Hubble-scopes aloft will see anew;
Again, the centers of our souls will change.
Perhaps the things we most believe are true,
Ptolemy-like, will strike our sons as strange.
Years of light, long hidden by the air,
Millennia of thought will burst and scatter;
Overhead, the stars will still be there,
Though shifted from the poles that really matter.
How wonderful to know that what we know
Each mystery unravels from below,
Reveling in nights beyond the stars!
So let it be with every day:
Discoveries themselves always betray;
A fresh idea files older thoughts away,
Yet spins the ancient tales of life on Mars.
