What's the size of our experience? How big is our world? How big is the universe we observe. From the eyes of a child, sometimes I ask myself innocent questions about where we are in this universe. I read somewhere that if the Universe was a beach, earth would be a grain of sand. The vastness of universe and dark space used to scare me as a kid, thinking there's nothing beyond my planet and it was almost a innocent claustrophobia within a planet (heh); Sometimes I think looking at earth from space and understanding our relative existence in the universe, suddenly all our problems, challenges, credit card bills and misery seems so irrelevant, localized to an insignificant magnitude.
