Where do we e 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 plete 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
我们来自何方?宇宙如何开始?为什么宇宙是这样的?它将如何结束?
我一生都迷恋于我们所面临的这些大问题并试图找到他们科学的答案.如果你曾像我一样观察过星星,想了解你看见的东西,你也已经对宇宙的起源产生了好奇.这些问题很清楚,其简单却是假象.问题的答案总是遥不可及.直到现在.
过去两千多年的观察所孕育出来的观点不得不更改一新.在不到一百年的时间里,我们找到了审视我们自己的新方法.过去我们自认为是宇宙的中心,现在发觉我们围绕一颗体积中等的太阳在转,而太阳只是银河系中数百万颗恒星中的一颗.而我们的星系又只是数百万个星系中的一个,存在于无穷无尽、不断扩展的宇宙中.但这远没有解决我们长久以来的疑问.很多重大问题尚未得到解决,更别说要完全了解我们生活的宇宙的全貌.
我希望你能分享我对过去及现在的发现的兴奋之情,因为这些发现改变了我们的思考方式.从创世大爆炸到黑洞,从黑色物质到可能出现的大坍缩,我们今天的宇宙观充满前所未知的观点和引人注目的真知灼见.我们形成这样的宇宙观的过程也就是我们学会理解耳闻目睹的一切的过程.,11,
Universe
Where do we come from? This is still unknown. But we know that we live in a universe full of infinitely wonderful scenes and stars. The beginning of the universe was the Big Bang, approximately 13.8 billion years ago. We are still trying to understand the essence of mysterious substances such as black matter and black holes.
Why is the universe like this? This is also a mystery. The universe seems to be filled with some order or wisdom, and we are still striving to understand the laws behind everything and how the universe was created.
What is the end of the universe? Based on existing research, we already know that the universe is accelerating its expansion, but we are still unsure how it will end, whether it will collapse or expand permanently.
Our exploration has only just begun, but we have already made some amazing discoveries. The new technologies adopted by scientists help us better understand the world around us, and these new technologies have shared many deeper truths about the universe and our lives with us. The universe is a complex and wonderful ecosystem, and with every step we take forward, we can open a more mysterious door and showcase more infinite possibilities.
宇宙
我们来自何方？ 这仍然是未知的。但我们知道，我们生活在一个宇宙中，宇宙充满无限奇妙的景象和恒星。宇宙的开始是宇宙大爆炸，距今已有约138亿年。我们还在尝试理解黑色物质和黑洞等神秘物质的本质。
为什么宇宙是这样的？ 这也是个谜。宇宙似乎充满某种秩序或智慧，我们还在努力理解一切背后的规律，以及宇宙是如何被创造出来的。宇宙的终点又是什么？根据现有的研究，我们已经知道，宇宙正在加速膨胀，但我们仍不确定它将以何种方式结束，大坍缩还是永久膨胀。

我们的探索才刚刚开始，但我们已经获得了一些惊人的发现。科学家们采用的新技术帮助我们更好地理解我们周围的世界，而这些新技术已经和我们分享了很多关于宇宙及我们生活的更深层次的真相。 宇宙是一个复杂而奇妙的生态系统，我们每向前迈进一步，就能开启一扇更加神秘的大门，并展现更多的无限可能。
