Dark Matter.

It's hard to look up at the stars and think about the universe...
Think of an infinite amount of planets in an infinite about of galaxies, in a space that.. never ends, and never begins.
Maybe its easier to think about the sidewalks, or the trees, or ourselves for that matter... matter...
Matter is interesting isn't it? something that can never be destroyed.. only changed.
which means, our atoms, matter, and everything that makes us.. the singing birds, winding sidewalks, our chemistry homework!!
It all comes from those stars.  It all comes from out there..
"When most people look up at the night sky they feel small because the universe is so big... but I don't!  Because I know that my atoms came from those stars."

We may live in the universe... but more than that.. the universe lives in all of us..
