Dark Matter May Have Electric Charge and Emit 'Dark Light'?

"Dark light(TM)" has to be an oxymoron...

Glad I wasn't the only one who thought so...

This is not controversial... it is only our "detectors" that make any light "visible", or for that matter, audible.
We like to call things like infrared and ultraviolet "invisible" forms of light, yet there are both natural and manmade receptors for these aspects of light that make them perfectly visible. Meanwhile, our rods and cones, photographic plates, thermocouples, etc. detect other aspects of light which are equally invisible to other "receptors" in nature. In addition, there is the processor, eg. our brain or a computer, that interprets the received signals and somehow conceptualizes them as "light". In radio technology, obviously, the processing of radio signals results in the vibration of a speaker producing sound. If our photoreceptors worked this way, we would hear colors instead of seeing them.

Something which actually radiated darkness would likely have to involve Lucas (the guy who used to make the electrical systems for English cars)... I can't picture anything like that occurring in nature.

I get your joke, and the oxymoron reference. But do you realize that all light is actually completely transparent?
This attribute of space is what makes it appear "dark," in comparison to eg. starlight. But in case you didn't realize it, I am in no way supporting the concept of "dark matter" as presented in current media.

Thanks for clarifying. I thought you meant George Lucas of certain sci-fi, movie, and special effects fame... *Wink*
