think of it as a city..... it will continue to expand to the outer regions of the city.... but the inner city, say the streets, or the buildings... they do not expand... they stay the same size... just like the atoms in the Universe... they stay the same size while our Universe expands into a "void" if i may call it that, that we didn't yet call it our Universe that it expands into. i hope i made the comprehendible to something you can relate too!!!!

lol the sky isnt blue.... bottom line. we just see it that way... our eyes basically trick us.... there is nothing above us that is matter that is blue. it all has to do with our atmosphere tricking us.
