Astronomers tell us quite wonderful things
Of stars, and of galaxies, Saturn's rings,
And though they are dealing with distances vast,
They manage to tell us of things that have passed.
It started, they say, with a “bang,” and when 'twas over
There was some debris left that they still can discover.
To probe the deep past they use stars' distant light,
And they assure us they manage to get the facts right.
For light's speed is great, but finite, as we know,
So they can analyze stars' feeble glow
And determine precisely what happened before,
Ten million years past, or perhaps even more.
I think what they tell us is most likely true,
Still, I hope astronomers know what they do...
