Great post. A question which doesn't have much to do with the main point - don't his calculations result in a plane with 2d co-ordinates rather than three dimensional? ie. with our galaxy, wouldn't you have to include the thickness to get any co-ord: (100 000 light years) * (12000 ly) / (2^128) = 3.336e^-17
