那按照楼主的意思是,这个类星体是恒久不变的啦???百亿年还是一样滴??他是死体??? 我还是觉得您是逻辑含义理解错了,当然,仅是一家之言,我还是翻译成:因为光的传播速度,我们现在看到quasars是几百万年前的quasars,那时候它们正在经历宇宙的形成。。。。而不是:因为光的传播速度,我们现在看到quasars是几百万年前的quasars,正如它们正在经历宇宙的形成的一样 找了个native guy回答,就是说:The point here is that we need to make sure that we are talking about seeing the quasars as the quasars were at that time, NOT seeing the quasars in the way that people back then saw them. Some people might choose D; this answer means that we were alive then, and we are alive now; the quasars look the same to us both then and now. -- by 会员 sisichen666 (2012/11/10 17:11:35)
