"At the far end of a wormhole, two hundred light-years distant in real space, coherent photons begin to dance a story of human identity before the sensoria of those who watch." — Accelerando
One final possibility is that the expansion of the universe isn’t accelerating at all but merely looks that way to us.
In terms of special relativity, being able to travel faster than light is effectively equivalent to time travel—at least from the perspective of observers in different frames of reference. They see the light from your arrival, which is close to them, a long time before they see the light from your departure, which is a long way away. Because you're outrunning the speed of light, events appear to happen out of sequence.
