Because of the reduced gravity, new forms of more efficient travel could be developed.

由于重力降低，可以开发出新的更高效的旅行方式。

In reduced gravity, these fluids move freely in our bodies, creating a similar feeling to a head cold or blocked sinuses and leaving many foods tasting bland.

在重力降低的情况下， 这些液体在我们体内自由流动，产生类似于头感冒或鼻窦阻塞的感觉， 并使许多食物尝起来无味。

But the reduced gravity on the Moon makes them hundreds of times bigger, creating colossal cave systems that are up to a kilometre across and hundreds of kilometres long.

但是月球上重力的减弱使它们变得大了数百倍，形成了长达一公里、长达数百公里的巨大洞穴系统。
