It's just that the finite speed of light distorts what you see.

只是有限的光速歪曲了你看到的东西。

Its age, and the finite speed of light, means no astronomer can look beyond a distance of 13.7 billion light-years.

它的年龄及有限的光速意味着没有天文学家能超越137亿光年。

Its age, and the finite speed of light, means no astronomer can look beyond a distance of 13.7 billion light-years. But it is probably bigger than that.

由于光速的限制和宇宙的年龄，这意味着天文学家看不到137亿光年以外的东西，但宇宙本身很可能更大。

ECONOMIST: In praise of astronomy, the most revolutionary of sciences

But those are also the farthest and faintest (because the finite speed of light means that to see objects when they were young means looking at things billions of light years away).

ECONOMIST: The truth is out there. Maybe
