As long as we walk this earth， one thing we should all discover is this. The more you know， the more you know you don’t know. That’s a quote1 from Aristotle， the Greek philosopher who lived over 2，300 years ago. It basically2 means that no matter how much we learn in school as kids and later in life as adults， we’ll find there’s always more to learn about everything.
只要我们走遍这个世界，我们都应该发现的一件事就是：你知道的越多，你就知道，你不知道的更多。这是2300多年前希腊哲学家亚里士多德的一句话。它的基本意思是，无论我们儿时在学校以及在成年后的生活中学到多少，我们都会发现总会有更多东西要学习。
If we decide that we know everything there is to know and stop being opening to learning， we become ignorant3 and miss out so much that our wonderful world has to teach us.
如果我们觉得已了解所有知识，并决定停止学习，那么我们就会变得无知，并错过如此之多，以至于我们精彩的世界不得不来教导我们。
As smart as Aristotle was， many things have been discovered in the hundreds of years since he lived. Many great philosophers and scientists have followed， and each one as built upon the knowledge of people who have gone before them.
像亚里士多德一样聪明的人们，在他之后的几百年以来已经发现了很多东西。许多伟大的哲学家和科学家都遵循了这一点，每一个都建立在他们前辈的肩膀之上。
■ The First Image of a Black Hole
■ 黑洞的第一张照片
Recently， the world’s greatest scientists of our day were finally able to create a real picture of a block hole. It was an amazing achievement and incredible4 discovery. It confirmed5 many theories about the existence6 of black holes and how they work. It also proved that Albert Einstein was right about his Theory of General Relativity on the relationship between space and time.
最近，当今世界上最伟大的科学家终于能够创造出一个真实的黑洞照片。这是一项了不起的成就，是一个难以置信的发现。它证实了许多关于黑洞存在及其运行方式的理论。这也证明了爱因斯坦关于空间与时间关系的广义相对论是正确的。
The image also proved that recent scientific calculations7 about black holes were correct. This discovery， however， is more than a story about the advancement8 of technology that allowed humans to see an actual black hole for the first time. It’s also a story of how many scientists from all over the world worked together for many years to achieve this great feat.
该图像还证明了最近关于黑洞的科学计算是正确的。然而，这一发现不仅仅是一个关于技术进步的故事，它让人类第一次看到了一个真正的黑洞。这也是一个关于世界各地有多少科学家共同努力才实现这一伟大壮举的故事。
For one， just to make the now famous black hole photograph took many observatories9 from all over the world working together to create one virtual10 telescope the size of our earth.
首先，为了制作现在这张著名的黑洞照片，来自世界各地的许多观测台共同造出了一个与地球大小相当的虚拟望远镜。
■ More Discoveries Yet to Come
■ 未来还有更多发现
While the first image of a real black hole confirms many theories that were calculated using mathematics， scientists are the first to point out that this great discovery is the beginning of many more discoveries yet to come.
雖然黑洞第一张真正的照片证实了许多使用数学计算的理论，科学家们首先指出，这一伟大的发现是未来更多发现的开始。
Producing the black hole image took over 200 scientists working together from all over the world. They all would be the first to tell you that as much as we know about the Universe， there is so much more we don’t know.
制作黑洞图片吸引了来自世界各地的200多名科学家。他们都会首先告诉你，尽管我们对宇宙知之甚多，但还有更多我们不知道的东西。
The lessons we learn from the first image of a black hole are many. One important lesson is to always keep learning. You never know what amazing discovery you will find.
我们从第一张黑洞照片中吸取的教训很多。一个重要的教训是始终坚持学习。你永远不知道你会有什么惊人的发现。
