This is nice too. in a sweet sad kind of way. Made me smile and think, both of which I like doing.

(btw: "pluto was taken from his thrown" should, I think, read "pluto was taken from his throne". I may be wrong)

I'm not sure if in the fist line you actually mean 'throne' rather than 'thrown'. If not, ignore me. Interesting though, how very... simple and definite you've made our Universe sound when Scientists have been trying and struggling to find out it's deepest secrets.
