All that we really need to plot out the future of our universe are a few good measurements. This does not mean that we can sit down today and outline the future course of the universe with anything like certainty. There are still too many things we do not know about the way the universe is put together. But we do know exactly what information we need to fill in our knowledge, and we have a pretty good idea of how to go about getting it.
Perhaps the best way to think of our present situation is to imagine a train coming into a switch yard(调车场). All of the switches are set before the train arrives, so that its path is completely determined. Some Switches we can see, others we cannot. There is no ambiguity (不明确) if we can see the setting of a switch; we can say with confidence that some possible futures will not materialize (实现) and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the tracks leading out, but we have no idea which one. The unseen switches are the true decision points in the future, and what happens when we arrive at them determines the en tire subsequent course of events.
When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.

解析
本文属于科技文章,但是作者没有使用过多的专业术语和专门概念,而是将宇宙的形成比喻为列车编组调车,进而指出科学研究的目的是减少不确定性进而获得可靠结果。由此可知,作者是为一般听众和读者所写的。
