时空曲率

我们得有非常大的质量或者很高的质量密度，才能产生很大的时空曲率。

It takes a very large mass or a great concentration of mass to produce much spacetime curvature .

时空曲率使地球得以保持在绕日轨道中，也驱使遥远的星系彼此更加分离。

The curvature of spacetime keeps the earth in its orbit around the sun and drives distant galaxies ever farther apart .

但时空曲率确实造成的现象，我们可以观察到，与最好的望远镜，在地球上，自然与夏普有远见的哈勃望远镜。

But the curvature of space does create phenomena that we can observe with the best telescopes on Earth , and naturally with the sharp-sighted Hubble .

但是如果时空的曲率很大，重力的量子效应就不可忽视。

When the curvature of spacetime is very large , however , the quantum aspects of gravity become significant .

弦论学家预期，当我们把宇宙的历史倒带，就会看到时空的曲率开始增加。

String theorists expect that when one plays the history of the universe backward in time , the curvature of spacetime starts to increase .

当物质在太空中加速运行时，它会改变时空结构的曲率。

When matter accelerates through space , it changes the curvature of spacetime .

当时空结构的曲率发生变化的时候就会产生引力波。

Gravitational waves are produced when there is a change in the curvature of spacetime .

广义相对论将重力归因于时空连续体的曲率，而这与量子理论的框架格格不入。

Gravity , which general relativity attributes to the curvature of the spacetime continuum , stubbornly resists being incorporated into a quantum framework .
