curvature

Matter, energy and dark energy all produce curvature in space-time, however..而事实上，物质、能量和暗能量在时空中都会产生弯曲。

The hyperbolic surface, which has so-called negative curvature because its surface curves up and down at the same time, like a saddle, just might represent the shape of the universe..双曲表面，即通常所称的负曲率，因为它的表面曲线同时有的向上和有的向下，像一个马鞍，也许这样就可以代表宇宙的形状。

Then, with a few assumptions about the curvature and contents of the universe, they can reconstruct the positions of those objects from redshifts..然后，通过一些关于宇宙曲率和内容的假设，科学家们能够重建这些物体的位置。
