The speed of light is universal,
A physics constant we’ve all heard of.
It does not matter where you stand.
But are there ‘buts’ and are there ‘ands’?
Light is slowed when it goes thru
Air or glass or water too.
Can its speed ever be
Faster yet than what we see?
The rate of change within a frame
May exceed: that’s not the same
Tho our semantics it may vex
It’s not the speed of an object
“c” – the massless speed that’s fastest,
A description that has lasted.
Fete the knowledge it affords,
Or feel sorry for… the good Lord.
