>>12431828I feel like this question has more to do with the ambiguity of language if anything, and less to do with science.
If you go with the Wikipedia definition of light, then the term only applies to electromagnet energy in the visible spectrum. Darkness, meanwhile, is generally understood to be the absence of light. So then, dark light is light that is absent of itself.
But then we have terms like "speed of light" which technically apply to any particle absent of mass, so photons. Well, if photons are light, then this muddies things a lot.
Again, this isn't a question pertaining to science so much as it is one that pertains to the limits of language.
