The realities, I think that AleSir meant the other worlds between which they were teleporting time and time again.

Aether can smash you with a signle touch, throw you away, in a way materialize (well, not as solid matter I think) and turn matter into darkmatter, the thign which Malekith tried to achieve. Thats probably what can be said to be observed of Aether's powers.
