The mounds represent the Milky Way and Andromeda. There is also a third circle that represents a supercluster of galaxies and another that is a multiverse that our own universe is likely to be part of. The roads surround it, joining the different "galactic" mounds in a black hole on the summits.
A ring of spiral rocks represents the multiverse, with more than 100 boulders. Each stone represents a different universe and consequently has different laws of physics.
A spectacular transformation for a space totally degraded by the hand of man.
