Light-years and stuff
Here I launch into astrophysics, but
Before I bring up billions and trillions
Of galaxies and light-years and stuff,
Let me just admit my ignorance
At the beginning, because it’s the beginning
That caught me, when they explained
About the new orbiting telescope soon to
Replace the Hubble, which will take
Pictures so far into deep space that—
Because it takes so long for the light
To get here from there, and the universe
Is thirteen billion years old—the images
Will represent what happened then.
