You can't for a number of reasons.


The image above is a NASA depiction of the universe as we know and see it today. However, astronomers agree that the actual shape of the universe is a sphere, a ball if you will. The entire universe exists on the surface of that ball. The problem is, no one knows where the various galaxies shown above belong on that ball rendering any depiction of the actual universe impossible.
