We call these giant molecular clouds, because why not.

我们称这些为巨大的分子云，因为为什么不这么叫呢。

It's a huge molecule that causes a lot of pressure inside concrete. And starts degradation of concrete.

“氢是一种巨大的分子，会在混凝内部形成很多压力，使混凝劣。”

And they are extremely potent ones, causing thousands of times more warming per molecule than carbon dioxide does.

它们破坏力巨大，每分子所产生的热量碳要高几千倍。

The initial wave, the jam, may be started by some sort of disturbance in the disk, perhaps an overdense region created when a couple of giant molecular clouds smash together.

最初的波，也就是阻塞，可能是由磁盘中的某种扰动引起的，可能是一对巨大的分子云相撞时产生的一个密度过高的区域。

But at such high speeds the water molecules are forced to move too much, too quickly, and encounter massive resistance from every other water molecule it pushes against.

但是在如此高的速度下， 水分子被迫移动得太多、太快，并且遇到它所推动的所有其他水分子的巨大阻力。
