We'll know where we came from. Why does the universe exist? To put it another way, why is there something instead of nothing? Since the 1920s, scientists have known the universe is expanding, which means it must have started at a definite time in the past. They even have developed theories that give a detailed picture of the evolution of the universe from the time it was a fraction of a second old to the present. Over the next couple of decades, these theories will be refined by data from extraordinary powerful new telescope. We will have a better understanding of how matter behaves at the unfathomably high temperatures and pressures of the early universe.

我们将知道我们从哪里来。为什么宇宙会存在？换一种说法，为什么会有物质存在而不是空无一物？自20世纪20年代以来，科学家已经了解到宇宙正在扩张。这就是说宇宙一定是在过去的某一特定时候开始形成的。科学家们甚至已经提出种种理论，详尽地描绘宇宙从它形成的最初一瞬间一直到现在的演变过程。在未来的几十年中，由功能异常强大的新型望远镜所带来的数据将会使这些理论更加精确。同时，我们将进一步了解物质在宇宙初期不可思议的高温高压下，是如何表现的。
