Maybe a better idea would be to build a megastructure somewhere closer to the Solar System.

也许在离太阳系更近的地方建一个超级建筑更好。

Once this megastructure is finished, energy has become practically unlimited for molding the home system however they see fit.

一旦这个巨型结构建成，不论他们怎么看，可被用来改造他们的恒星系的能量几乎就是无限的了。

But when scientists looked, they didn't find remnants of harvested stars, decaying megastructures or scars of great interstellar wars.

但当科学家们仔细观测时，他们并没有发现被采集过的恒星、废弃的巨型结构或者史诗般的星际战争的痕迹。

Chicago is not the ideal place to build a megastructure like this one.

芝加哥不是建造这样一座巨型建筑的理想场所。

And one of the more interesting theories was that we were witnessing the construction of a giant alien megastructure called a Dyson sphere.

其中一个更有趣的猜测理论是，我们正见证着一个巨大的外星巨型结构的建造——戴森球。

For the inhabitants of the megastructure, it would always be daytime.

对于巨型建筑的居民来说， 它永远是白天。

Because the megastructure would turn out so enormous, it would break any known molecular bonds.

因为巨型结构会变得如此巨大，它会破坏任何已知的分子键。

Another innovative megastructure was proposed  in 1975 by a NASA Summer Study at Stanford University.

1975 年，NASA 在斯坦福大学开展的一项夏季研究提出了另一个创新的巨型结构。

In 2006, the Kalpana One Orbital Settlement  was proposed as an improvement upon the megastructures from the 1970s.

2006 年，卡尔帕纳一号轨道定居点被提议作为对 1970 年代巨型结构的改进。

They may have finished their first megastructures, and they might be in the process of moving staff between stars, transmitting enormous amounts of information into space, by accident, or on purpose.

它们可能已经建成了他们的第一批巨型结构，可能正处于在恒星之间运输物体，并无意或有意地向太空传输大量信息的过程中。
