"Electromagnetic radiations’ speed
We learned that it took
Eight minutes for light
To reach us from the Sun
And two and one-half years
From the next nearest star,
And an astronomical variety of other
Greater and different time lags
For light to reach us
From each of the other
Myriads of stars.
"These time lags were far different
From instantaneous and simultaneous.
And experiments made evident
That such light sources
Are always exhausting
Their local energy concentrations,
Wherefore they cannot be eternal.
"Prior to that measurement
The illusion of 'instantaneity
Induced false concepts
