Cos all of the stars are fading away.

因为所有的星星正逐渐隐去.

Stars a bit further away move faster, because they are being pulled by all of the stars in between them and the center.

稍远的恒星运动速度快一些，因为它们受到了和中心之间所有星星的牵引。

For that brief moment in time, the glow was brighter than all the stars in all the galaxies in all of the known Universe. It was a very big bang.

在那短暂的一瞬间，碰撞产生的光芒令已知宇宙中所有星系中的所有恒星都黯然失色。那是一个名副其实的大爆炸。

Pictured above is a series of images digitally stacked so that all of the stars images coincide. Here, Mars appears to trace out a loop in the sky.

上面图是一系列数码照片叠加而成的，让恒星重合，而火星貌似在天空中画了一个环。
