The map is relative to one location. You don’t want to see « rocks » and « rocks » for any distance smaller than 6000km, you want to see everyday objects. So you want the origin to be on earth surface
I got one of these printed by a banner-printing service who could do prints two metres tall and 60 cm wide or something. It came back with the bottom third blank - there are so many objects in the postscript file, it crashed their rasteriser. This was a cheap service, so they didn't check it before printing it out.
I rasterised it in software, and sent them the image, and that was fine.
I wonder how the distances to the solar system objects were chosen? If it was the average distance from earth, shouldn't sun be closest? I guess it is maybe the shortest possible distance?
The early universe's expansion was not accelerating, as the early universe was not dominated by dark energy. I don't know off the top of my head exactly when that changed, but z=0.76 seems about right. So I'm pretty sure that is what that is.
The reason the dominant form of matter changes is fairly simple. As the universe expands, the amount of matter doesn't change, so the matter density goes as 1/r^3. The amount or radiation goes as 1/r^4 as there is an extra loss of energy due to redshifting (E = hc/wavelength). Dark energy though is (we think) a constant, so as the universe expands, the amount of it stays constant.

Skimming the paper it looks like it was the positions in Aug 2003
Also what's the gap between the blue bits?
