I've never stipulated that space was any sort of void. At 0.1'c'
you'd have to avoid coming in contact with a common dust bunny.

The Alcubierre Drive and "Surfing a Warp Bubble" looks interesting.

But still, until we can safely utilize antimatter, a good enough ion
propulsion drive should be capable of giving us 0.1'c'.
