Universe(宇宙)

               Universe

      Where do we come from? How did the universe begin?Why is the universe the way it is? How will it end?

     All my life, I have been fascinated by the big questions that face us, and have tried to find scientific answers to them.If, like me, you have looked at the stars, and tried to make sense of what you see, you too have started to wonder what makes the universe exist. The questions are clear, and deceptively simple. But the answers have always seemed well beyond our reach. Until nOW.

      The ideas which had grown over two thousand years of observation have had to be radically re-

vised. In less than a hundred years, we have found a new way to think of ourselves. From sitting at the center of the universe, we now find ourselves orbiting an average-sized sun, which is just one of millions of stars in our own Milky Way galaxy. And our galaxy itself is just one of billions of galaxies, in a universe that is infinite and expanding. But this is far from the end of a long history of inquiry.Huge questions remain to be answered, before we can hope to have a complete picture of the universe we live in.

      I want you to share my excitement at the discoveries,past and present, which have revolutionized the way we think. From the Big Bang to black holes, from dark matter to a possible Big Crunch, our image of the universe today is full of strange sounding ideas, and remarkable truths. The story of how we arrived at this picture is the story of learning to understand what we see.

  宇宙

    我們來自何方?宇宙如何開始?為什么宇宙是這樣的?它將如何結(jié)束?

    我一生都迷戀于我們所面臨的這些大問題并試圖找到他們科學(xué)的答案。如果你曾像我一樣觀察過星星，想了解你看見的東西，你也已經(jīng)對宇宙的起源產(chǎn)生了好奇。這些問題很清楚，其簡單卻是假象。問題的答案總是遙不可及。直到現(xiàn)在。

    過去兩千多年的觀察所孕育出來的觀點(diǎn)不得不更改一新。在不到一百年的時(shí)間里，我們找到了審視我們自己的新方法。過去我們自認(rèn)為是宇宙的中心，現(xiàn)
