I found a crack in the sky

I found a crack in the sky At midnight, I looked up And as usual There was stars decorating The dark blue sea above But I caught it I saw a thin line, just north of the moon And as I concentrated, I could see what was beyond I saw the galaxy The stars, the planets And realized there were more than eight And I swore I saw a human Waving at me From one of the unseen planets Up above I saw more than our solar system I saw the universe In its entirety Its vastness was enough to crush me Making me realize How insignificant I really was Blue, red, orange, and colors I couldn't identify I spotted them in streaks across the cosmos Then suddenly I remembered I was still on earth And glanced at the earth's sky It was turning into dawn With pink clouds introducing the sun I tried to look back at the crack But it had closed up
