Postcard 5

The first rule of orbits is
Never question the center
Do not doubt the validity
Of that around which you spin
Have faith that your planet
Has mass and will continue to
Exert a gravitational pull
You must not stop believing
There is a there there
For it is that which keeps
You moving through space
What you hold in your head
Will guide you even if the
Laws of physics and
Time-Space Continuum
Let you down
