Radio(television) waves are "LIGHT".. as fully as infra red, micro waves and sunlight.. Radio waves carry music, talk, news, and other kinds of data(FM) <- like garage door opener signals.. Light can hold much "information"..
Light transduced by the human brain decrypts all vision.. The images are there whether the eye sees them or not.. Images of what is or seems to be..
The ghost in the machine may not be a ghost at all but some form of "light".. spectors of a spirit.. Light is NOT matter(photons).. yet is real.. There is only a little jump in logic to seeing matter become spirit.. Is matter / light in essence or can light become matter?..
What spirit/Spirit is no one knows.. as fully as few or no one knows what "light" is.. Some it is a "wave".. a field of something.. Spirit may be as real as any matter.. maybe more real than matter.. Light may be the source of what matter "IS".. and matter is just light stored as water is storage for hydrogen and oxygen.. and crude oil is storage for a range of other chemicals..
