In one Friedman model that is possible, in the other two it's not. That theory is based on the expansion and eventual contraction of the universe and is obviously impossible to test because you would have to travel for billions of years and most likely would have had to start billions of years ago anyway.
Sounds like someone's been listening to Modest Mouse.
