We are part of the tremendous through
Forever surging in transcendent flight,
Perilous though the journey be long.
And all, it is ordained, will earn the right
To add our separate voices to the song
Rising triumphant from the chorus of the light.
What do we call visible light? We call it color. But the electromagnetic spectrum runs to zero in one direction and infinity in the other, so really, children, mathematically, all of light is invisible.
