Maybe Space joined the World in the fun of "screwing with this asshole annoying pastries", so now space screws with dimensional proportions just to screw with the yu's. How long until Time joins the fun?
And yukkuris in general don't make sense, same way for their related stuff.
So it's still all the same, World mess up with them even though it doesn't make sense, Space does the same, Time being a force of it's own and joining the fun at this point is just something easy to expect.
