Tip: If a frame has visible borders, the user can resize it by dragging the border.

如果一个框架有可视边框，那么用户可以通过拖曳边框来改变框架大小。

According to the theory of general relativity, the speed and angular momentum of such a large spinning body twists the space and time around it in a process called frame-dragging.

根据爱因斯坦的广义相对论，像银河系这样的巨大自旋物体的速率和角动量在一个称为框架牵引的过程中会扭曲周围的时空。

It was also found that, as our planet rotates, it drags space-time with it - a phenomenon known as frame-dragging.

同时也发现，地球旋转时会拖拽时空-所谓的参考系拖拽现象。

That may sound taxing to detect, but it is nothing compared with the precision required to measure frame-dragging.

This phenomenon is a spiral distortion of space which should if relativity is correct happen when massive bodies rotate. (In essence, such bodies drag space round with them.) Frame-dragging is predicted to cause an additional precession of one hundred-thousandth of a degree, perpendicular to that caused by the geodetic effect.
