In Big Bang theory, the state of the Universe is a singularity in early times, meaning that the Universe was once infinitely small.
在大爆炸理论里，早期宇宙的状态是一个奇点，这意味着宇宙曾经是无穷小的。
However, Eddington's revised theory requires a minimum length of space-time at early times, which means that the Universe could not have been a singularity.
然而，修正后的Eddington理论要求早期时空的尺度应该具有某个最小值，这意味着那时的宇宙不可能是一个奇点。
With Roger Penrose I showed that if Einstein's general theory of relativity is correct, there would be a singularity, a point of infinite density and space-time curvature, where time has a beginning.
Roger Penrose 和我曾表明，如果爱因斯坦的一般相对论是正确的，那就会有一个特例，在无限密集和空间时间弯曲这一点上，时间就会有一个开端。
