That was the big idea

Ben was satisfied with that answer and kind of likes the idea that infinity is big enough to be both odd and even.

本对答案很满意，他有些偏爱这样的想法：无穷大很大，大到既是奇数也是偶数。

The idea of dark energy was dreamed up ten years ago, to explain why the expansion of the universe that began with the Big Bang seems to be accelerating, rather than slowing down.

暗能的概念是十年前创造出来的，为了解释为什么宇宙的扩张自大爆炸开始后是加速的，而不是慢下来。

PERHAPS the biggest big idea to gather speed during the last millennium was that we humans might govern ourselves.

也许在上一千年，逐渐加速的一个最大的大胆想法是，我们人类能够管理自己。
