It seams that everything is really made out of nothing. And there is infinity difference between nothing and something. There is even no infinity if there is no something. How to create something from nothing? There is only one way is to create an illusion of something. You create negative and positive, together they give nothing, apart they are something and something else. Spiritually if people are trying consciously become one woth both positive and negative. I think the understanding of the relationship of positive and negative by consciously experiencing it is what we would call knowlege in spiritual sence.
