开始于1995年左右的第二次弦革命，使我们对宇宙的看法发生了巨大的变化，也许比1984年的第一次弦革命更甚。也就是说，将10维弦理论扩展到11维M理论，比最初将4维量子力学和相对论扩展到10维弦理论，具有更深远的意义。在简要回顾M理论之后，我讨论了大额外维的一些含义。然后，我考虑天文证据，并限制，大型紧致化的尺寸。我的结论与可能的解决方案之间的明显不一致的MSSM规模和字符串规模在弱耦合限制。2002年10月在得克萨斯州休斯顿举行的空间研委会2002年会议上发表的演讲。
The second string revolution, which begin around 1995, has led to a drastic alteration in our perception of the universe, perhaps even more so then did the first string revolution of 1984. That is, extending 10-dimensional string theory to 11-dimensional M-theory has had more profound implications than did the original extension of 4-dimensional quantum mechanics and relativity to 10-dimensional string theory. After a brief review of M-theory, I discuss some implications of large extra dimensions. I then consider astronomical evidence for, and constraints on, large compactified dimensions. I conclude with a possible resolution to the apparent inconsistency between the MSSM scale and string scale in the weak coupling limit. Talk presented at COSPAR '02, Houston, Texas, October 2002.
