We have used the universe as a metaphor for the internet. If I were to take that to as much an extreme as a non scientist can, I would say that you could relate the stars, planets, satellites, black holes, even galaxies to the many groupings of people, information, and blogs. But the structure, the internet as a thing, the wires, circuits, and waves, the hardware and software, must exist in that metaphor to fully capture the concept. To be fair, we have no way of counting the stars in our entire universe. So to be able to represent it visually, and to bring it to a level that we can better grasp, let us focus first at or galaxy, and than look to our visible sky.
