These three prejudices led Einstein to introduce the cosmological term to construct a static solution that was finite and yet had no boundaries—his universe curved back on itself like the surface of a balloon [see illustration on page 74].

这三项偏见使得爱因斯坦引入了宇宙项来建构一个静态解，这个静态宇宙解是有限的也是没有边界的──它会弯曲回来，像是气球表面。
