What is really interesting is the plan, the seeds of this galactic structure were present in the first millionths of billionths of a second from the creation event, the Big Bang. As the universe has unfolded from that original tiny dot "singularity", racing ever outwards at speeds possibly even greater than the speed of light as you approach the extreme "edges" over the last 15 billion years all the order, the clusters, the super clusters, all this structure, came to be just as it was programmed to be, from the very beginning!
All the atomic elements, all the laws of physics, chemistry, mathematics, all were present in that primordial fireball and conspired together to bring into being through stellar evolution and the interplay of the four fundamental forces of nature everything that is. It was the greatest display of overwhelming power, design, process, engineering, intelligence, creativity, thought, and purpose that can hardly be comprehended by our minds.
And the most neat thing about it? It all had to be, just as it is, for mankind to arrive on the scene 15 billion years after the event began. The entire purpose of this grand creation was one...for God to bring mankind into being, and for mankind to come into being without violating any natural law whatsoever. In that God orchestrated and shepherded this entire cosmos, and it had to be as big as it is, as old as it is, as grand as it is...every galaxy has a purpose, every atom has a purpose, to be part of the plan, the making of mankind so God could make a family, to make the physical home for incredibly complex life called man, so God could begin to make his family. All those clusters and super clusters, they all effect one another, they control the rate of expansion, they create long term stabilities and instabilities, depending on where, so that the process to make earth, to make the elements, to create a nice home on a rocky planet on a stable spiral arm with a great view of the cosmos yet protected by from the chaotic center of this galaxy...all that you see in that photo is what was necessary to be so that we can exist.
Science is starting to understand that yes the earth is the center of the universe...it is the point of the whole shebang!
