4周搞定2000+托福核心词
observable
常考释义
However, when we look at the 100 billion stars in our galaxy (the Milky Way), and 100 billion galaxies in the observable Universe, it seems inconceivable that at least one of these planets does not have a life form on it; in fact, the best educated guess we can make, using the little that we do know about the conditions for carbon-based life, leads us to estimate that perhaps one in 100,000 stars might have a life-bearing planet orbiting it.
然而，当我们观察银河系的1,000 亿颗恒星及宇宙中可探测到的1,000亿个星系的时候，我们很难相信这些恒星中没有任何生命体存在。事实上，凭借我们仅有的一点点对于碳基生命体的知识，我们可以做出的最有根据的推测就是：也许每十万个恒星中就会有一个可能孕育生命的行星围绕着它在运转。
