究をしており、

It's pretty frightening stuff.

ブラックホールの中心へ行けるとすると

What happens at the edge of a black hole?

「特異点」と呼ばれるものを見つけることができるという研究をしていた。

You might think that a vacuum is empty.

この「特異点」では多くの物が非常に小さい空間に押しつぶされるため、

But it's not. At least, not according to quantum theory.

引力の力が無限になり、

It's fizzing with particles and anti-particles that pop into existence from nowhere and then disappear.

全てが密度が無限大である点へと押しつぶされ

When this happens at the edge of a black hole, one of the pair of particles can fall in, leaving the other to escape.

宇宙の空間に穴をあけ、

This tiny stream of escaping particles is known as, ''Hawking radiation.''

我々の知っている物理の法則をズタズタに裂く

Now, those particles that fell into the black hole, they have a negative mass, and cause the black hole to get smaller, and smaller, until it disappears.

おそろしいですね。

It will take a while, in fact a very long while, but in its final moments a black hole will explode with the energy of a million nuclear bombs – leaving nothing behind.

ブラックホールの端では何が起きているのでしょうか？

So why is Stephen Hawking our most famous living scientist?

真空とはカラと思いでしょうが、

Well, he showed that at one point everything in our universe was squeezed into a singularity, which then exploded into the Big Bang, eventually forming galaxies, stars, planets, you, me, and everything in existence!

違うのです、少なくとも量子論によると。

That was the beginning of our universe.

それは粒子、反粒子といった

And I suppose the incredible thing is that he came up with all these profound, provocative insights without the convenience of being able to write anything down.

どこからともなく現れ

He did it all by thought alone.

消えるもので溢れている。
