A vast expanse of nothing

Nothingness.  Void.  Empty space (woah).  It's a weird concept.  Why do you need to have something to represent nothing? 

I guess you could just refer to it the measure of distance between two bits of something.  Much of that distance simply doesn't have anything in it.  It's place-holder distance.  It's like a concession to our sense of perspective.

Or maybe it's more than that.  Maybe it's potential existence.  A very real reminder of potential in a universe where so little actually lives up to its potential.  Maybe empty space is a call to action.  Maybe it's a challenge slapping us in the face with a glove packed with lead shot to get off our collective asses and actually accomplish something.  Or maybe I'm just rambling, or filling space in a blog I decided to update daily.

Or, since this is something of a departure from everyday thought, maybe I'm just trying to live up to the the title 'far orbit of the mind.'
