Forks in the Road

Newton had his prism, and knew just what it meant.
Darwin saw some finchs' beaks, differently bent.
Einstein had Lenard's data, Michelson-Morley's too.
Reading these anomalies, they worked out what is true.

The cosmos has an imagination, greater than anyone.
It is difficult to outguess it, so what is to be done?
Rather: set up crucial experiments, like forks in a road.
The direction nature takes, will reveal the cosmic code.
