To virtual numbers,
Invisible dimensions,
And fictitious proxy waves,
We must now add imaginary time.
A tiny polydimensional shape
Perpendicular to real time
With the whole history of real time
Encoded like a hologram
Upon its bumpy surface.
Since existence must be either
In both real and imaginary time
Or in neither
One must suppose
That there is no imaginary time
In the realm of light
Either.
