Progressively, larger objects substantially increase the timescale for collapse over still longer wavelengths.

进而言之，较大的天体，因要在更长的波长上坍缩，将大大增长时间尺度。

Colliding black holes, collapsing stars, and spinning compact celestial objects such as pulsars create ripples in the fabric of space and time that subtly distort the world around us.

黑洞碰撞、星坍缩以及自旋脉冲星所激起的时空结构波动，微妙的扭曲了我们周围的世界。

A burnedout star could collapse to so small a radius as to make the effects of general relativity quite important near its surface.

一个燃烧完的星球可能坍缩到如此之小的半径，以致在其表面附近，广义相对论效应相当重要。

Instead, they would collapse to form galaxies and stars, starting from about two billion years after the Big Bang.

然后反过来，坍缩而形成诸星系及恒星，这种情况开始于大爆炸之后约20亿年。
