I know space is infinite beacause I can drop a penny on my floor through space. The penny was contained by the floor, but when I drill a hole in my floor and drop the penny again it continues into more space. We look at the space under our house as being confined. We call it a crawl space suggesting all our lives that the space is confined by the house. Thats not the fact. The fact is that our house is contained in space. The crawl space is not contained by the house the house is contained in space. Again its hard to explain without some new words.
