Across the Curtain: Reflections on the limits of human knowledge

Across the flimsy curtain of common "reality"
are spheres of existence we seldom conceive -

Spheres where atomic clocks move in nano-rhythms
& each breath seems an eternity

Dimensions in which galaxies last but a day
& all human knowledge becomes a nugatory flame

Realities in which a single snowflake
appears as an elegant spaceship

& others in which large planets
are fleeting, microscopic blips

Whenever people around you implore
"be realistic"
smile at them & reflect:

What do any of us know of reality?
Can we ken the depths?
