I suspect XKCD is right, but I hope it is something like this.
This sort of shifting from our three spatial dimensions, into other mutually perpendicular dimensions, and then back into spatial dimensions in a different location, is the only way I can think of that interstellar travel would be viable on biological timescales.
Oh and apologies on the poor typing in my previous post, especially "neurinos".
