I call the universe "The Universe" because it is the culturally and socially accepted phonetic combination where I have grown up and currently reside to refer to the big picture. My attempts to refer to it as anything else usually gets odd looks.

But, yea. There are no objects, just one complex system. Space reverberates into knots we call light, light interacts with more light to create matter, matter combines with more matter to make molecules, molecules aggregate to form cells, cells come together to ultimately form brains, and then brains come together to form...
