Well, it's dark energy that is accelerating the expansion, not dark matter. But one doesn't even have to talk about accelerating expansion to encounter the issue of very distant objects "moving" away at superluminal velocities. Plain old expansion alone will have this effect. The main point is, the objects are not moving through space at faster than light speed. It is the billions of lightyears of space in between that is expanding, and this all adds up to an apparent recessional velocity faster than light. Einstein says nothing can move faster than light, but his theories do NOT say that an accumulation of expanding space can add up to an apparent recessional velocity faster than light.
