Is the nature of light observed only indirectly after its interaction with matter? We currently lack an experimental technique which would isolate the nature of light without the use of matter i.e., a detector. We will present additional experiments which, although again indirect, may reveal new understandings (but mostly more questions) about the nature of light. This talk will not report research results, but rather be an invitation for others to conduct similar such measurements as will be proposed. Past measurements have measured no absorption of radiation in the dark fringe (concluding no light is present due to canceling of the fields). Does the radiation in a dark fringe cause stimulated emission? What are the photon statistics in a dark fringe?
