Dark energy need not be a fearful thing. Maybe things are accelerating
precisely because gravitational forces are less powerful over a greater distance,
as the universe expands. And it is mentionned herein: they end up moving faster
than the speed of light with respect to us ie we are moving in the opposite direction,
ourselves, from some of what we see...
As for the very distant future, there are projected limits to that, as well...
