The universe's purpose

 I don't think the universe has a purpose. It just is as a result of natural processes; we just are for the same reason.

I look at all the "wasted" space in the universe -- not just the vast distances in space, but the immense void that is the typical atom, and another that is the typical nucleus (if the nucleus were the size of the solar system, the "particles" in it would be no bigger than a few asteroids, if even that (they may be dimensionless points). Why does the universe waste all that space? It doesn't need a "reason" for what it does, it just does what it does.

If we need purpose in our lives, we have to provide it. This I think we can do without going too deep (go too deep and you defeat yourself).
