So I was surfing the web and came across this gem. The question is good, how does the holodeck fool Geordi’s visor?
Only on the Internet can someone ask a question about how a fictional object affects another fictional object and expect a serious answer. 
That’s why I’m asking in Cafe Society rather than GQ.
It doesn’t. I don’t have an episode name/number, but I remember Geordi saying that he can see if something is “photonic” or not on the holodeck.
Justin_Bailey: People do quite difficult degrees at university purely on fiction. I’m not putting Star Trek up there with great literature, but there’s nothing wrong with a question.
