Nothingness

Nothingness.
We encounter the word "Nothing" all the time, but we never really stop to consider it.
It's hard to define nothingness.  It could be what's running through my head as I type this blog right now.  Nothingness is typically thought of as the absence of everything.  Isn't it ironic (or is it, hipsters?) that pondering nothing can lead to more thoughts than when one ponders a matter in their daily lives?
Nothing in the sense of cosmology is really many things.  Take the vacuum of space for instance.  Is it truly nothing?  No, it's the amalgam of background radiation from a primordial time and tiny particles (the specifics of which are confusing and daunting to say the least).  So is nothingness really the absence of matter?

Without getting too scientific in this matter, let's consider that nothingness can be subjective.  It can hinge on each individual's definitions.  It can depend on the individual's past experiences;  their desires, goals, maybe even the food they had that day.  I think we can all agree to disagree on a firm definition.  The fact that nothingness applies to many fields of study (both in academia and in the lonesome midnight internet-surfer) leads to disagreement.  Sure, Webster's won't hesitate to slap a meaning on there, but who uses a dictionary anymore anyways?
Sure, having a firm definition is useful, but does it matter in life?  Will you be judged on your ability to define a single, ambiguous word?  I'd wager a guess on "probably not."  Did I just prove this entire post useless?  Maybe.

Just my two cents.
