Cosmic wormholes might open a doorway to the other side of the galaxy, but scientists continue to ponder the rich possibilities of another loophole in relativity: the warp drive.
宇宙虫洞也许能提供一种到达星系另一侧的途径，但科学家仍然在考虑另一种更靠谱的相对论漏洞：翘曲航行。

In relativity you'll find that whenever you have a choice among things that are equally possible, you are dealing with relative things.
按着相对论的说法你就会发现，每当你在众多同样可能的事物中需要选定一种解释时，你就是在跟相对的事物打交道。
In relativity, your observations must always be with respect to a particular observer-an observer with a well-defined motion relative to whatever is being observed.
在相对论里面，你的观察总是必须会涉及到一个特定的观察者-一个相对于被观察物有着明确的相对运动的观察者。
In relativity, your observations must always be with respect to a particular observer-an observer with a well-defined motion relative to whatever is being observed.
