I kissed her good night and left the room.
Anyone else want to have a stab at a response to that?

Dennis your daughter is very clever... she may care to read the thread on nothing .... and she is so right there is indeed something..it is everything or rather a part of everything that there is and was flying in all directions from everywhere so that all those particles creat a universal push or pressure the source of all energy manifesting as all the forces via various interactions with matter or indeed itself .... yes there is something there..
As an exercise for the imagination consider a cube of the remotest space such that hubble could analyse all the light that reached that point... a hubble sitting within such a cube would determine there was not any point of the visable universe that did not bath that cube with billions of photons from every conceivable direction... imagine each photon is the size of a grain of sand and visualise how they would all fly hiterer and thither at the speed of ..er well light
AND there is no where you can go where the universe doth not deliver billions of photons from everywhere...I feel she must have grasped such
Encourage her by telling her what a wonderfully profound inteligence she has.
