据预测21世纪科学将出现五大突破。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澎张。这就是说宇宙一定是在过去的某一特定时候开始形成的。 It is predicted that there will be five major breakthroughs in the science of the 21st century. We will know where we come from. Why does the Universe exist? Put another way, why is there a substance rather than nothing? Since the 1920s, scientists have learned that the universe is arrogant. This means that the universe must have formed at a specific moment in the past.
