One theory is that they are youngsters, giving off heat as they collapse inward due to the pull of their own gravity, but nobody knows for sure.
有一个说法是，它们还处于幼年，由于自己的重力所拉，在衰竭的同时发出热量，但没有人能肯定这种说法。

And this universal pull, this gravity, everywhere operates on the same math: the greater the masses of the bodies and the closer they are together, the stronger the pull.
这个宇宙拉动的力量，即重力，在任何地方都以同样的数学原理运作：质量越大，距离越近，引力越大。
The force of gravity starts to pull together huge regions of relatively dense cosmic gas, forming the vast, swirling collections of stars we call galaxies.

But gravity lessens with distance and this means that the pull from the Moon is stronger on the side of Earth that is facing the Moon.
但是，引力随距离增大而减小，这意味着月球施加在朝向自己那一面的地球部分的拉力要大些。
It's a gravity as strong as Manhattan's but the opposite kind-the beckoning of few roads and few people, the pull of a wild region large enough to have an "interior."
这种引力像曼哈顿岛的那么强烈，但是是另外的一种——稀少的道路和人烟，一个巨大的拥有“内部空间”的自然地区。
Gravity is the attraction, or pull, of one object on another object.
引力是一个物体对另一个物体所产生的吸引力，或拉力。
