This small crystal sculpture represents just the portions of the universe we’ve been able to observe using data from the 2dF Galaxy Redshift Survey. Not only does this map give us a glimpse into our place in the vast reaches of space, but it also serves as a reminder of the challenges we still face in learning about the great beyond, as the further from Earth you go, the more difficult it becomes to locate galaxies that are bright enough to be seen. It holds an official Guinness World Record as the smallest-scale commercially available map, a distinction you can chalk up to the sheer incredibly great size of the universe as we know it.
