Nerd Thought

Thinking of outer space makes me realize that we define so much of life using ourselves and earth as a reference point. Doing so is certainly practical, and even necessary, but it's not so much true as it is convenient. Really, there is no true below or above. Only that which a planet’s gravity defines. Leave that planet, escape its gravity, and suddenly “underneath” doesn’t exist. Indeed, the vast majority of the universe does not recognize such terms. In outer space, position is relative.
