And eventually, that spinning generated so much force that it flattened the cloud into a disk shape.

最终，旋转产生的力如此之大， 以至于将云压扁成圆盘状。

He produced from under his arm the carefully cuddled-up package, which was in shape a round flat disk, like a dinner-plate, tied in paper.

他从胳膊下拿出一个小心翼翼地抱成一团的包裹，形状像一个圆盘，像餐盘，用纸扎着。

So over time, through collisions and crashes, the cloud loses its loft and flattens into a spinning, roughly 2 dimensional disk shape, like a solar system or a spiral galaxy.

所以，随着时间的推移，通过碰撞和崩解，星云失去了它垂直于旋转平面上的粒子高度变成扁平状（大概是二维的圆盘）旋转，就像太阳系或螺旋星系。
