A comment on Project Hyperion: Interstellar ship design competition. Parent comment
Up to 0.1c is from the interstellar spaceship competition "cruise" speeds (also used 0.01c) as presented in their deck.
They're a few orders of magnitude difference.
Also, there's plenty of resources around on interstellar travel that shows interstellar dust/debris is going to be a huge problem.
For example Atomic Rockets, which has a bunch of good reference materials (albeit poorly organized), or the Astronomy Cafe
