This stimulates a speculation -- perhaps there are several distinctly
different phenomena that are all perceived as light by humans, but are
actually each of unique origin.
So, one type would be "photonic" light, which is generated by photons
impacting on a medium. This type of light is also part of the
Cerenkov light, coming from some kind of neutrino emission, is another.
A few years ago, Michael Theroux did some documentation on a type of light
that sometimes precedes earthquakes, and apparently results from a
longitudinal wave form created by tension in rock layers.
Positrons might generate another kind of non-photonic light under certain
And of course i have to wonder if the light generated from as yet
hypothetical collisions of matter and antimatter would also be non-photonic.
When considering this pure speculation, keep in mind that human perceptual
systems are specifically designed to filter out most energy patterns in the
