只有在平坦的宇宙中，空间才符合标准的几何规律——三角形的内角和精确地等于180度，平行线永远不相交。

Only in a flat universe does space obey all the standard geometry-class rules-the angles of a triangle add up to exactly 180 degrees and parallel lines never meet.

我知道自己输了，我知道俩条平行线是永远不可能相交的。

I know I lose, I know that two parallel lines will never be the intersection.
