So, now we have a new earth with much higher gravity.

所以，现在我们有了一个重力更高的新地球。

When the spaceship was lifting off, I could really feel the high gravity, said Yang Liwei.

“当飞船上升时，我能实在地感受到沉重的地心引力。”

The planet then got a few more hits because it is a bigger target and has higher gravity.

地球随后被击中了几次，因为它体积大，引力也大。

When the second satellite passes over that high gravity spot, it also speeds up and closes the distance.

当第二个卫星经过时，它也移动更快，拉回本来的距离。

Very high gravity is going to be a big issue.

非常高的引力将是一个大问题。

As the first satellite passes over a spot with higher gravity, its orbit speeds up and the two satellites pull apart.

当第一个卫星经过一个重力比较大的地方，它的轨道会被加速然后两个卫星距离被拉开。

So, it's truly fundamental, because earth gravity is quite deep. Earth has a fairly high gravity.

所以，它真的很重要，因为地球引力非常深。地球具有相当高的引力。

This on a night that I had originally designated for solving the space time geometry in higher spin gravity and building my Lego Death Star.

本来那天晚上 我是计划好要解决 更高自旋引力场下的时空几何问题 以及搭乐高死星的呢。

They re special  because they are so dense, so when you get close in to them you experience a way higher  gravity than you could get anywhere else.

它们之所以特别， 是因为它们非常密集，所以当你靠近它们时， 你会体验到比其他任何地方都高得多的重力。
