Permeable Densities

     In a recent class discussion, a student suggested that space is an absolute, and is a container for all things that exist. I then posed a question asking him why, just as there is room in a partially-filled box, there were no empty pockets of space with no matter in them, because zones of vacuum do not exist naturally. One could counter with an argument that when we move to microscopic subatomic levels of matter, there seem to be empty pockets of space between the molecules and atoms. Only now, the space is held within the matter, not matter held within the space, which acts as a container! What if there is no empty space, only contiguous matter in which space is entrapped! Space, then, would always be contained by 'vessels' of matter, varying in density, which are contiguous. What if, like a precious and vulnerable child, space is always contained and held within matter! Contiguous containers of matter, containing space! Now, what would this world of permeable densities mean to the modeling of energy transfer?
