why is it that galaxies are placed the way they are in our observable universe? as spirals of solar systems with empty space between them? isn't it a concept of the big bang theory that, the universe was created from a point of singularity? And at an instant, all matter was ejected from that point? if so, then why does our universe appear the way it does? Should it not look more like scattered planets and stars exploding from a single point? which then eventually collapse back to that point? to me it seams more reasonable that each galaxy is it's own, and not created relative to other galaxies. something like a big bang to create each galaxy.
