Michelson and Morley had an idea to see if swift blew the wind
and crossed their beams (don't cross the beams!) into a half silvered mirror
so that if was slower than the other
we could see the beam arrive a little later

They both arrived at the same time

I was there to hear them when they did, watch their planes land and walk to baggage claim
I didn't have anything to say to them
They were here to disprove
to declaim

As is often the case
A single inconvenient truth
undoes the most beautiful theory

But they were family
And I was glad to see them just the same
