Pi

2.7 trillion digits and still counting
Some mysteries are not hidden
They are just never ending

No pattern to be found
The only one found
Easy as pie

Depends how detailed you want to be
We do not care to know things well
Enough has taken us far

The farthest thing we have ever thrown is still going
We wonder the mountains of other planets
Navigation data says a mountain built by wind

We can explain Mars much better than Earth
We often crash into it
