Poem: Orbit

I just read Inkshell's post comparing science and poetry, and thought I would repost a poem from my old blog that uses scientific concepts for its imagery.  I seem to do this from time to time, being both a scientist and a writer (amateur on both counts).  Science speaks to me, and it makes me think of things in ways I hadn't thought of them before, which is practically a definition of poetry.

Orbit

There is a certain distance from a black hole,
They say,
Where light is bent in a perfect circle,
Each ray
Orbiting the singularity forever.

In that orbit,
A ring could be built
In which you could walk
In a seemingly straight line
But always end up back where you started.

But, of course, we can do that here
On solid ground
Without any of that
Messy space travel
And time dilation.

But ending up in the same place you started
Isn't always so bad.
Write a bit on the wall,
And you can learn something new
Each circuit of the journey.
