'Negative energy' (Was 'the aether and...)

..the nature of "negative time" could
hypothetically embody the fastest (and
shortest wavelenght) state, don't you
think so?

Nah, dunno what you mean by "negative time".
The term "negative energy" was only used as an
expedient, taking Dirac's use of the term and applying it to the domain
below the Planck baseline. In reality it is no more "negative" than the
high octaves of a piano keyboard are "negative" to the lowest octave.
It's all one unbroken continuum.

That lowest octave, in terms of energy density, represents the material
universe, its Table of Elements, and its thermodynamics. Whereas the
ascending octaves represent the sub-Planck domain and its ascending
levels of energy density.
Consider this statement: There is NO PERCEPTIBLE UPPER LIMIT TO THE
AMPLITUDE OF ENERGY TRANSMISSIBLE BY EM RADIATION.

What does this say about the energy density of the carrier medium?
