Distance is a function of time. All things, in a cosmological sense (according to Sir Hawking ), are moving away from each other. As such, the more time that elapses, the greater the distances between each. But, time can get distorted, as we know. Think visually. Imagine a one cubic inch of jello, any flavor will do. Now imagine two poppy seeds, somehow imbedded in the cube. Over time, the measurable distance between the seeds will change. Perhaps one seed is minutely more massive than the other so it "sinks" faster than the other (because the resistance of the jello holds the lesser massive seed stationary longer). Now, here's the part where you go "Huh?" Imagine the jello being "time". The movement of the poppy seeds, pushes the jello and compresses it, like a shock wave preceding a bullet, while the jello behind the seed decompresses forcing the jello to fill the vacuum which follows the seed (as in the cavitation of a prop on a boat). The jello is "distorted" by the movement of the seeds, just as time is distorted relative to the speed of an object as it approaches the speed of light.

Or, think even more visually, by turning the channel and watching something with Jennifer Aniston in it.
