Eleven-year-olds, they're all sitting in a little semi-circle looking up at me with big eyes, and I started, there was a white board behind me, and I started off by writing a one with 22 zeroes after it, and I said, "All right, now look, this is the number of stars in the visible universe, and this number is so big there's not even a name for it."
这群11岁的孩子们坐在一起围成一个半圆 睁大眼睛看着我，然后我就开始演讲 我身后以一张白板，我在上面 写下一个1和22个0，我说 “看吧，这就是我们能在宇宙里看见 的星星数量，这个数字太大了 我们都不知道怎样表达它。”
