I've got a questioon for ya...
What is space (outer) held in? What holds space?
If you think about it, everything is contained in something...molecules revolve around atoms...which make up objects, those objects are contained within something, say like cells to make up humans-to give one example. We humans are held here on earth. Earth is held within our solar system, which is held within our galaxy, which is held within "space." So, what is space held in? Probably too vast of a knowledge for us to understand...
