Insignificant? If you stand in a darkened corner of the world and look up, what is visible to your naked eye? Do you noticed the mottled, dark coloration in that vast space overhead? Perhaps a few streaks of lavender or rosy orange in the western sky hinting at a vanishing phenomenon only moments before? Can you discern the difference in size among the multitude of sparkling points that seem cold and offer little light; points that catch you barely breathing as your imagination stretches with wonder? Have you ever counted the clusters or given them names, or watched gaseous clouds slowly envelop and swallow them from view?
Do you ever visit the Astronomy Picture of the Day on the internet, to sound out odd names, like Cassiopeia, Trifid Nebula, Sag A, and marvel in the colors, or the distances, or the dust that floats across the frame from a explosion of energy a billion years as light travels toward your single moment in time? Does your mouth water for chocolate when you think Milky Way?Have you had galactic thoughts and cosmic questions, wondering what is out there beyond what you can see or sense or imagine? Have you seen comets arching across that vast darkness, sparkling tails of stardust marking their trail until you lose them from view?
Have you marveled at the distance, the vastness, the silence of the unknown with unknown questions as you looked at the frail, tiny creature that is you, dreaming? Have you wondered at your place, at your size in that miracle, one tiny iota of life in a universe that has no boundaries? Is there someone almost like you out there on a star so distant it's never been seen asking the same questions and wondering about you? Don't you hope so?
Do you think about the span of a single human life when measured against the billions upon billions of years displayed overhead; a full life that is no more than one grain of stardust when measured against celestial time you can never understand? Can you feel your insignificance amid the unreachable vastness? Can you laugh at how seriously you take yourself? Do you wonder why you would get angry that an overworked waitress brought you broccoli at dinner instead of peas? Do you see the absurdity of worrying about the mundane of tomorrow or if your team won the ball game, or you'll get the promotion, or if you should buy or lease a new car?
If you're honest, you know your total existence is a single moment, a brief blink of light on a horizon you cannot encompass. Humans and their teeny petty problems are as inconsequential, insignificant, and invisible within the totality of the universe as a wart on the nose of a gnat.
